Paleontologists have retrieved ancient enamel protein sequences from a fossilized tooth of Epiaceratherium sp., a rhinocerotid that lived in Canada’s...
A partial skeleton found in the Fernie Formation in British Columbia, Canada, back in 1916 represents a new genus and species of an extinct marine reptile...
Paleontologists have found evidence of a previously unrecognized soft tissue structure in the cheek region of many dinosaur species, which they’ve called...
