Date

BCE (75000000 - 86000000)

Full Description

Circa 86 - 75 million years old.

Aeons before the chicken, came the dinosaur egg.

Until the early 1900s scientists could only theorise that dinosaurs were hatched from eggs since not even a single example had ever been found. When a nest with a clutch of fossilised eggs was finally discovered in the Gobi desert of Mongolia, it was hailed as one of the most important finds in the history of palaeontology.

Dinosaur eggs were never huge in proportion to their parents as the shell would have been far too thick to hatch. These eggs probably come from the Therzinosaur, a dinosaur related to the T-Rex and date from the Cretaceous period. All have traces of the grey fossilised shell.
