Hadrosaur Dentary with Preserved Teeth, Alberta (disposition #001590)

A partial hadrosaur dentary (lower jaw bone) with preserved teeth, measuring 13 × 14 × 8 cm. The exposed dental material offers a detailed view of the tightly packed tooth arrangement characteristic of duck-billed dinosaurs.

Hadrosaurs possessed specialised dental batteries, with successive replacement teeth maintaining a working surface as older teeth wore down. The upper and lower tooth batteries worked together to process plant material.

This specimen preserves closely spaced tooth positions with teeth and tooth fragments remaining in place. Broken sections of the surrounding jaw expose portions of the dental battery, while the reverse retains a broad area of outer bone surface. Visible fractures, flaking and missing sections reflect its incomplete preservation.

From the Harvey Negrich Collection, the combination of jaw bone and retained teeth makes this an engaging specimen for examining the structure of a hadrosaur’s feeding apparatus.
