Abstract:
The pterosaurs first appear in the fossil record in the middle of the Late Triassic. Their earliest representatives are known from Northern Hemisphere localities but, by the end of the Jurassic Period, this clade of flying reptiles achieved a global distribution, as well as high levels of diversity and disparity. Our understanding of early pterosaur evolution and the fundamental interrelationships within Pterosauria has improved dramatically in recent decades. However, there is still debate about how the various pterosaur subgroups relate to one another and about which taxa comprise these. Many recent phylogenetic analyses, while sampling well from among the known Triassic and Early Jurassic pterosaurs, have not included many non-pterosaurian ornithodirans or other avemetatarsalians. Given the close relationship between these groups of archosaurs, the omission of other ornithodirans and avemetatarsalians has the potential to adversely affect the results of phylogenetic analyses, in terms of character optimisation and ingroup relationships recovered. This study has addressed this issue and tests the relationships between the early diverging pterosaur taxa following the addition of avemetatarsalian taxa and anatomical characters to an existing early pterosaur dataset. This study has, for the first time, included taxa that represent the aphanosaurs, lagerpetids, silesaurids and dinosaurs, in addition to early pterosaurs. Anatomical characters used in other recent studies of archosaurs and early dinosaurs have also been incorporated. By expanding the outgroup taxa and anatomical character coverage in this pterosaur dataset, better resolution between the taxa within certain early pterosaur subclades has been achieved and stronger support for some existing clades has been found; other purported clades of early pterosaurs have not been found in this analysis—for example there is no support for a monophyletic Eopterosauria or Eudimorphodontidae. Further support has been found for a sister-taxon relationship between Peteinosaurus zambelli and Macronychoptera, a clade here named Zambellisauria (clade nov.), as well as for a monophyletic and early diverging Preondactylia. Some analyses also support the existence of a clade that falls as sister-taxon to the zambellisaurs, here named Caviramidae (clade nov.). Furthermore, some support has been found for a monophyletic Austriadraconidae at the base of Pterosauria. Somewhat surprisingly, Lagerpetidae is recovered outside of Ornithodira sensu stricto, meaning that, based upon current definitions at least, pterosaurs fall within Dinosauromorpha in this analysis. However, fundamental ornithodiran interrelationships were not the focus of this study and this particular result should be treated with caution for now. However, these results do further highlight the need for broader taxon and character sampling in phylogenetic analyses, and the effects of outgroup choice on determining ingroup relationships.

Abstract:
Pterosaurs were widespread during the Late Cretaceous, but their fossils are comparatively rare in terrestrial depositional environments. A large pterosaur bone from the Kaiparowits Formation (late Campanian, ~76–74 Ma) of southern Utah, USA, is tentatively identified as an ulna, although its phylogenetic placement cannot be precisely constrained beyond Pterosauria. The element measures over 36 cm in preserved maximum length, indicating a comparatively large individual with an estimated wingspan between 4.3 and 5.9 m, the largest pterosaur yet reported from the Kaiparowits Formation. This size estimate places the individual at approximately the same wingspan as the holotype for Cryodrakon boreas from the penecontemporaneous Dinosaur Park Formation of Alberta. Thus, relatively large pterosaurs occurred in terrestrial ecosystems in both the northern and southern parts of Laramidia (western North America) during the late Campanian.

A new non-monofenestratan pterosaur with multicusped dentition,Seazzadactylus venieri, is described from the Upper Triassic (middle-upper Norian) of the Carnian Prealps (northeastern Italy). The holotype ofS. venieripreserves a complete mandibular and maxillary dentition, along with a nearly complete premaxillary one, showing unique features. Furthermore, the arrangement of the premaxillary teeth and the shape of jugal, pterygoid, ectopterygoid, scapula and pteroid are unique within non-monofenestratan pterosaurs.S. venieriis similar and closely related toCarniadactylus rosenfeldiandAustriadraco dallavecchiai, which are also from the Alpine middle-upper Norian of Italy and Austria, respectively. In a parsimony-based phylogenetic analysis,S. venieriis found to nest within a clade of Triassic pterosaurs composed ofArcticodactylus cromptonellus,Austriadraco dallavecchiai, Carniadactylus rosenfeldiand a trichotomy ofRaeticodactylus filisurensis,Caviramus schesaplanensisand MCSNB 8950. This unnamed clade is basal within the Pterosauria, but is not the basalmost clade.Eudimorphodon ranziilies outside this clade and is more derived, making the Eudimorphodontidae paraphyletic.S. venieriincreases the diversity of Triassic pterosaurs and brings the number of pterosaur genera and species in the Dolomia di Forni Formation to four.

