“…Emys trionychoides is based on a posterior carapacial fragment depicted in visceral view consisting of the last pair of costals, the last two pairs of peripherals, the two suprapygals, the pygal, and, anteriorly, a single m e d i a n e l e m e n t t h a t m a y c o r re s p o n d t o t h e "intermediate element" of Anquetin, Püntener and BillonBruyat (2014). As noted by Cuvier (1824), the last costals contact one another medially, a character that is known to vary intraspecifically at least in Plesiochelys etalloni, Plesiochelys bigleri, and Craspedochelys jaccardi Püntener et al 2017). Rütimeyer (1873a) referred this specimen to Plesiochelys solodurensis, but he was apparently unaware of the name Emys trionychoides.…”

“…Thanks to the work of Kuhn (1964b), we were able to track down the taxonomic history of a series of five species typified in the early 1830s based on material from Solothurn, Switzerland, namely, Emys hugi Gray, 1831, Emys hugii Gray, 1831, Emys trionychoides Gray, 1831, Emys jurensis Keferstein, 1834, and Clemmys? grayi Fitzinger, 1835. Cuvier (1824 identified three distinct species in the Solothurn material sent to him by F.J. Hugi.…”

“…grayi as a substitute name for Emys hugi, perhaps because he felt it confusing to have two similarly-spelt turtle species from the same locality. These taxa were described by their respective authors along POSTPRINT with a specific reference to specimens described and figured by Cuvier (1824), which means that they are all available names. Some of these, notably Emys hugi, had the potential to alter currently established taxonomy.…”

“…These were collected by Franz Joseph Hugi, who eventually sold his collection to the city and was appointed as first director to the new city museum (Meyer and Thüring 2009). Hugi sent information and specimens to Georges Cuvier in Paris, and some of these were figured in the second edition of his Recherches sur les ossemens fossiles (Cuvier 1824;Bräm 1965;. These figured specimens were given various names during the 1830s (Gray 1831;Keferstein 1834;Fitzinger 1835), but these are now nomina oblita.…”

POSTPRINTThis is a postprint of the following peer-reviewed publication: AbstractThe Late Jurassic (Oxfordian to Tithonian) fossil record of Europe and South America has yielded a particularly rich assemblage of aquatic pan-cryptodiran turtles that are herein tentatively hypothesized to form a monophyletic group named Thalassochelydia. Thalassochelydians were traditionally referred to three families, Eurysternidae, Plesiochelyidae, and Thalassemydidae, but the current understanding of phylogenetic relationships is insufficient to support the monophyly of either group. Given their pervasive usage in the literature, however, these three names are herein retained informally. Relationships with marine turtles from the Cretaceous have been suggested in the past, but these hypotheses still lack strong character support. Thalassochelydians are universally found in near-shore marine sediments and show adaptations to aquatic habitats, but isotopic evidence hints at a broad spectrum of specializations ranging from freshwater aquatic to fully marine. A taxonomic review of the group concludes that of 68 named taxa, 27 are nomina valida, 18 are nomina invalida, 18 are nomina dubia, and 5 nomina oblita.

“…However, the taxon is distinctive enough, whether considered to be a species or subspecies, that its extinction is certain. The lost skull was originally described and pictured by Cuvier (1824), the big specimen in its whole described and named by Duméril and Bibron (1835); the same authors only briefly alluded to the young specimen. A tentative study of the DNA of both specimens failed (Austin and Arnold 2001;Gerlach 2004Gerlach , 2014.…”

