A Large, Freshwater Chanid Fish (Ostariophysi: Gonorynchiformes) from the Upper Cretaceous of Madagascar
Isolated fossil bones from freshwater Upper Cretaceous (Maastrichtian) deposits in the Mahajanga Basin of northwestern Madagascar are identified as belonging to a gonorynchiform fish. Multiple elements representing the same bone, including opercles, hyomandibulae, frontals, and basioccipitals, indic...