Abstract:
ABSTRACTThe state of Texas has one of the greatest records of pterosaurs in the world, surpassing all other US states and most countries in the number of occurrences. Uniquely, this record extends over the entire 150+ million history of the Pterosauria. A review of this pterosaur record confirms at least 30 pterosaurs known from 13 occurrences, including five valid species. The holotypes of two of these species have been described before and are diagnosed and erected here as the new speciesRadiodactylus langstoni, gen. et sp. nov., named in honour of Dr. Wann Langston Jr, the father of Texas pterosaurology, andAlamodactylus byrdi, gen. et sp. nov.. Phylogenetic analysis of all Texas pterosaurs that can be coded for more than one character confirms that these species are distinct from others and occupy phylogenetic positions close to their original classifications.Radiodactylus langstoniis recovered as a non-azhdarchid azhdarchoid,Quetzalcoatlus northropias an azhdarchid,Alamodactylus byrdias a non-pteranodontoid pteranodontian,Aetodactylusas a pteranodontoid, andColoborhynchus wadleighias an ornithocheirid. The presence of eudimorphodontid, dsungaripterid, as well as other azhdarchid and pteranodontoid pterosaurs, is also confirmed in Texas.

Abstract:
Leaping from branch to branch - Lagerpetidae and the origin of pterosaurs. Pterosaurs are a group of extinct flying reptiles with emergence in the Triassic and great radiation in the Jurassic and Cretaceous, being the first vertebrates to develop active flight. Since the first pterosaurs already show morphologic patterns that are typical for the clade, there is a substantial gap between the first preserved pterosaurs in the fossil record and their closest relatives. Here, we discuss different phylogenetics proposals presented through decades, being the Dinosauromorpha–Pterosauromorpha Hypothesis the most usually recovered. Even considering this hypothesis, however, the morphological gap persists. Thus, we discuss how the knowledge about Lagerpetidae has helped to elucidate the origin of pterosaurs, since recent works indicates that the group would be nested inside the Pterosauromorpha. Lagerpetidae is a group of small reptiles found in the Upper Triassic of North America, Brazil, Argentina and Madagascar, with the Carnian record thus far restricted to the South hemisphere, and with the first records for North America being Norian in age. Recent discoveries point to the presence of insectivorous dentition among Lagerpetidae, as it happens in Triassic pterosaurs. Thus, insectivory can be assigned as an ancestral diet in Pterosauromorpha. This diet is assigned as a possible driving force to the evolution of flight in Pterosauria. Keywords: Pterosauria, Lagerpetidae, Ornithodira, Triassic.

Abstract:
The mass, wingspan, and wing area of pterosaurs were reconstructed. Mass was estimated by determining volume and multiplying by avian density. This method was considered appropriate only for smaller pterosaur species because there is evidence for lower density in larger species. These reconstructions were used to compare the wing shapes of Triassic and Jurassic pterosaurs with those of birds. Pterosaurs had wings of below-average loading and above-average aspect compared to the avian mean. This wing design was compatible with relatively slow and highly efficient flight, with high maneuverability. Wing area depends on the reconstruction model adopted; wings attached to the hindlimb principally reduced aspect, and secondarily reduced loading, which would improve take-off performance at the expense of efficiency. The wing shape and cranial feeding adaptations of pterosaurs were most compatible with a marine or aerial predatory adaptive zone. The reconstructed pterosaurs show a limited range of wing shape compared to birds. This may partly reflect preservational bias favoring species living in marine or lagoonal environments, but this is not a complete explanation because there is a lack of pterosaurs with wings of high loading like the marine ducks and auks. Structural, physiological, or adaptive factors may have limited pterosaur wing shape.

Abstract:
An isolated pterosaurian caudal cervical (~ postcervical) vertebra was recovered from the Upper Cretaceous Lapurr sandstone ofWest Turkana, northwestern Kenya. The vertebral centrum is short, wide, and dorsoventrally compressed. Although the specimen is lightly built similar to most pterosaurs, it is here referred to Pterodactyloidea and tentatively to the Azhdarchidae in that it lacks pneumatic features on both the centrum and neural arch. This represents one of the few pterosaurs recovered from the entirety of Afro-Arabia, the first pterosaur recovered from the Cretaceous of East Africa, and, significantly, a specimen that was recovered from fluvial deposits rather than the near-shore marine setting typical of most pterosaur discoveries.

