Angolasaurus was one of the few Turonian mosasaurs found on both sides of the Atlantic Ocean, showing it could cross the sea.1

Its skull had 11 teeth in the upper jaw, 4 in the front, and 12 in the lower jaw.1

Scientists think Angolasaurus had a tail fluke, like a shark, for powerful swimming.1

Its body was covered in keeled scales that helped it move smoothly through water.1

Because the seas it lived in were cooling, Angolasaurus may have had dark patterns on its back to soak up heat from the sun.1

Angolasaurus shared its home in Angola with the giant mosasaur Tylosaurus and a turtle called Angolachelys.1

ርኽበት: Angolasaurus was first named in 1964 by Miguel Telles Antunes, based on a partial skull and skeleton found in Angola. It was later thought to be a species of Platecarpus, but new studies in 2005 showed it was a separate genus.1
ገና ዘከራኽር: Scientists are still debating exactly where Angolasaurus fits in the mosasaur family tree, with some studies placing it as a basal plioplatecarpine.1
