Johnlongia
Extinct genus of shark
From Wikipedia, the free encyclopedia
Johnlongia is an extinct genus of sand shark from the Cretaceous period. It contains two described species, J. parvidens and J. allocotodon, and possibly a third unnamed species from the Niobrara Chalk.[1] It is presumed piscivorous; however, it forms a clade with an early filter-feeding shark genus, Pseudomegachasma.[2]
