Description: | Specimen of a fossil fish, Sagenodus inaequalis, collected from the Coal Measures Group rocks rocks of Late Carboniferous, Westphalian, Langsettian - Duckmantian age from Cramlington Colliery, Cramlington, Northumberland (NE England). Toothplate with pterygoid bone.
This fossil tooth and bone is part of the upper jaw of an early lung-fish that was eel-like and grew up to 30 cm in length. Lungfish are the first vertebrates adapted to breath air. They lived in shallow salt and fresh water that was liable to become stagnant and dry up. Their teeth form a palate that is used to crush the shells and crustaceans that they fed on.
The specimen was found in Northumberland.
