Concavotectum

Concavotectum is an extinct genus of tselfatiiforme bony fish that lived during the Cenomanian in Morocco and possibly Egypt.[1][2] It was discovered and named in 2008 and is known from a single well preserved hand-sized skull and a few isolated vertebrae discovered in the Kem Kem Group (Gara Sbaa Formation).[3][1][4] The type species, C. moroccensis, was named in 2008[4] and described in 2010.[1] A possible second and third specimen, found in the Baharija Formation, consists of a 2 skulls and several vertebra, which were all destroyed on the night of 24-25 April 1940, during the Bombing of Munich in World War II. They are currently the holotype of the possible synonym Paranogmius.[5]
