Unprepared Lambeosaurus Vertebrae Fossil – Judith River Formation

This authentic Lambeosaurus vertebra fossil dates to approximately 79–75 million years ago from the Late Cretaceous period. Discovered in the Judith River Formation of Montana, this specimen comes from one of North America’s most well-known dinosaur-bearing formations.

The vertebra remains unprepared, still partially encased in its natural matrix, offering a rare opportunity to view — or even complete — the preparation process. Surface textures and visible structure provide a glimpse into the spinal anatomy of these large duck-billed dinosaurs.

Its natural, untouched state makes it especially appealing for collectors, preparators, or anyone looking for a more hands-on connection to prehistoric life.
