Umoonasaurus was a small, crested marine reptile that swam in cold seas near Antarctica about 115 million years ago. It had three bony crests on its head, like a tiny underwater dinosaur, but it was actually a plesiosaur, not a dinosaur. Its fossils are famous because they are preserved in beautiful blue opal.12

Makambo ya kosepelisa

1

Umoonasaurus is known from several partial skeletons, and one of them is the most complete opalized vertebrate fossil ever found.1

2

It had three thin, blade-like crests on its skull: one along the top of its snout and a pair above its eyes. These crests may have been used for display, like a peacock's tail.1

3

Umoonasaurus lived in a cold, high-latitude inland sea near the South Pole, where water temperatures were near freezing.12

4

It was a small plesiosaur, only about 2.5 metres (8 feet) long as an adult. A juvenile specimen was less than 1 metre long.1

5

Umoonasaurus is the most primitive and also the last surviving member of its group, the rhomaleosaurids. It lived about 115 million years ago.12

6

Its tail ended in a 'pygostyle-like' structure made of fused vertebrae, similar to the tail tip of some modern birds.1

Mituna oyo batunaka mingi na ntina na Umoonasaurus

?What did Umoonasaurus eat?

Umoonasaurus ate small fish. Preserved gut contents show it ate small teleost fish.1

?Why did Umoonasaurus have crests?

Scientists think the three crests on its skull were used for display, like a peacock's tail, to help recognise each other or attract mates. They were too fragile for fighting.1

?Was Umoonasaurus a dinosaur?

No, Umoonasaurus was a plesiosaur, a type of marine reptile with four flippers. It was not a dinosaur.341

Ntango bamonaki yango
Umoonasaurus was named in 2006 by Benjamin Kear and colleagues. The holotype skeleton, nicknamed 'Eric', was bought by public donations and is preserved in opal from the Zorba Extension Opal Field near Coober Pedy, Australia.1

Scientists are not sure what the three crests on its head were used for. They were too fragile for fighting, so they might have been for display or recognizing other Umoonasaurus.1
