“…Aquatic taxa are the most conspicuous biotic elements of Gondwanan affinities in the Contamana section (charophytes, neritid gastropods and hyriid bivalves, cichlid actinopterygians, lepidosireniform lungfishes, plus chelid and podocnemidid turtles), in agreement with the conclusions of Brito et al (2007) and Sterli and de la Fuente (2013). Similarly, pipid anurans occur only in South America and Africa (recent: San Mauro et al, 2005;fossil: Rage et al, 2013).…”

“…Kawasphenodon adds to the wide array of ectotherm tetrapod lineages crossing the K/Pg boundary in Patagonia. They include calyptocephalellid and pipid frogs [27,28], 'madtsoiid' snakes [29] and meiolaniform and chelid turtles [30,31].…”

The youngest South American rhynchocephalian, a survivor of the K/Pg extinction

2014

Rhynchocephalian lepidosaurs, though once widespread worldwide, are represented today only by the tuatara ( Sphenodon ) of New Zealand. After their apparent early Cretaceous extinction in Laurasia, they survived in southern continents. In South America, they are represented by different lineages of Late Cretaceous eupropalinal forms until their disappearance by the Cretaceous/Palaeogene (K/Pg) boundary. We describe here the only unambiguous Palaeogene rhynchocephalian from South America; this new taxon is a younger species of the otherwise Late Cretaceous genus Kawasphenodon . Phylogenetic analysis confirms the allocation of the genus to the clade Opisthodontia. The new form from the Palaeogene of Central Patagonia is much smaller than Kawasphenodon expectatus from the Late Cretaceous of Northern Patagonia. The new species shows that at least one group of rhynchocephalians not related to the extant Sphenodon survived in South America beyond the K/Pg extinction event. Furthermore, it adds to other trans-K/Pg ectotherm tetrapod taxa, suggesting that the end-Cretaceous extinction affected Patagonia more benignly than the Laurasian landmasses.

“…This unnamed and vanished species was apparently the last surviving member of this most impressively distinct and ancient family of giant horned terrestrial turtles. Several recent phylogenies suggest that the Meiolaniidae branched off as a separate clade of turtles before the CryptodiraPleurodira split (e.g., Joyce 2007; Sterli and de la Fuente 2013), but others (e.g., Gaffney 1996;Gaffney et al 2007;Gaffney and Jenkins 2010) place them among the Cryptodira. In either case, their recent extinction was indeed major, not just for their disparate and bizarre morphology, but also because had they persisted, they would have been one of the most evolutionarily and phylogenetically distinct lineages of surviving chelonians-truly a monumental loss.…”

We list it here under Meiolaniformes, as recommended by Sterli and de la Fuente (2013), but the hierarchical placement in our checklist is simply intended to be functional, and does not imply specific support for, or disagreement with, either proposed phylogeny. Comment: This is the most recently extinct named taxon of Meiolaniidae, extirpated by modern humans of the Lapita culture.…”

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...
