Debeeriidae (alternatively spelled Debeeridae) is a family of holocephalan fishes from the Mississippian subperiod of the Carboniferous. It is the only family of the order Debeeriiformes.[1] It is named after the type genus, Debeerius, which itself is named in honor of Gavin de Beer. Members of this family and order possess a large spine on the dorsal fin, an opercular cover over the gills,[2] and an autodiastylic (two-jointed) jaw suspension.[3] Both genera in the family are known from exceptionally well-preserved specimens found in the Bear Gulch Limestone member of the Heath Formation.[2][3]
