Troodon formosus – Dinosaur Nest
Late Cretaceous
Central Asia (Mongolia ?)

This outstanding dinosaur nest from the Late Cretaceous of Central Asia is among the rarest fossils to ever be auctioned. As the maximum number of eggs in a Troodon nest was thought to be 24, at 34 eggs it also represents the largest nest of its kind in existence.

The nest measures 35 centimetres by 42 centimetres at its widest points. The average length of the eggs is 10.5 centimetres and the average circumference of the eggs is 11.5 centimetres. The greyish shell is smooth and thin by comparison with other carnivores. The majority of Troodon eggs found to date exist as collections of small circles of crushed shell. These eggs were found largely intact. They have been meticulously restored and prepared by a leading expert in the field of dinosaur and reptile egg and embryo preparation.

Troodon, meaning ‘wounding tooth’, was named on the basis of a single tooth by Joseph Leidy in the 19th century. Its fossils are among the rarest and most highly prized of dinosaur finds. A sleek and agile predator, its mouth contained the largest number of razor sharp teeth of any known dinosaur. It is considered the ultimate expression of the Raptor family, with large forward facing eyes, retractable slicing toe claws, and the largest brain to body ratio in the dinosaur kingdom. Paleontologists suspect that it was a nocturnal hunter that attacked its prey in packs. It was perhaps the most bird like of all dinosaurs and is often illustrated with feathers. Troodon is known from only two locations in the world; Western North America and Central Asia.

The attached photos were taken during preparation and upon completion of the nest. The nest was recently featured in the September IM Chait Natural History Auction in Los Angeles. Though it appears there are 39 eggs in total, 5 of these eggs are the tops of hatched specimens. For comparison, a large 22 egg nest is on display at The Museum of the Rockies in Bozeman, Montana.
