Dallasaurus was a small, ancient marine lizard that lived in the sea about 92 million years ago. It could walk on land too, like a modern seal, because its legs were not yet flippers.1

Dallasaurus is one of the oldest mosasaurs found in North America, living about 92 million years ago.1

It was small for a mosasaur, only about 1 meter (3.3 feet) long, much smaller than later giant mosasaurs.1

Dallasaurus had legs that could still walk on land, so it lived both in the water and on shore, like a seal.1

Its fossils were found in a housing construction site in Texas, and the site is now covered by buildings.1

The species name turneri honors amateur fossil collector Van Turner, who found the first specimen.1

Dallasaurus is a close relative of later, fully marine mosasaurs that had flippers instead of legs.3
