Stegosaurus Vertebra in Matrix

This is a vertebra from a Jurassic-era Stegosaurus, still partially embedded in its original natural matrix. It was discovered in the ancient Jurassic deposits of Wyoming, a region famous for its rich dinosaur fossil beds.

Wyoming is a treasure trove for Jurassic-era dinosaur fossils, offering a rare glimpse into a world that existed over 150 million years ago. During this time, vast floodplains and lush forests covered the region, creating the perfect environment for preserving prehistoric life. Dinosaurs like Allosaurus, Apatosaurus, Stegosaurus, and Camarasaurus once roamed these lands—massive plant-eaters and fierce predators that defined the Jurassic landscape. Many of their remains have been uncovered in formations like the Morrison, where bones, footprints, and even fossilized plants tell the story of a thriving ecosystem long before humans ever appeared.
