A small caseid synapsid, Arisierpeton simplex gen. et sp. nov., from the early Permian of Oklahoma, with a discussion of synapsid diversity at the classic Richards Spur locality
Graciela Piñeiro –– The paper describes a new caseid pelycosaur from the Early Permian of Oklahoma. Caseids are one of the basalmost known synapsids having evolved herbivory and every new discovering will account for a better understanding of the evolutionary history of this group.
A new testudinoid turtle from the middle to late Eocene of Vietnam
Hans-Dieter Sues –– New species from a previously poorly sampled area; fossil sample of considerable size (probably representing a single population) showing variation in morphological features.
The Early Pliocene extinction of the mega-toothed shark Otodus megalodon: a view from the eastern North Pacific
Kenneth De Baets –– As the data have relevance to constrain the age of extinction of this now extinct giant shark - it would be relevant to ecologists, evolutionary biologist to further constrain the causes of its demise.
Integrating gross morphology and bone histology to assess skeletal maturity in early dinosauromorphs: new insights from Dromomeron (Archosauria: Dinosauromorpha)
John Hutchinson –– Along with other work ongoing by these and other authors on early archosaurian ontogenetic variation and histology, this study is shedding important light on how growth patterns evolved and how variable certain characters used in systematic analyses are. This is important insight.
Shell variability in the stem turtles Proterochersis spp.
Jérémy Anquetin –– Detailed description of morphological variability in early turtles
Ornithopod diversity in the Griman Creek Formation (Cenomanian), New South Wales, Australia
Hans-Dieter Sues –– Important records of Cretaceous ornithopod dinosaurs from Australia.
Postmortem transport in fossil and modern shelled cephalopods
Kenneth De Baets –– The manuscript introduces a new metric for drift potential of cephalopod shells relevant for paleontologist and biologists. When applying it on fossil ammonoids and modern nautilids, the author demonstrates that long post-mortem drift is more than sometimes claimed and that their geographic ranges are reasonable proxies for geographic range during life making it also of great interest to biogeographers and ecologists. The results also suggest the presence modern or recently extirpated populations of Nautilus in the Indian ocean, which is of relevance for conservation efforts.
A needle in a haystack: Mesozoic origin of parasitism in Strepsiptera revealed by first definite Cretaceous primary larva (Insecta)
Kenneth De Baets –– This article allow back to track the origin of strepsipteran parasitic lifestyle back ca. 100 million years indicating an exceptional case of evolutionary stasis.
Prionochelys matutina Zangerl, 1953 (Testudines: Pan-Cheloniidae) from the Late Cretaceous of the United States and the evolution of epithecal ossifications in marine turtles
Mark Young –– This contribution is important as it is one of a growing number of papers that is elucidating the evolution of marine turtles. Compared to other Mesozoic marine reptiles, the evolution, taxonomy and comparative anatomy of marine turtles is still poorly understood.
Cancellous bone and theropod dinosaur locomotion. Part I—an examination of cancellous bone architecture in the hindlimb bones of theropods
Mathew Wedel –– This work is legitimately groundbreaking in its scope and in its potential to move the field forward. The papers in this series seem destined to become citation classics.
