Abstract:
Alexander James Edward Cave (1900–2001) was a superb anatomist who extensively improved our knowledge of rhinoceros anatomy and osteology; he also published several studies on the osteology of other groups of mammals and one conservation-focused study about numbers of Ceratotherium cottoni in Uganda. Our contribution contains an identification of the rhinoceros specimens examined by A. J. E. Cave, his complete bibliography related to rhinoceroses, and two recommendations in accord to his legacy. All Cave’s morphological and genetic studies should specify the exact geographic origin of the wild rhinoceroses, if known, and some unambiguous reference numbers in the case of collections and/or captive-based specimens. Cataloguing of extinct and near-extinct extant rhinoceroses in world collections, future preservation of the collection material and its anatomical/morphological documentation for the last remnants of Ceratotherium cottoni, Dicerorhinus sumatrensis, as well as Rhinoceros sondaicus and localized wild-based specimens of Diceros bicornis is highly recommended.

Abstract:
Collection of proper autopsy specimen and preservation are essential stepsfor the toxicological analysis in Forensic Medicine. Faulty collection and preservation of the specimens/samples can greatly alter or negate forensic chemical or toxicologicalexamination. In forensic toxicology practicein Bangladesh, postmortem specimen that is subjected to toxicological examinations generally focusing on mainly blood and sometimes urine or other fuds from different body cavities. Analysis of blood from different anatomical sites and tissue samples and urine may assist in the interpretation of the postmortem results. However, in many postmortem cases, there is little or no blood for quantitative drug analysis, or there might be such traumatic injury which led to significant blood loss or there is possibility of contamination form contents of the ruptured stomach. Besides, analysis of urine reveals negative result, if death occurs closely the time of intoxication. Given the circumstances, brain tissue may be a valuable specimen in postmortem toxicological analysis. The position of the brain in the body secures a tremendous protection and isolation which can eliminates or at least attenuates many of the interpretive challenges with postmortem blood, urine or other fluid specimens.This review paper is an update on the standard methods of brain tissue specimen collection and preservationprocedures for toxicological analysis and its value as well as advantages over other specimens, which might be of possible interest for forensic professionals in the country.

Abstract:
Abstract Introduction: Neuroanatomy specimens have greater fragility than other anatomy specimens and their useful life depends on good conditioning and protection. The difficulty in obtaining human specimens has increased the demand for preparations that might make such specimens more durable. Objective: transform the collection of neuroanatomy specimens in the anatomy laboratory into specimens that were more instructive for students, through more refined anatomical techniques, thereby improving the appearance and preservation of these specimens, and also to develop a scientific study on the importance of this type of didactic-pedagogical tool. Material and Methods: After preparing the specimens and using them in the classroom, we applied a questionnaire to evaluate the learning process, with regard to ease of handling the specimens, improvement of instruction and construction of knowledge. We gathered responses from 53 students in their fourth teaching semester of the biomedicine course at the Methodist University of São Paulo. Results: after the treatment to clarify and demarcate anatomical structures in the neuroanatomical specimens that was put forward in this study, an effective improvement in the students' study method was demonstrated (100%). Conclusions: The objectives proposed by the discipline were achieved in terms of yield (92.5%) and understanding of theory during practical classes (98%), thus generating student behavior that was more positive. In relation to handling and discomfort relating to the smell of the old specimens, there was an improvement of 88.7% through using the current specimens. There was also an improvement in learning outside of the classroom hours (86.4%).

Abstract:
The uppermost Jurassic to lowermost Cretaceous stem turtle Pleurosternon bullockii is the pleurosternid (Testudinata, Paracryptodira) known by the largest number of specimens worldwide, composing the largest European collection of Lower Cretaceous complete and partial shells for a turtle taxon. The availability of numerous specimens as well as their generally good preservation allowed for recent detailed characterization of the shell of this species, including states that are variable at the intraspecific level (individual variability, sexual dimorphism, and ontogenetic development). However, extreme cases of morphological variation corresponding to anomalies have not been addressed in detail, neither for P. bullockii nor for any other member of Paracryptodira. In this context, the study of several shell anomalies in P. bullockii is carried out here. Fourteen specimens showing anomalies are recognized and examined here to determine the frequency and distribution of these shell anatomical deviations. All these anomalies are described and figured. The morphogenetic cause of each of them is discussed. As a consequence, a relatively broad spectrum of anomalies is reported for P. bullockii. None of the anomalies seem to present negative consequences for vital activities of the specimens since none compromised the main functions of the shell.

