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

A fossil vertebral centrum attributed to a hadrosaur, or duck-billed dinosaur, from Alberta. Measuring 5 × 5 × 4 cm, this specimen preserves the substantial central body of a vertebra.

Its relatively short, broad proportions suggest it may represent a caudal vertebra from the tail, although its precise position cannot be confirmed from the preserved features. Much of the neural arch and projecting processes is missing, leaving the centrum as the principal preserved element. I am not sure the cause of the pitting seen on one of circular faces; these could be evidence of bone disease, scavenging or simply from erosion.

From the Harvey Negrich Collection, this compact fossil combines recognizable backbone anatomy with collection provenance, making it an engaging addition to an Alberta dinosaur collection or comparative skeletal display.