Abstract:
The fossil record of Australian pterosaurs is sparse, consisting of only a small number of isolated and fragmentary remains from the Cretaceous of Queensland, Western Australia and Victoria. Here, we describe two isolated pterosaur teeth from the Lower Cretaceous (middle Albian) Griman Creek Formation at Lightning Ridge (New South Wales) and identify them as indeterminate members of the pterodactyloid clade Anhangueria. This represents the first formal description of pterosaur material from New South Wales. The presence of one or more anhanguerian pterosaurs at Lightning Ridge correlates with the presence of ‘ornithocheirid’ andAnhanguera-like pterosaurs from the contemporaneous Toolebuc Formation of central Queensland and the global distribution attained by ornithocheiroids during the Early Cretaceous. The morphology of the teeth and their presence in the estuarine- and lacustrine-influenced Griman Creek Formation is likely indicative of similar life habits of the tooth bearer to other members of Anhangueria.

Abstract:
Pterodactylus from the uppermost Jurassic of southern Germany represents one of the most iconic pterosaurs, due to its status of being the first member of the Pterosauria to have been described and named. During the early phase of pterosaur research, Pterodactylus was a wastebasket taxon containing dozens of sometimes distantly related assigned species. Decades later, a comprehensive revision of the genus significantly reduced the number of species. To date, only one species remains in the genus, Pterodactylus antiquus, although the referral of several specimens to this taxon and the taxonomic relationships of them is still debated. Thus far, the genus has been only reported from the Upper Jurassic Plattenkalk deposits of Bavaria, and all of these occurrences are Tithonian in age. Here we describe the first record of Pterodactylus from the Torleite Formation near Painten (Bavaria), which represents the first occurrence of the genus from the Kimmeridgian. The specimen is a complete, articulated and exquisitely preserved skeleton of a small-sized individual. Aside from its old geological age, it is a typical representative of the genus, greatly resembling other specimens from younger strata. Certain characters, such as the overall size, skull length, relative orbit size, and phalangeal formula indicate that the specimen from Painten represents a juvenile to young subadult individual, an ontogenetic stage rarely found among Pterodactylus specimens. The find significantly expands the temporal range of the taxon and represents one of the best-preserved specimens of the genus reported so far.

Pterossauros são um dos grupos de arcossauros fósseis melhor representados no registro fóssil brasileiro. Dentro desta diversidade, uma das primeiras espécies descritas, Cearadactylus atrox, tem causado divergências de interpretação entre pesquisadores desde a sua publicação. Devido ao fato de o holótipo e único espécime conhecido estar parcialmente preparado, as tentativas de classificações taxonômicas realizadas, posicionaram-no em grupos diferentes. Estas discordâncias geraram o colapso de certos ramos da filogenia de Pterosauria. O presente trabalho teve como objetivo a preparação do holótipo de Cearadactylus atrox, sua re-descrição e o posicionamento filogenético, utilizando-se matrizes filogenéticas disponíveis para o grupo. Evidências de adulterações foram observadas durante a preparação. Dentre as características exclusivas apresentadas por Cearadactylus atrox estão uma fenda no dentário bifurcada na extremidade rostral, órbita e narina em posição elevada relativo a fenestra nasoanterorbital e menos de 15 dentes em cada lado da maxila e mandíbula. Filogeneticamente Cearadactylus atrox se mostrou como grupo irmão do clado Anhangueridae, sendo uma espécie intermediária entre as formas européias (nominalmente Ornithocheirus compressirostris) e as formas brasileiras (Tropeognathus mesembrinus e as espécies que compõem o gênero Anhanguera)

