Abstract Over the course of the last two decades, the baenid taxon Plesiobaena has typically been thought to consist of two named species, Plesiobaena antiqua (Campanian) and Plesiobaena putorius (Paleocene), along with an unnamed species from the Maastrichtian, but the interrelationship of these three taxa was never explored in an explicit phylogenetic context. Herein we present or re-describe a number of relevant specimens and provide a cladistic analysis of Baenidae using species only as… 
A new European Late Jurassic pleurosternid (Testudines, Paracryptodira) and a new hypothesis of paracryptodiran phylogeny
TLDR
The new phylogenetic proposal, and its analysis in view of stratigraphical distributions, shows that Baenidae was a clade of turtles only known in the Cretaceous and Palaeogene of the North American record but that Pleurosternidae and Compsemydidae were distributed both in North America and Europe.
Boremys (Testudines, Baenidae) from the Latest Cretaceous and Early Paleocene of North Dakota: An 11-Million-Year Range Extension and an Additional K/T Survivor
ABSTRACT For over a century, the baenid turtle Boremys has been recognized as being restricted to the Campanian of North America. Herein we describe new material of Boremys sp. from the Hell Creek
Revision of the Triassic European turtles Proterochersis and Murrhardtia (Reptilia, Testudinata, Proterochersidae), with the description of new taxa from Poland and Germany
TLDR
New discovered plesiomorphic aspects of the anatomy of these three species included in the phylogenetic analysis demonstrate that they are not only the oldest, but are also the most basal fully shelled turtles.
A New Species of Baenid Turtle from the Kaiparowits Formation (Upper Cretaceous, Campanian) of Southern Utah
TLDR
New baenid turtle specimens from the middle Campanian Kaiparowits Formation of southern Utah are described herein as a new taxon, Arvinachelys goldeni, gen. et sp.
Portlandemys gracilis n. sp., a New Coastal Marine Turtle from the Late Jurassic of Porrentruy (Switzerland) and a Reconsideration of Plesiochelyid Cranial Anatomy
TLDR
The results suggest that plesiochelyids, 'Thalassemys' moseri, and Solnhofia parsonsi (representing the Eurysternidae) form a clade at the base of Eucryptodira.
Baenid turtles of the Kaiparowits Formation (Upper Cretaceous: Campanian) of southern Utah, USA
I describe the assemblage of baenid turtles found in the Campanian Kaiparowits Formation of southern Utah and compare it with baenids from other basins across Laramidia. Baenids were one of the most
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.
Morphological variation, phylogenetic relationships, and geographic distribution of the Baenidae (Testudines), based on new specimens from the Uinta Formation (Uinta Basin), Utah (USA)
TLDR
New baenids from the Uintan NALMA provide valuable insight into the morphology and evolution of the diverse and speciose baenid family near the end of its extensive radiation, just prior to the disappearance of this clade from the fossil record.
Morphology and Relationships of Brachyopsemys tingitana gen. et sp. nov. from the Early Paleocene of Morocco and Recognition of the New Eucryptodiran Turtle Family: Sandownidae
The first cryptodiran turtle with a pitted palate, Brachyopsemys tingitana gen. et sp. nov., is described on the basis of skulls and a lower jaw from the early Paleocene (Danian) of the Ouled Abdoun

A New Species of Palatobaena (Testudines: Baenidae) and a Maximum Parsimony and Bayesian Phylogenetic Analysis of Baenidae
TLDR
The baenid topology reveals a demonstrably homoplastic trend towards the reduction of the temporal emargination and unique thickening of the posterior portion of the parietals that corresponds with the K/T boundary and is hypothesized to have provided limited protection from increasingly effective mammalian predators.
A New Baenid Turtle from the Upper Cretaceous (Maastrichtian) Hell Creek Formation of North Dakota and a Preliminary Taxonomic Review of Cretaceous Baenidae
TLDR
A fragmentary skull from the Hell Creek Formation of southwestern North Dakota represents a new taxon of baenid turtle named herein Gamerabaena sonsalla, which has several morphological features that are intermediate between Plesiobaena antiqua and the morphologically disparate Palatobaena spp.
ANATOMY AND SYSTEMATICS OF PLESIOBAENA ANTIQUA (TESTUDINES; BAENIDAE) FROM THE MID-CAMPANIAN JUDITH RIVER GROUP OF ALBERTA, CANADA
TLDR
New material from the mid-Campanian Judith River Group of Alberta, Canada, fully documents the skeleton in this species and provides evidence regarding variation within the taxon, suggesting that it was a member of a northern faunal assemblage.
Phylogenetic Relationships of Mesozoic Turtles
TLDR
This revised topology has important implications for the evolution of several character complexes, because it implies that the common ancestor of all living turtles must have had a partially braced brain case and a primitive trochlear mechanism.
Bivalves : an eon of evolution : paleobiological studies honoring Norman D. Newell
Since their origin in the Early Cambrian, the bivalve molluscs have evolved a remarkable variety of forms that reflect their diverse habits through the Phanerozoic Eon. The thirty papers in this
Anatomy and relationships of the turtle Boremys pulchra (Testudines: Baenidae)
TLDR
It is concluded that the derived characters of the carapace and plastron that had previously defined the Eubaeninae but are not present in Boremys have arisen independently within the subfamily.
Rhinochelys (Chelonioidea: Protostegidae) from the Late Cretaceous (Cenomanian) of Nammoura, Lebanon
TLDR
Despite a very large ulnare, the front flipper of protostegids appears to retain the primitive digit configuration of chelonioids, in the relative length of the digits andphalanges and in the absence of reduction of the number of phalanges.
Late Cretaceous and early Paleocene turtles of the Denver Basin, Colorado
The record of turtles in the Denver Basin spans four formations (Fox Hills, Laramie, Arapahoe, and Denver) that range from Late Cretaceous (Lancian) to early Paleocene (Puercan) in age. We recognize
A NEW EUBAENINE, GOLEREMYS MCKENNAI, GEN. ET SP. N., (BAENIDAE: TESTUDINES) FROM THE PALEOCENE OF CALIFORNIA
TLDR
The skull of a new turtle from the Tiffanian (Paleocene) of the Goler Formation, Kern County, California is the first confirmed baenid from the Pacific slope of North America and appears to be the sister taxon of those eubaenine genera.
The skull of Neurankylus eximius (Testudines: Baenidae) and a reinterpretation of the relationships of this taxon
TLDR
The skull of the primitive baenid turtle Neurankylus demonstrates that it is distinct from Hayemys and is a primitive relative to the Baenodd, which is a monophyletic taxon including Baenidae and Pleurosternidae.
