Large Hadrosaur Toe Bone (Phalanx I), Alberta (disposition #001590)

A substantial hadrosaur phalanx (toe bone) from a duck-billed dinosaur, measuring 13 × 11 × 7.5 cm. This bone formed part of an articulated toe, with broad joint surfaces connecting it to neighbouring bones.

Hadrosaurs typically had three digits (toes), comprised of a variety of phalanges and uguals. This is one of three "phalanx I" digits in the foot and is the largest toe bone. Its size speaks to the amount of weight this robust bone had to support! Shockingly, even with their dense bone structure and giant size, these are quite uncommon to find (I have only collected a handful in 30 years). Note the colour change occurring diagonally across the bone; this indicates that it was partially exposed and had bleached to a lighter colour, while the buried portion was protected and retained its darker brown shade.

From the Harvey Negrich Collection, its substantial size and preserved joint contours make it an engaging display specimen for a collection focused on dinosaur anatomy.
