Acostasaurus
Acostasaurus was a fierce marine reptile that swam in the warm seas of Colombia about 125 million years ago. It had a big head, sharp teeth, and flippers to paddle through the water. Even though it was not a dinosaur, it was a top predator in its ocean home.1

Acostasaurus had very large eye sockets and big scleral rings, which helped it see in deep or murky water.1
Its skull was short and wide in the front, unlike many other pliosaurs that had long snouts.1
The only known fossil is a nearly complete skull and parts of the body, including a whole hind flipper and many vertebrae.1
Acostasaurus lived during the Early Cretaceous, a time when few plesiosaur fossils are known, called the 'Lower Cretaceous Gap'.3
It had a short lower jaw joint area with only five and a half pairs of tooth sockets, which is unusual for a pliosaur.1
The specimen was a subadult, because some bones in its skull were not fully grown together.1

?How big was Acostasaurus?
It was over 4 metres (13 feet) long. That is about as long as a small car.1
?Was Acostasaurus a dinosaur?
No, it was a marine reptile called a pliosaur, not a dinosaur. It lived in the ocean.1
?What did Acostasaurus eat?
It was a predator that ate other sea creatures. Its sharp teeth helped it catch prey.1

- Acostasaurus was named by Marcela Gómez Pérez and Leslie F. Noè in 2011, based on a fossil found in the Paja Formation of Colombia. The species name is Acostasaurus pavachoquensis.12
- Ammallee falmisiisaa
- Scientists are not sure whether Acostasaurus belongs to the brachauchenine group of pliosaurs, because its teeth are different from theirs.1