Os pterossauros são um grupo extinto de répteis alados que surgiu há pelo menos 228 milhões de anos, sendo encontrados no Brasil em rochas triássicas do Paraná e cretáceas do Nordeste. Dentro deste registro, o clado Anhangueridae, é documentado nas concreções calcárias da Formação Romualdo, Aptiano/Albiano da Bacia do Araripe. A esse grupo atribuímos um novo espécime LPU 017, um crânio completo preservado tridimensionalmente, com alguns ossos deslocados e a presença de dentes. Após sua preparação destacou-se uma grande e alta crista sagital pré-maxilar, característica distintiva deste grupo de pterossauros, além das características exclusivas deste exemplar. Dentre elas estão a presença de 35 pares de alvéolos; uma quilha palatal relativamente robusta; uma elevada expansão em forma de colher na pré-maxila; a presença do 5º, 6º e 7º pares de dentes menores do que o 4º e 8º; forma convexa do palato na porção rostral e o tamanho e localização da crista sagital pré-maxilar. Tais características exclusivas permitiram identificar LPU 017 como um novo gênero e espécie de pterossauro atribuído ao clado Anhangueridae. Esse resultado foi corroborado pela análise filogenética, obtida com uma matriz de 54 táxons e 89 caracteres, que gerou 9 árvores igualmente parcimoniosas. Para verificar os padrões de diferenciação craniana no clado Anhangueridae, utilizamos a morfometria geométrica, que compara a forma dos organismos, levando em consideração o caráter geométrico das formas biológicas e analisa estatisticamente sua variação. Verificamos então que crânios e cristas nesse clado crescem de forma isométrica, o oposto da realidade dos membros posteriores, onde o crescimento ósseo é alométrico. Nesse clado em especial a ontogenia não interferiu nos resultados, pois crista e crânio seguiram o mesmo padrão de crescimento, inclusive em indivíduos de estágios ontogenéticos diferentes, como ocorreu no agrupamento de Anhanguera araripensis e Anhanguera blittersdorffi

O clado Pterosauria é constituído por répteis alados que viveram durante a Era Mesozóica (entre 215 a 65 milhões de anos antes do presente) e habitaram diversas regiões do planeta. Pertencente a este clado, o g rupo Tapejaridae é caracterizado principalmente pela peculiar morfologia rostral e por não possuir dentes. O estudo filogenético de tapejarídeos do nordeste do Brasil é baseado na sua maioria em elementos do crânio, devido à escassez de esqueletos pós-cranianos. Este estudo descreve morfologicamente e classifica, através de análise filogenética, um novo espécime atribuído à Tapejaridae, proveniente da Formação Romualdo (Grupo Santana, Bacia do Araripe, CE). O material compreende dez vértebras articuladas (as três últimas cervicais e também as sete primeiras dorsais que se fusionam, formando o notário), o escapulocoracóide direito, a escápula e o coracóide esquerdos, um fragmento de esterno, o úmero direito parcialmente preservado, um fragmento da 4a falange do dígito alar, a porção distal do femur direito e a porção proximal da tíbia/fíbula . Foram geradas três árvores na análise filogenética, sendo que em duas delas AMNH 22567 foi posicionado dentro de Thalassodrominae . Contudo, na outra árvore o espécime se pocisionou como Tapejaridae basal. Mesmo assim, sua assignação como Thalassodrominae se justifica pela presença de três foramens posicionados dorsal e lateralmente ao canal neural nas vértebras cervicais; presença de notário e presença de um forâmen pneumático ventral na porção proximal do úmero. Estes materiais são os mais completos elementos pós-cranianos deste grupo de pterossauros descritos até o momento. Com relação à paleobiogeografia, Tapejaridae aparenta ter surgido no oeste da Eurásia durante o Neojurássico, migrando para sudoeste e dando origem as formas eocretácicas da Bacia do Araripe.
Pterosauria is a clade composed of flying reptiles that lived during the Mesozoic Era (215 to 65 million of years before present) and inhabited various regions of the world. Within this large clade, Tapejaridae is mainly characterized by peculiar rostral morphology and absence of tooths. The phylogenetical studies of the tapejarids from northeastern Brazil are mainly based on cranial elements, due to shortage of postcranial skeletons. This study described and classified through a phylogenetical analysis, a new specimen ascribed to Tapejaridae from Romualdo Formation (Araripe Basin, CE), housed at the American Museum of Natural History (under the acronym AMNH 22567) and comments on the paleobiogeography of this group. The material comprises ten articulated vertebrae (three cervicals and seven subsequent dorsals fusioned, ones forming the notarium), a right scapulocoracoid, a left scapula and a left coracoid, a partial sternum, a right humerus, a fragment of 4th phalanx of the alar digit, a distal fragment of right femur and a fragment of the proximal portion of the right tibia/fibula. The phylogenetical analysis generated three different topologies, two of them placing AMNH 22567 within Thalassodrominae (subclade of Tapejaridae). In the other one, the specimen was placed in a basal position within Tapejaridae. Nonetheless, the presence of three foramina lateral and dorsal to the neural canal of the cervical vertebrae, the presence of a notarium and presence of a pneumatic foramen on the ventral side of the proximal portion of the humerus allow its assignation as a Thalassodrominae indet. The specimen comprises the more complete postcranial material for this subfamily described so far. Regarding the paleobiogeography of Tapejaridae, it appears to originated in western Eurásia during the Neojurassic and later migrated to southwest and irradiated to new Eocretacic forms in Araripe Basin.

