Check the listing for details. Hadrosaur Embryonic Skeleton Cast With Egg Shell-.... Condition: New. Listed at 49.99 USD. This a resin cast of the embryonic skeleton from the Cretaceous Hadrosaur Parasaurolophus walkeri. My cast replicas are created from natural fossils ( not sculptures or 3D printed items) using an eco friendly plant based mold making material that is reusable. Made to order so items may differ from the image of the listing. Items are hand painted where appropriate and sealed with a clear coat finish. This adds to the texture in addition to preserving the paint job, for example the shiny enamel of a megalodon tooth cast is achieved this way. However, it may be accompanied with a paint thinner like smell. I've only had this complained about once, but if this is the case please wash item with soap and water and allow to sit outside for the smell to subside. These replicas are much more durable than a standard museum display piece and can withstand abuse, making them ideal for children or for a variety of uses. For example, during a demonstration I threw an allosaurus claw against a concrete floor and the thing just bounced off, sustaining no noticeable damage. Colors may vary depending on availability of coloring agents.
