Abstract Plastomenidae is a poorly diagnosed clade of extinct soft-shelled turtles (Trionychidae) known from the Campanian to Eocene of North America. Five skulls, a mandible, two carapaces, and numerous plastral remains from the Hell Creek Formation (Late Cretaceous, Maastrichtian) of North Dakota and Montana are referable to Gilmoremys lancensis nov. comb., a taxon previously known from a carapace and xiphiplastron only. Gilmoremys lancensis is diagnosed by a carapace that is covered by… 
New Cranial Material of Gilmoremys lancensis (Testudines, Trionychidae) from the Hell Creek Formation of Southeastern Montana, U.S.A.
ABSTRACT Plastomenidae is a speciose clade of soft-shelled turtles (Trionychidae) known from Campanian to Eocene deposits throughout western North America. We here describe two large skulls from
A new species of trionychid turtle, Axestemys infernalis sp. nov., from the Late Cretaceous (Maastrichtian) Hell Creek and Lance formations of the Northern Great Plains, USA
TLDR
A new species of trionychid is described, Axestemys infernalis sp.
A New Baenid Turtle, Saxochelys gilberti, gen. et sp. nov., from the Uppermost Cretaceous (Maastrichtian) Hell Creek Formation: Sexual Dimorphism and Spatial Niche Partitioning within the Most Speciose Group of Late Cretaceous Turtles
ABSTRACT The uppermost Cretaceous (Maastrichtian) Hell Creek Formation in North America has yielded a diverse assemblage of fossil turtles dominated by baenids. A population of over 30 individual
A New Soft-Shelled Trionychid Turtle of the Genus Khunnuchelys from the Upper Cretaceous Bostobe Formation of Kazakhstan
Previously unpublished trionychid turtle material from the Upper Cretaceous (Santonian—lower Campanian) Bostobe Formation from the Baybishe and Baykhozha localities in Kazakhstan is described. The
The shell morphology of the latest Cretaceous (Maastrichtian) trionychid turtle Helopanoplia distincta
TLDR
Shell remains of eight fossils referable to Helopanoplia distincta from the Hell Creek Formation of Montana and North Dakota are described that document nearly all aspects of the shell morphology of this taxon and place it as sister to the clade formed by Plastomenus thomasii and Hutchemys spp.
A new plastomenid trionychid (Testudines: Pan-Trionychidae) from Milk River Formation of southern Alberta (Cretaceous: Santonian)
TLDR
A new species of plastomenid soft-shelled turtle is described based on a partial shell from the Santonian Milk River Formation of southern Alberta, estimated at approximately 84 Ma, which represents the oldest relatively complete shell of a trionychid from North America.
A new baenid turtle from the early Paleocene (Torrejonian) of New Mexico and a species-level phylogenetic analysis of Baenidae
TLDR
A nearly complete species-level analysis of baenids confirms the basal placement of Neurankylus outside of Baenodda and the split of Baensodda into two primary subclades, herein named Palatobaeninee and Eubaeninae.
A New Plastomenid Trionychid Turtle, Plastomenus joycei, sp. nov., from the Earliest Paleocene (Danian) Denver Formation of South-Central Colorado, U.S.A.
ABSTRACT North American soft-shelled turtles, including trionychines and plastomenids, are incredibly abundant in latest Cretaceous through earliest Paleocene sediments. Here we describe a new
A NEW SPECIES OF SOFT-SHELLED TURTLE ( TRIONYCHIDAE ) FROM THE MIDDLE EOCENE OF UKRAINE
TLDR
T. ikoviensis is the easternmost representative of Trionyx sensu lato (sensu Lapparent de Broin 2001) and represents the first discovery of a trionychid skull in the Cenozoic deposits of the Ukraine in particular and the best discovery of this kind from the Censozoic of the former USSR in general.
Palaeoamyda messeliana nov. comb. (Testudines, Pan-Trionychidae) from the Eocene Messel Pit and Geiseltal localities, Germany, taxonomic and phylogenetic insights
TLDR
A revised diagnosis for the species is presented here, together with its inclusion in a phylogenetic analysis of Pan-Trionychidae that shows that this species is sister to the extant Amyda cartilaginea, one of the most abundant pan-trionyblade turtles from Asia, both members of the clade Chitrini.

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.
Two New Plastomenine Softshell Turtles from the Paleocene of Montana and Wyoming
TLDR
A phylogenetic analysis places the new species of plastomenine softshell turtles (Trionychidae) that are referred to Hutchemys gen. nov in a clade that is sister to Plastomenus aff.
New soft-shelled turtles (Plastomeninae, Trionychidae, Testudines) from the Late Cretaceous and Paleocene of North America
Two new genera (Derrisemys and Plastomenoides) and three new species (D. sterea, P. lamberti, P. tetanetron) of plastomenine trionychids from Montana and Wyoming are described. They are unique within
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.
Cranial Anatomy and Phylogenetic Placement of the Enigmatic Turtle Compsemys victa Leidy, 1856
TLDR
Taphonomic evidence reveals that basal paracryptodires, including C. victa, preferred slow moving or ponded water environments, and the riverine habitat preference of baenodds must therefore be derived.
A Revision of Plesiobaena (Testudines: Baenidae) and an Assessment of Baenid Ecology Across the K/T Boundary
TLDR
The phylogenetic analysis clearly reveals that Plesiobaena in the traditional sense is a paraphyletic assemblage relative to the clade formed by Gamerabaena sonsalla and Palatobaena spp.
A neglected lineage of North American turtles fills a major gap in the fossil record
TLDR
The first phylogenetic analysis of Trionychidae that includes a representative of the poorly studied taxon Plastomenidae reveals that plastomenids are stem cyclanorbines, thus significantly reducing the apparent ghost range of total group Cyclanorbinae to approximately 30 Ma.

Multiple data sets, high homoplasy, and the phylogeny of softshell turtles (Testudines: Trionychidae).
TLDR
A strong estimate of the phylogeny of softshell turtles is used as the basis for a novel rank-free classification, and strategies for analyzing highly homoplasious mtDNA data in deep phylogenetic problems where increased taxon sampling is not an option are examined.
