Hadrosaur Toe Bone (Ungual), Alberta (disposition #001590)

A hadrosaur ungual (terminal toe bone) from a duck-billed dinosaur, measuring 8 × 6.5 × 4 cm. This element occupied the end of a toe and formed the bony core of its hoof-like covering.

These are amongst my absolute favourite dinosaur fossil. The "arrowhead" shape is very distinctive and so exotic-looking when you find these in the rugged badlands. Often these are quite fragmented and incomplete due to their porous nature (especially in the distal end), which is why this piece is so special. The specimen retains a broad, tapered outline and a curved profile, with a thicker base narrowing toward the front. These features show the distinctive form of a hadrosaur’s terminal toe bone.

Weathering has worn portions of the surface and margins, exposing the porous internal bone in places. Visible cracks, shallow grooves and an uneven front edge document its preservation. Despite this wear, the overall shape remains readily apparent.

From the Harvey Negrich Collection, this specimen offers an accessible example of hadrosaur foot anatomy, with enough surface and structural detail for close examination.
