A specimen-level phylogenetic analysis and taxonomic revision of Diplodocidae (Dinosauria, Sauropoda)
TLDR
The use of a specimen-, rather than species-based approach increases knowledge of intraspecific and intrageneric variation in diplodocids, and the study demonstrates how specimen-based phylogenetic analysis is a valuable tool in sauropod taxonomy, and potentially in paleontology and taxonomy as a whole.
A new pliosaurid (Sauropterygia, Plesiosauria) from the Oxford Clay Formation (Middle Jurassic, Callovian) of England: evidence for a gracile, longirostrine grade of Early-Middle Jurassic pliosaurids
A partial skeleton from the Sigiloceras enodatum ammonite Subzone (lower Callovian, Middle Jurassic) of the Oxford Clay Formation of Quest Pit, near Stewartby, Bedfordshire, UK, represents one of the
Extinction of fish-shaped marine reptiles associated with reduced evolutionary rates and global environmental volatility
TLDR
It is shown that ichthyosaurs maintained high but diminishing richness and disparity throughout the Early Cretaceous, and that global environmental change resulted in a major, temporally staggered turnover event that profoundly reorganized marine ecosystems during the Cenomanian.
A New Elasmosaurid (Sauropterygia, Plesiosauria) from the Bearpaw Shale (Late Cretaceous, Maastrichtian) of Montana Demonstrates Multiple Evolutionary Reductions of Neck Length Within Elasmosauridae
ABSTRACT Plesiosauria is a diverse clade of marine reptiles that have been studied since the early 19th century. However, phylogenetic relationships within the group have been contentious due to
Peculiar macrophagous adaptations in a new Cretaceous pliosaurid
TLDR
It is indicated that Early Cretaceous marine reptile teeth with serrated carinae cannot be unequivocally assigned to metriorhynchoid crocodylomorphs and the known diversity of dental adaptations seen in Sauropterygia, the longest lived clade of marine tetrapods are extended.
Osteology of Huabeisaurus allocotus (Sauropoda: Titanosauriformes) from the Upper Cretaceous of China
TLDR
A detailed redescription of Huabeisaurus allocotus is presented and a suite of anatomical comparisons with other titanosauriforms that demonstrate its validity via autapomorphies are presented, suggesting that euhelopodids exemplified a comparably broad range of feeding strategies and perhaps diets.
Virtual reconstruction of the endocranial anatomy of the early Jurassic marine crocodylomorph Pelagosaurus typus (Thalattosuchia)
TLDR
Using µCT data to virtually reconstruct the endocranial anatomy of Pelagosaurus typus indicates that physiological and sensory adaptations to marine life occurred early in thalattosuchian evolution, predating the origins of flippers, tail flukes, and hydrodynamic body forms seen later in metriorhynchoids.
A redescription ofOrovenator mayorum(Sauropsida, Diapsida) using high‐resolution μCT, and the consequences for early amniote phylogeny
TLDR
The earliest known neodiapsid Orovenator mayorum from the lower Permian of Oklahoma is redescribed using high‐resolution μCT, revealing remarkable details of the skull anatomy and prompting questions about relationships among early amniotes.
Rates of dinosaur limb evolution provide evidence for exceptional radiation in Mesozoic birds
TLDR
A Cretaceous adaptive radiation of stem-group birds was enabled by restructuring of the terrestrial locomotor module, which represents a key innovation and illustrates the importance of fossil data for understanding the macroevolutionary processes generating modern biodiversity.
