Theropod Metacarpal, Alberta (disposition #001590)

This is a partial metacarpal or phalanx from an unidentified theropod dinosaur. These bones helped make up the individual digits in the dinosaur's hand or wrist. Theropod bones, like a modern bird's, are commonly hollow which make them delicate and less likely to survive the ravages of geologic time. Finding partial theropod phalanges are uncommon, never mind complete ones. Unfortunately this specimen is absent the proximal end of the phalanx but has preserved the distal end, which is a lot more interesting.

The specimen’s most distinctive features are its rounded articular contours and the pronounced depression on the side of the joint end. These anatomical details remain clearly visible despite the missing shaft, offering a closer look at the structure of a dinosaur’s hand. 

Part of the Harvey Negrich Collection, this specimen combines recognizable joint anatomy with established collection provenance. Its preserved three-dimensional form makes it an interesting addition to an Alberta dinosaur collection or a display exploring dinosaur skeletal anatomy.