No ano de 2009, em uma mineradora de calcário laminado próxima à cidade de Nova Olinda (Ceará, nordeste do Brasil), um crânio parcial de pterossauro foi encontrado. O novo material, objeto de estudo do presente trabalho, é proveniente de estratos eocretácicos da Formação Crato (Bacia do Araripe). Trata-se do quarto espécime conhecido de Tupandactylus imperator (Pterosauria, Tapejaridae) e o primeiro com mandíbula associada. O estudo deste espécime contribuiu significativamente com informações a respeito da anatomia e relações filogenéticas de T. imperator e outros pterossauros tapejarídeos, resultando na publicação de um artigo científico. No presente trabalho, além da descrição anatômica detalhada e estudo filogenético do novo exemplar, revisamos a ocorrência de pterossauros no Grupo Santana da Bacia do Araripe, com ênfase em T. imperator. Questões taxonômicas, como as relações filogenéticas de pterossauros tapejarídeos e a validade de Tupandactylus navigans são, também, discutidas.
In the year of 2009 a partial pterosaur skull was found in a limestone quarry near the city of Nova Olinda (Ceará State, northeastern Brazil). The new material, object of study of the present work, comes from the Early Cretaceous strata of Crato Formation, Araripe Basin, being the fourth known specimen of Tupandactylus imperator (Pterosauria, Tapejaridae) and the first one with associated lower jaw. The study of this specimen added new significant information on T. imperator anatomy and phylogenetic relationships, and resulted in the publishing of a scientific paper. At the present work we describe the new specimen in detail, study its phylogenetic relationships and review pterosaur occurrence in the Santana Group of Araripe Basin (with emphasis on T. imperator). Taxonomic issues as Tapejaridae relationships and the validity of Tupandactylus navigans are also discussed.

Abstract:
For 130 years dinosaurs have been divided into two distinct clades – Ornithischia and Saurischia. This dissertation looks at the earliest evolution of the clade Dinosauria by focusing upon the interrelationships of the major subsidiary clades within it. It does this following examination, comparison and description of early dinosaur material, and by utilising modern phylogenetic analysis techniques, to rigorously and objectively test the fundamental groupings within the clade Dinosauria using a newly compiled dataset of early dinosaurs and other dinosauromorphs (= close dinosaur relatives). The current consensus on how the principal clades within Dinosauria (Theropoda, Sauropodomorpha and Ornithischia) are related to one another is challenged by the results of these analyses. This study finds, for the first time, a sister-group relationship between Ornithischia and Theropoda, here termed Ornithoscelida. Consequently, a new definition for Dinosauria is presented, as the historic definition would exclude all members of Sauropodomorpha from the clade. As well as this, I propose revisions to the definitions of each of the principal dinosaurian sub-divisions and propose a new timeframe and geographic setting for the origin of Dinosauria. These new hypotheses force re-evaluations of early dinosaur cladogenesis and character evolution, suggest the independent acquisition of hypercarnivory in multiple dinosaur groups and offers an explanation for many of the anatomical features previously regarded as striking convergences between theropods and early ornithischians. As well as presenting new anatomical data on many early dinosaurs and dinosauromorphs, including a comprehensive re-description of the postcranial anatomy of Lesothosaurus diagnosticus (Chapter 2), and a new anatomical dataset of early dinosaurs (the largest ever compiled), this thesis goes on to implement the new dataset to investigate a number of important outstanding questions about early dinosaur evolution and provides new lines of enquiry for future workers to pursue. The results of this thesis reveal the oldest known members of the dinosaurian clades Theropoda and Sauropodomorpha (Chapter 6), as well as a new clade within Ornithischia; a taxon previously thought to represent a derived theropod has been recovered as a potential ‘missing link’ between theropods and ornithischians using the new dataset. This work now provides a unique tool for the assessment of the phylogenetic affinities of early dinosaurs and dinosauromorphs and, once published, will hopefully become the benchmark dataset for palaeontologists working in this area.

