Hadrodus priscus
Hadrodus priscus is a species of pycnodont, similar to anomoeodus. It also contained small circular teeth in its jaw and had a crushing dentition, suggesting that it fed on mollusks and crustaceans. Its remains are quite rare to someone not searching for micro fossils as even its larger teeth are quite small. The most abundant find for this species of fish is its pharyngeal (gill) teeth, which are extremely unique and easily recognizable. These teeth were thought to have been used in some way to help process its food after crushing it up.
Size: 2-5mm
Age: Late Cretaceous
Pharyngeal teeth
The pharyngeal teeth are not a too uncommon site when looking through bulk micro matrix. They are always some mix of yellow towards the crown, brown towards the root, and slightly transparent. They are typically hooked, and often missing a majority of the root.
