Hadrosaurus Eggs

Hadrosaurus These creatures were a plant-eating Dinosaur that lived during the Cretaceous period approx. 150 million years ago.

They were called "duck-billed" due to the fact that the skull and jaw was of a bird-like shape, with a toothless bill, but they did have cheek teeth.

In size they were approximately 23-32 feet, or 7-10 metres, long, attaining a height of around 10 feet, or 3 metres, and weighed approximately 7 tonnes.

It was likely to be bipedal for the purpose of running but could use its shorter forelegs to support itself whilst grazing. They could also swim.

They were named "Hadrosaurus" by paleontologist J. Leidy who found a skeleton in Haddonfield, New Jersey, USA (this is now the state fossil of New Jersey). In 1858 this became the first ever mounted dinosaur skeleton. Hadrosaurus Egg

Hadrosaurus laid their eggs in nests. Often the fossil includes the actual nest material as well as the egg, or eggs.

The origin of the eggs in my collection are, in this instance, China.

The better examples retain their distinctive "duck egg" blue colouring.