Abstract:
The Pterosauria is an enigmatic group of volant reptiles from the Mesozoic. Despite demonstrating conspicuous apomorphic conditions, including an enlarged humeral deltopectoral crest, elongate wing spar comprising the fourth manual digit, and unique skull bone configurations, their cladogenesis is uncertain. While the ingroup monophyly of Pterosauria is clear, their interrelationships are contentious. The earliest studies of pterosaur phylogeny were concerned with phenotypic groups. The earliest cladistic analyses of pterosaurs in the late 20th Century were simple and were superseded by more comprehensive analyses in the early 21st Century. These analyses are comparable at the genus, family, and suborder level, but the ranks between these are incongruent between authors, leading to nomenclatural disputes. This study aims to understand the differences that exist between the competing phylogenetic hypotheses, why they exist, and to establish a more robust phylogenetic hypothesis. An extensive review of pterosaur phylogeny, cladistic character coding, and data transformation is performed. A distinct cladistic analysis is developed independently of the literature, providing a reference tree for a meta-analysis of topological congruence. Furthermore, this distinct analysis is supplemented with published characters to produce a comprehensive analysis which is a robust hypothesis of pterosaur phylogeny. Taxonomic actions are taken on the wastebasket taxon Pterodactylus and the paraphyletic genus Germanodactylus, to improve the taxonomic content of the analyses. The results demonstrate that analyses sharing characters produce trees with greater levels of congruence. Although this may be due to the introduction of biases, it is far more likely that the improvement seen in the comprehensive tree at least, is due to improving the phyletic content, sampling of anatomy, and reducing the negative effects of homoplasy. This is supported by the comprehensive tree's congruence to the stratigraphic record. The comprehensive tree agrees with the common clades of other studies, but some families are found in unique positions, most notably the Anurognathidae.

Abstract:
The taxonomy and locomotory methods of pterosaurs have been extensively scrutinised for as long as pterosaurs themselves have been known, but comparatively little research has been conducted into their lifestyles and habits. Pterosaurs have largely been interpreted as Mesozoic equivalents of modem marine birds, principally foraging through flight-based methods of dip- or skim-feeding. Here, several lines of enquiry suggest that pterosaurs were considerably more ;ologically diverse that previously anticipated.

Abstract:
The taxonomic diversity of Jurassic pterosaurs is more poorly understood than that of their Cretaceous counterparts. Early to Middle Jurassic pterosaur-bearing formations are rare and suffer from a low fossil yield, resulting in an apparent Late Jurassic diversity spike. Recent studies have suggested this is a preservational bias rather than a taxonomic signal, however this is difficult to test given the low number of sizeable Jurassic pterosaur collections. The United Kingdom possesses Lower, Middle and Upper Jurassic pterosaur bearing horizons containing hundreds of fossils, making it one of the best Jurassic assemblages suitable for testing taxic diversity. Lower Jurassic deposits remain low yield but include the holotypes of Dimorphodon and Parapsicephalus. Parapsicephalus has previously been synonymised with Dorygnathus but is found to be a unique genus. An isolated humerus is identified as a campylognathoidid, marking the first occurrence of the group in Britain. The Middle Jurassic Taynton Limestone Formation (informally known as the Stonesfield Slate) has yielded more than 400 isolated pterosaur fossils with only one named genus, Rhamphocephalus. The type of Rhamphocephalus, is identified here as a teleosaurid skull table with the genus considered a nomen dubium. A new genus is erected for an isolated mandible and the Taynton Limestone Formation is found to include at least 3 pterosaur taxa. The Middle-Upper Jurassic Oxford Clay Formation is found to have a low diversity with the only named genus, Rhamphorhynchus jessoni, identified as a nomen dubium. The Upper Jurassic Kimmeridge Clay Formation has produced at least 4 pterosaurs, including a new species of Rhamphorhynchus. These findings suggest that Jurassic pterosaur diversity has been underestimated and is most likely higher than traditionally believed.
