Concavotectum

Concavotectum is an extinct genus of freshwater plethodid ray-finned 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).^[1][3][4] The type species, C. moroccensis, was named in 2008^[3] 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 discovered in 1916 and were all destroyed on the night of 24-25 April 1944, during the Bombing of Munich in World War II. They are currently the holotype of the possible synonym Paranogmius.^[5] Some differences are evident between the surviving illustrations of Paranogmius and the skull of Concavotectum, so they are tentatively considered distinct genera, and a new genus is still necessary given the destruction of the former type specimens.^[3]
