Ichthyosaur (Female Stenopterygius quadriscissus with foetuses)

Jurassic, 180 million years old, Holzmaden, Germany

The dolphin-like ichthyosaurs were marine reptiles that evolved 245 million years ago and became extinct before the dinosaurs, about 90 million years ago. This ichthyosaur probably died before giving birth. The foetuses were pressed out from the corpse by gas development.