Abstract:
Redescription of the type and only specimen of Aigialosaurus dalmaticus (BSP 1902II501), an "aigialosaurian" squamate from the Cenomanian–Turonian of Hvar, Croatia, and, at the time of collection, the Italian island of Lesina, indicates that previous reviews of the specimen include erroneous anatomical interpretations. The type specimen presents a new and unique pelvic anatomy: the ilium of A. dalmaticus is an elongate element with well-developed anterior and posterior iliac processes. A scenario is presented for mosasaurid pelvic evolution, whereby the anteriorly elongate and dorsally directed ilium of mosasauroids is not derived from the forward rotation of the posterior iliac process, but rather the reduction of that process and the elaboration of the anterior iliac process. Recent phylogenetic analysis of Mosasauroidea finds A. dalmaticus to be the sistergroup to Opetiosaurus bucchichi and all other mosasaurids and "aigialosaurs." We examine the character state assignments for A. dalmaticus in that study and refute those assignments owing to the absence of preservation of all four characters states found to separate A. dalmaticus from O. bucchichi.

Abstract:
A constant situation present in the anatomy laboratories is represented by the cadavers preservation resulted from dissection. The main requirement for this process is the use of formaldehyde which is a toxic substance probably included in the class of carcinogenic substances. Large specimens resulted from dissection process, such as limbs or trunks, can be preserved only in large containers filled with formaldehyde and for limited periods of time. To remove these issues we used the anatomy laboratory in order to be able to preserve the first sustainable plastinated anatomical specimens. In our study have been used 8 adult human bodies (partial and complete), 6 females and 2 males, aged between 62 and 73. We have removed and dissected brains, upper limbs, kidneys and livers. They have undergone preservation process of plastination.

Abstract:
DNA extraction frequently requires destruction of whole samples. However, when the sample is very rare or has taxonomic importance, nondestructive DNA extraction is required for preservation of voucher specimens. In the case of arthropod specimens, minor anatomical structures such as a single leg or a single wing are often sacrificed instead of the whole body for DNA extraction. In an attempt to save the entire anatomical structure of specimens, several authors tried to brew the whole specimen in a lysis buffer and to extract DNA from the “soup.” We applied this nondestructive DNA extraction technique to a forensically important blowfly species, Phaenicia sericata. With nondestructive DNA extraction, a satisfactory quantity and quality of DNA for PCR amplification was obtained with only minimal anatomical disruptions that do not alter the morphologic identification. This nondestructive method may be applicable to DNA extraction of rare samples as well as vouchering of regular fly samples.

Abstract:
As one of our main topics of interest within the Department of Anatomy, the usage of biomaterials involved two directions: preparation of anatomical casts by injection and corrosion and preservation of anatomical samples through plastination. For injection we used several substances, such as polyvinyl chloride, with the solvent cyclohexanone, a polyester oil used in furnishing and glass fiber industry and mostly TECHNOVIT 7143, of German production. Another preservation method that includes the usage of biopolymers is plastination, a perfect method for the preservation of perishable biological specimens, especially for soft, putrifiable ones with high water content. The method we applied is the silicone plastination (S10) that addresses to macroscopical samples, such as internal organs (hearts, kidneys) or slices of nervous tissue (brain slices) greater than 10 mm, samples resulted from the dissection process in the Anatomy Department.

