Modern amphibians are characterized by an aquatic larval stage that ends abruptly with a period of widespread tissue remodeling (metamorphosis) upon transition to terrestrial adulthood. A transient la...

The Triassic was a unique time for beak evolution, as seen in a wide diversity of terrestrial tetrapods. Beaks were present in dicynodont synapsid survivors of the Permo-Triassic mass extinction even...

Scientific Reports - Evolutionary stasis in synapsid encephalization during the end-permian mass extinction

The venue broke the record for the most visitors to any museum or gallery in a single year.

The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their signi...

Anatomical network analysis and morphometric methods illuminate the influences of functional adaptation and developmental constraint on the evolution of cranial form in carnivorous Permian synapsids.

The NHM Collections Study Awards provide funding for undergraduate and graduate students to visit and study the collections of the Natural History Museum of Los Angeles County, the La Brea Tar Pits & ...

The Geological Collections Group is for anyone who is interested in geological collections. Membership is open to all and is reasonably priced.

Shuvosauridae is a clade of pseudosuchian archosaurs currently represented by three named species characterized by a body plan strikingly convergent with that of ornithomimid theropod dinosaurs. Th...

Abstract. Early evolutionary history of tetrapods is typically divided into two major phases: an initial diversification of archaic stem tetrapod groups, a

The paleotropics of Euramerica provide nearly our entire picture of Permo–Carboniferous terrestrial tetrapod evolution. The geographic sampling bias inherent in this record obscures important event...

We describe a close relative of Spinosaurus aegyptiacus, the sail-backed, fish-eating giant from nearshore deposits of northern Africa. Spinosaurus mirabilis sp. nov., discovered in the central Sahara...

Gardiner et al. reconstruct the diversity of sharks and rays across the past 145 million years using deep learning and an extensive dataset. Their results unveil previously hidden patterns, including ...
