Abstract. A new species of meiolaniform turtle, Trapalcochelys sulcata gen. nov. sp. nov. is described, based on material from the late Campanian—early Maastrichtian Allen Formation, Patagonia (Argentina). The postcranial remains recovered are described macroscopically (e.g., external morphology) and microscopically (e.g., histological sections of the shell). Trap alcochelys sulcata gen. nov. sp. nov. shares with other meiolaniforms the presence of sulci strongly curved anteriorly among…

A new turtle from the Palaeogene of Patagonia (Argentina) sheds new light on the diversity and evolution of the bizarre clade of horned turtles (Meiolaniidae, Testudinata)
TLDR
A new species of horned turtle from the Paleogene of Patagonia that sheds new light on the evolution and palaeobiogeographical history of the clade Meiolaniidae in Australasia and South America during the Cainozoic is presented.

A Review of the Fossil Record of Gondwanan Turtles of the Clade Meiolaniformes

TLDR
Gondwanan turtles of the clade Meiolaniformes have a fossil record that reaches back to the Early Cretaceous of Patagonia and Australia but appears to be extirpated afterwards, while Meiolaniids appear to have been preadapted to floating across short to intermediate oceanic distances.
A toothed turtle from the Late Jurassic of China and the global biogeographic history of turtles
TLDR
A revision of the global distribution of fossil and recent turtle reveals that the three primary lineages of derived, aquatic turtles, including the crown, Paracryptodira, Pan-Pleurodira, and Pan-Cryptodira can be traced back to the Middle Jurassic of Euramerica, Gondwana, and Asia, respectively, which resulted from the primary break up of Pangaea at that time.

TLDR
Sedimentological, anatomical, and histological data universally hint at terrestrial habitat preference among the earliest stem turtles, but a more mixed, though unambiguously continental signal is apparent further towards the crown.

Re-Description and Evolutionary Remarks on the Patagonian Horned Turtle Niolamia argentina Ameghino, 1899 (Testudinata, Meiolaniidae)
TLDR
Following the preferred phylogenetic hypothesis, South American and Australian taxa related to or belonging to Meiolaniidae and Mongolochelys efremovi from the Upper Cretaceous of Mongolia form a monophyletic group, implying that the origin and diversification of this lineage predated the complete break up of Pangea in the Early to Middle Jurassic.
Chubutemys, a New Eucryptodiran Turtle from the Early Cretaceous of Argentina, and the Relationships of the Meiolaniidae
TLDR
Chubutemys copelloi is the oldest nonmarine cryptodire from South America represented by a skull and an enclosed canalis caroticus internus extending to the posterior margin of the pterygoid, showing that it is a eucryptodire.
A new species of the genus Atlantoceratodus (Dipnoiformes: Ceratodontoidei) from the Uppermost Cretaceous of Patagonia and a brief overview of fossil dipnoans from the Cretaceous and Paleogene of South America
TLDR
A new phylogenetic analysis including tooth plates and calvarian morphology has been conducted in order to evaluate the relationships among post-Paleozoic dipnoans of the clade Ceratodontoidei.
New Mammalian Remains from the Late Cretaceous La Colonia Formation, Patagonia, Argentina
TLDR
New mammalian remains collected in outcrops of the La Colonia Formation exposed in Chubut Province, Argentina are described, warranting the recognition of a new mesungulatid Coloniatherium cilinskii gen. et sp.
The parabasisphenoid complex in Mesozoic turtles and the evolution of the testudinate basicranium
During the early development of turtles and other amniotes, the parabasisphenoid, or basisphenoid s.l., is formed by at least two centers of ossification: the endochondral basisphenoid s.s. and the…
New evidence from the Palaeocene of Patagonia (Argentina) on the evolution and palaeo-biogeography of Meiolaniformes (Testudinata, new taxon name)
TLDR
The phylogenetic scenario presented here shows that at least two lineages of Meiolaniformes survived the K–P boundary extinction, and supports the hypothesis that this group of turtles may have originated as early as the Early Cretaceous in the South American part of Gondwana.
Bone histology of the Middle Jurassic turtle shell remains from Kirtlington, Oxfordshire, England
TLDR
According to the results, the stratigraphic appearance of the Pleurosternidae is adjusted from the Kimmeridgian to the Bathonian (Middle Jurassic), which significantly reduces the ghost lineage of Paracryptodira.
