They were used to decorate the formal gardens of the royal residence at Versailles, especially l’Encelade, Les Trois Fontaines and La Salle de Bal. Elsewhere, they were treasured in Song Dynasty China (960-1127 AD). In the 20th century, natural forms inspired the sculptor Henry Moore and others. -

Fossil Hadrosaur Dinosaur Nest Egg Pair
Cretaceous Period, 145-65 million years B.P.Sold for (Inc. bp): £1,430
A pair of Charonosaurus sp. hadrosaur eggs on a matrix retaining evidence of the original leathery surface. 7.6 kg total, 26 x 14 cm
From a Lincolnshire, UK, collection, 1990s. Property of a Cambridgeshire gentleman.
Dinosaur eggs are known from about 200 sites around the world, the majority in Asia and mostly in terrestrial (non-marine) rocks of the Cretaceous Period. It may be that thick calcite eggshells evolved during the Cretaceous (145 to 65 million years ago). Most dinosaur eggs have one of two forms of eggshell that are distinct from the shells of related modern animal groups, such as turtles or birds; however, some eggs closely resemble the type of shells seen in present day ostrich eggs.
