Full textThe locality of Jbel Tselfat corresponds to a series of outcrops located in northern Morocco, close to the city of Meknes. The fossiliferous layers are formed by black shales dated as Upper Cretaceous and included in a thrust sheet. In spite of the poor fossil preservation, it constitutes one of the most diversified actinopterygian fauna of this epoch, with 21 taxa represented by about 400 specimens. Two fieldworks organized in 2008 and 2009 permitted to collect rock samples and about 100 fossil specimens, including some plant remains and an ammonite. The taxonomic review of 12 actinopterygian taxa has been performed and permitted to discuss their phylogenetic relationships. The inclusion of Paravinciguerria among stomiatiforms, as previously proposed and debated, is confirmed. Clupavus maroccanus is considered as a basal Otophysi, showing a modification of the anteriormost vertebrae, which can be considered as a Weberian apparatus. The genera Idrissia and Kermichthys, rare in the locality, cannot be re-attached to any major teleost clade; the genus Protostomias is considered as a euteleost incertae sedis. A phylogenetic analysis including these five taxa and some extant teleost clades has been performed, but the results are not significant. The position of these taxa is supported by homoplastic characters or by characters corresponding to missing data optimized during the analysis. The revision of the species Elopopsis microdon and the genus Tingitanichthys confirms their position within the Pachyrhizodontoidei. The aspidorhynchiform retrieved in the locality is closely related to Belonostomus crassirostris, but a more complete description of the holotype (coming from the Cenomanian levels of Pietraroia, in Italy) is needed to confirm this identification. The specimens previously attributed to “Diplomystus” brevissimus are considered as Armigatus sp. Finally, the relationships of the elopiform Davichthys lacostei, the aulopiform Ichthyotringa africana and the tselfatiiform Tselfatia formosa did not change in comparison with the previous works. An analysis of the black shales samples permit to reconstruct the deposit environment as marine, deep and quiet. They are correlated to the Oceanic Anoxic Event 2, an event of massive burying of sediments rich in organic matter, dated from the Cenomanian-Turonian boundary. Without any identifiable microfossils, this age is tested and confirmed by a comparative approach founded on the sharing of actinopterygian species, with a sample of Cenomanian and Turonian localities

Full textAs windows into the deep history of neuroanatomy, endocasts may provide information about the central nervous system of fossil taxa. Based on exceptionally preserved specimens of coeval mosasauroids (Squamata) and plesiosaurians (Sauropterygia), from the Turonian outcrops of Goulmima (Southern Morocco), the aim of this work was to describe for the first time in detail the endocranial anatomy of these two major clades of Mesozoic marine reptiles to provide insights about their sensory abilities, and thus to understand their cohabitation, interactions and niche partitioning. The endocranial anatomy of related extant squamates, mainly snakes but also varanids and amphisbaenians, also almost unknown until now, has been performed for the first time and used for comparative purpose to analyze the form-function relationships associated to endocasts. The analysis of the endocranial variability in extant squamates pointed out that endocasts reflect both phylogenetic and ecological signals, and that the relative size of each endocranial structure can be used to reveal differences in vision and olfaction according to taxa. Among fossil taxa, computed tomography was used to reconstruct in detail the cranial morphology of three unpublished specimens of Plesiosauria. These specimens have been examined and described, two have been referred to the elasmosaurid Libonectes morgani and the third one is an indeterminate polycotylid. The 3D morphology of the endocast has been reconstructed for these plesiosaurian specimens and the basal mosasauroid Tethysaurus nopcsai. The results show that the endocranial morphology of Plesiosauria differs from that know in other extinct and extant vertebrates. Based on the relative size of the structures composing their endocasts, both the mosasauroid Tethysaurus and the plesiosaurians seem to rely more on vision than on olfaction to interact with their environment. However, these new endocast data, added to information already available in the literature suggest different modes of locomotion and hunting techniques, which probably allowed them to coexist in Goulmima as quaternary consumers
