(Web Desk) - The world’s oldest known crocodile eggs laid some 152 million years ago have been discovered in the cliffs of Portugal.

The eggs were found over a number of years during excavations of a dinosaur nest near the village of Lourinha, north of Lisbon.

They were found in several clutches and appear to be of two different types.

“The fact that they are from the Late Jurassic makes these eggs the oldest crocodilian eggs known so far,” said Joao Russo of Universidade Nova de Lisboa, Portugal.

The well preserved eggs give an insight into the “mother croc” that laid them, researchers said.

Palaeontologists say the prehistoric crocodile ancestor would have spanned two metres, based on the size of the larger eggs.

They are similar to the eggs of modern crocodiles, suggesting crocodile eggs have changed little in shape in the last 150 million years.