ABsTrAcT. -We provide a first checklist and review of all recognized taxa of the world's extinct Pleistocene and Holocene (Quaternary) turtles and tortoises that existed during the early rise and global expansion of humanity, and most likely went extinct through a combination of earlier hominin (e.g., Homo erectus, H. neanderthalensis) and later human (H. sapiens) exploitation, as well as being affected by concurrent global or regional climatic and habitat changes. This checklist complements the broader listing of all modern and extant turtles and tortoises by the Turtle Taxonomy Working Group (2014). We provide a comprehensive listing of taxonomy, names, synonymies, and stratigraphic distribution of all chelonian taxa that have gone extinct from approximately the boundary between the Late Pliocene and Early Pleistocene, ca. 2.6 million years ago, up through 1500 AD, at the beginning of modern times. We also provide details on modern turtle and tortoise taxa that have gone extinct since 1500 AD. This checklist currently includes 100 fossil turtle and tortoise taxa, including 84 named and apparently distinct species, and 16 additional taxa that appear to represent additional valid species, but are only identified to genus or family. Modern extinct turtles and tortoises include 8 species, 3 subspecies, and 1 unnamed taxon, for 12 taxa. Of the extinct fossil taxa, terrestrial tortoises of the family Testudinidae (including many large-bodied island forms) are the most numerous, with 60 taxa. When the numbers for fossil tortoises are combined with the 61 modern (living and extinct) species of tortoises, of the 121 tortoise species that have existed at some point since the beginning of the Pleistocene, 69 (57.0%) have gone extinct. This likely reflects the high vulnerability of these large and slow terrestrial (often insular) species primarily to human exploitation. The other large-bodied terrestrial turtles, the 000e.2 Conservation Biology of Freshwater Turtles and Tortoises • Chelonian Research Monographs, No. 5As an addition to the annual checklist of extant modern turtle taxa (Turtle Taxonomy Working Group [TTWG] 2014), we here present an annotated checklist of extinct Pleistocene and Holocene turtle and tortoise species that existed in relatively recent times, prior to 1500 AD, during the history of the rise and global spread of humanity and concurrent global climatic and habitat changes. These species, recorded from archaeological and paleontological sites from the Pleistocene and Holocene epochs (Quaternary period), approximately the last 2.6 million years, are currently considered to be valid, and not synonymous with modern (post-1500 AD) taxa.These fossil species, including some unnamed taxa of indeterminate or undescribed generic or specific allocation, represent the majority of the chelonian diversity that has gone extinct relatively recently. Many of these taxa were likely extirpated by anthropogenic exploitation over the relatively long prehistory of earlier hominin (e.g., Homo erectus, H. neanderthalensi...

Cranial and endocranial anatomy of a three‐dimensionally preserved teleosauroid thalattosuchian skull

Thalattosuchians represent one of the several independent transitions into the marine realm among crocodylomorphs. The extent of their aquatic adaptations ranges from the semiaquatic teleosauroids, superficially resembling extant gharials, to the almost cetacean‐like pelagic metriorhynchids. Understanding the suite of osteological, physiological, and sensory changes that accompanied this major transition has received increased attention, but is somewhat hindered by a dearth of complete three‐dimensionally preserved crania. Here, we describe the cranial and endocranial anatomy of a well‐preserved three‐dimensional specimen of Macrospondylus bollensis from the Toarcian of Yorkshire, UK. The trigeminal fossa contains two similar‐sized openings separated by a thin lamina of prootic, a configuration that appears unique to a subset of teleosauroids. Macrospondylus bollensis resembles other thalattosuchians in having pyramidal semicircular canals with elongate cochlear ducts, enlarged carotid canals leading to an enlarged pituitary fossa, enlarged orbital arteries, enlarged endocranial venous sinuses, reduced pharyngotympanic sinuses, and a relatively straight brain with a hemispherical cerebral expansion. We describe for the first time the olfactory region and paranasal sinuses of a teleosauroid. A relatively large olfactory region suggests greater capacity for airborne olfaction in teleosauroids than in the more aquatically adapted metriorhynchoids. Additionally, slight swellings in the olfactory region suggest the presence of small salt glands of lower secretory capacity than those of metriorhynchoids. The presence of osteological correlates for salt glands in a teleosauroid corroborates previous hypotheses that these glands originated in the common ancestor of Thalattosuchia, facilitating their rapid radiation into the marine realm.
