Hadrosaur Dinosaur Egg Cast - Museum-Quality Paleontological Reproduction

Hadrosaurs - the duck-billed dinosaurs - were among the most successful and widespread herbivores of the Late Cretaceous, forming vast herds across North America, Asia, and Europe. They are also among the best-studied dinosaur parents in the fossil record: nesting sites discovered in Montana in the 1970s revealed that hadrosaurs returned to the same nesting grounds year after year and actively cared for their young - behaviors once thought exclusive to birds and mammals. This Hadrosaur dinosaur egg cast reproduces the largest and most complete egg specimen in our source collection, presented in its own rounded, pedestal-like matrix exactly as it was found.

The Largest and Most Complete Specimen in the Collection

This duck-billed dinosaur nest paleontological cast measures 6 in L x 6 in W x 2 in H and is set in a cradle-like matrix that presents the egg as a field paleontologist would encounter it - still nestled in the surrounding material that preserved it for 75 million years. Hand-cast in compound stone in the USA and finished with an aged patina, this is - by the assessment of the source collection - a specimen of exceptional completeness. The rounded form, the surface texture of the shell, and the matrix base are all faithfully rendered.

The Hadrosaur Dinosaur Egg Cast for Display and Education

This compound stone Cretaceous egg reproduction weighs approximately 7 lbs - substantial and stable on any surface. The matrix base means it requires no stand and displays naturally in any orientation. It pairs with the Oviraptor Dinosaur Egg Cast (SK217) for a two-egg display that invites comparison between the elongated, upright Oviraptor egg and the broader, flatter Hadrosaur form - a window into the diversity of dinosaur reproductive strategies. Made in the USA.
