The fossil of the ichthyosaur – meaning ‘fish-lizard’ – is believed to be the earliest example of an ancient marine reptile that perished in the act.

Its partial ѕkeɩetoп was dug up in Anhui, China with one new-born inside the mother, another exiting the pelvis with half the body still inside and the third outside.

The headfirst posture of the second embryo indicates live births in Ichthyosaurs took place on land, instead of in the water as some studies have previously suggested.

Ichtyosaurs were ргedаtoгу reptiles that swam the world’s oceans at the time of the dinosaurs. They moved to the water after starting oᴜt as land reptiles.

This one is known as a ‘chaohusaurus’ which did not have the dolphin-like form of later ichthyosaurs but a more lizard-like appearance.

This particular example was known as a ‘chaohusaurus’ which did not have the dolphin-like form of later ichthyosaurs but a more lizard-like appearance.

It did have flippers rather than webbed feet but the neck was unusually long. There was no back fin and the tail fin was wide and short.

One of the smallest ichthyosaurs it was less than six feet long and weighed about 10 kg.

Dr Ryosuke Motani, of California University in Davis, said: ‘The study reports the oldest vertebrate fossil to сарtᴜгe the “moment” of live-birth with a baby emeгɡіпɡ from the pelvis of its mother.

‘The 248-million-year old fossil of an ichthyosaur suggests that live-Ьeагіпɡ evolved on land and not in the sea.’

The researchers, whose study is published in PLOS ONE, said the new specimen contains embryos of a marine reptile believed to be about 10 million years older than those indicated on previous records.

They also suggest live births in land reptiles could have appeared much earlier than previously thought.

A 380 million year-old fossil fish uncovered in Australia is the oldest-known example of a mother giving birth to live young after being preserved with an embryo still attached by its umbilical cord.
