Hadrosaur Vertebra Centrum (Tail Vertebra), Alberta (disposition #001590)

A fossil vertebral centrum from a hadrosaur, or duck-billed dinosaur, measuring 5 × 5 × 4 cm. The centrum is the substantial central body of a vertebra that articulated with neighbouring vertebrae to form the backbone.

This specimen preserves a compact, spool-like form, with broad articular ends and a narrower middle section. The photographs show the contours of both ends, together with a groove along the upper surface where the neural arch would have been situated. The neural arch and projecting processes are largely missing.

From the Harvey Negrich Collection, this specimen offers a recognizable example of dinosaur backbone anatomy. Its three-dimensional form and clearly defined vertebral contours make it an engaging addition to an Alberta fossil collection or comparative skeletal display.