Abstract:
A known method for the preservation of green foliage was adapted in order to preserve floral tissues, retaining the colour and texture, thereby providing a method suitable for the preservation of whole flowers. Initially, the effects of the existing foliage preservation process on floral tissues were studied and the resulting problems of limp sticky petals and colour loss were identified. Subsequently, with a knowledge of basic plant anatomy and of the properties of the main floral pigments, the anthocyanins, a series of experiments on petals and whole flowers were carried out in an attempt to rectify these problems and to incorporate the remedies into a method for preserving whole flowers. The problem of improving the texture and firmness of flower heads was tackled by investigating the effects of adding bulking or setting ingredients to the process fluid and establishing their optimum concentrations. In the case of flower colour, the addition of acid was required in order to maintain the bright anthocyanin colours and a range of acids was investigated. Furthermore, since it is known that in nature the anthocyanin pigments are stabilised by metal ions and copigments, the use of these agents in the preservation process was also considered. This empirical work was then validated by confirming the identity of the main pigments involved and by studying various aspects of the new preservation process. Factors examined included acid concentration, temperature, solvent composition and the addition of metal ions and copigments to solutions of petal extracts containing anthocyanin pigments. Physical changes resulting from processing, including process fluid content and the moisture absorption properties of processed petals were also measured. Finally, the application of a selection of coating materials was assessed in an attempt to increase the life span of the processed flowers by providing extra protection against environmental stresses.

Abstract:
The key character separating the dendrochirotid families Sclerodactylidae (sensu Pawson & Fell, 1965) and the Phyllophoridae (sensu Pawson & Fell, 1965), i.e. entire or undivided radial processes to the calcareous ring in the former and sub-divided processes in the latter, is unjustified since most sclerodactylid species also have subdivided processes. It is here assumed that the basis of elevating the subfamily Sclerodactylinae Panning to family level was established on a misinterpretation or mistranslation of the original diagnosis of this subfamily or a lapsus calumni meaning “plates” instead of “processes”. Panning (1949) categorically states that the processes in the Sclerodactylinae are composed of 3–4 large pieces of calcite and only as an exception they are unbroken. Since Pawson & Fell gave no other distinction between the Sclerodactylidae and the Phyllophoridae, the former is here considered an invalid taxon and its three current subfamilies (Sclerodactylinae, Sclerothyoninae Thandar and Cladolabinae Heding & Panning) are re-assigned to the Phyllophoridae. This family now includes six subfamilies: Cladolabinae, Phyllophorinae Östergren, Sclerodactylinae, Sclerothyoninae, Semperiellinae Heding & Panning and Thyoninae Panning. The diagnosis of the Sclerodactylinae, restricted by Thandar (1989), is now modified to include also those forms whose radial and interradial plates may be slightly sub-divided but still form a short tube. Of the eleven genera placed within this subfamily subsequent to its erection, only ten of these remain. Neothyone Deichmann is a preoccupied name for which Lisacucumis is here proposed as a replacement. Thandar’s (1989) diagnosis of the Thyoninae is here accepted, however, the genus Thorsonia Heding is transferred to the Sclerodactylinae. Of the 66 nominal species which currently stand in the “supergenus” Thyone Jaeger, 10 are transferred to Havelockia Pearson within the Sclerodactylinae, while one species is regarded as a synonym of H. herdmani Pearson. In addition, six species are transferred to Stolus Selenka within the Thyoninae. Finally, three species are transferred to Sclerothyoninae, two within Sclerothyone Thandar and one within Temparena Thandar. Two species show an uncertain affinity to Thyone and are temporally removed from the genus. Furthermore, two species currently classified within Havelockia are transferred to Thyone. The now remaining 46 species are separated into seven groups based on the composition of their introvert deposits: tables only (8 spp.), rosettes only (5 spp.), tables and rosettes (21 spp.), tables and plates/?reduced tables (2 spp.), rosettes and plates/?reduced tables (3 spp.), plates only (2 spp.), or introvert deposits absent or unknown (5 spp.). Regrettably, no other character could be used in conjunction with the above to suggest at least sub-generic levels. Within the genus Havelockia, Cucumaria redimita Sluiter indicates an affinity with Pentamera Ayres. It is here transferred to this genus within the Thyoninae. Havelockia, now containing 17 species, is also revised. Keys, diagnoses and figures are provided for all nominal species now included in Thyone and Havelockia.
