Small Theropod Phalanx (Dinosaur Digit Bone), Alberta (disposition #001590)

Theropods are a group of mostly carnivorous dinosaurs, although some did evolve into ominvores, insectivores and even herbivores. Often their bones are light-weight, hollow and bird-like. This is a small theropod phalanx, or digit bone, from Alberta, measuring 4.75 × 2.5 × 2.5 cm. Phalanges formed the articulated fingers and toes of dinosaurs. This specimen’s exact position within the hand or foot, along with its genus and species, remains undetermined.

The bone retains a narrowed shaft between expanded ends, with a rounded joint contour and a distinct depression on the side. These features preserve the recognizable form of an articulated digit bone and illustrate how neighbouring elements fitted together.

From the Harvey Negrich Collection, this fossil offers a compact example of theropod skeletal anatomy. Its defined joint contours and exposed bone structure make it an engaging addition to a dinosaur collection or comparative anatomy display.
