Anacoracidae
The Anacoracidae are an extinct shark family in the order Lamniformes. They lived throughout the prehistoric oceans during the Cretaceous period. The most numerous and well-known member of this family is "Squalicorax", which was one of the most common marine predators during the period. Formerly, other shark genera such as "Pseudocorax" and "Galeocorax" were considered to belong to this family, on the basis of their similar teeth; however, a 2012 revision by Henri Cappetta moved these sharks into their own family, the Pseudocoracidae.
