Archaeolamna is an extinct genus of mackerel shark from the Cretaceous period.[1] There are currently two named species, one of which has two named subspecies. Its isolated teeth have been found in Europe, North America, and Australia. A single associated dentition is known from the Pierre Shale of Kansas, USA.[2] The grasping-type dentition and large size of these teeth suggest a diet of mainly large fish and possibly sea reptiles. There is some evidence of scavenging upon Plesiosaurs in the Judith River Formation.[3]
