Virtual investigation of the 3.67-million-year-old skull of 'Little Foot' using synchrotron radiation reveals histological details of Australopithecus dental and bone tissues.

Teeth and dermal odontodes diverge from the same set of founder odontodes, demonstrating they are modified subsets of the same system, and both oral and dermal epithelial have patterning capacity.

Fossilized feces (coprolites) of extinct bone-crushing dogs, Borophagus parvus, from late Miocene (6 million years ago) of California demonstrates consumption and preservation of bones in digestive tracts and potential social hunting behavior by these predators.

The tooth shape of sharks and mice are regulated by a similar signaling center despite their teeth having very different geometries.

Gene co-expression analysis identifies coherent transcriptional patterns driven by distinct cell types in the mouse incisor, and functional studies of candidate genes reveal how the tissues are maintained through stem cell-fueled renewal.

A new hominin species has been unearthed in the Dinaledi Chamber of the Rising Star cave system in the largest assemblage of a single species of hominins yet discovered in Africa.

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.

Experiments on mice have shown that developmental processes are influencing the generation of phenotypic variation in a way that shapes evolution.

The accumulation of ferroptotic stress during tooth development has a critical effect on its morphogenesis.

A reusable system of 3D printed stainless steel microdrive and plastic head cap allows stable recording of electrophysiological data in mice and rats and easy recovery of silicon probes.
