More integrated brains in crown birds evolved through a mosaic assembly of new evolutionary and developmental dynamics across neuroanatomical regions that occurred along the dinosaur-bird transition.

A specialized conduction pathway for the electrical impulse in the heart, previously thought to be associated with the endothermic mammals and birds only, is also present in the ectothermic crocodiles.

A new specimen of Heterodontosaurus elucidates how ornithischian dinosaurs evolved a body plan substantially different from that of other dinosaurs and what these differences meant for their breathing.

In-silico modeling of gene and protein emergence reveals how colony-stimulating factors contributed to the evolution and functional adaptions observed in mammalian neutrophils.

A digital flesh model of the sail-backed dinosaur Spinosaurus was tested and performed very poorly in water, favoring the view of this dinosaur as a two-legged, wading ambush predator of large fish in shallow waterways and not an aquatic dinosaur.

A complex pelvic morphology has been discovered in the fossils of one of the largest crocodylians.

The giant caiman Purussaurus from the Miocene of Venezuela is the first recorded member of crown Crocodylia having three sacrals, thus breaking the otherwise strict vertebral constraint of the group.
