Ancient reptile's birth fossilised

A rare fossil has revealed how marine reptiles evolved to give birth to live young, scientists say.

The fossilised Chaohusaurus was discovered in central China's Anhui Province and includes the remains of three babies.

The animals lived 248 million years ago and are the earliest of the marine reptiles from the Mesozoic Era.

Experts suggest the position of the babies shows that giving birth to live young evolved on land, not in the sea.

The findings were published in the journal PLoS One.
