It is known from the Cretaceous of Egypt, parts of Eurasia, and the United States.[1] Its name stands for "false raven", due to the similarity of its teeth to those of Squalicorax ("raven shark"). While originally considered to (along with its relative Galeocorax) be a member of the family Anacoracidae (the family that Squalicorax belongs to), a study in 2012 moved it and Galeocorax into the new family Pseudocoracidae, making it only distantly related to Squalicorax.[2] References1. ^{{Cite web|url=http://fossilworks.org/?a=taxonInfo&taxon_no=34630|title=Fossilworks: Pseudocorax|website=fossilworks.org|access-date=2016-04-03}} {{Taxonbar|from=Q25095398}}{{paleo-shark-stub}}2. ^{{Cite journal|last=Cappetta|first=Henri|date=Dec 1, 2014|title=New Squalicorax species (Neoselachii: Lamniformes) from the Lower.
