Stromerichthys ("Stromer's fish") is an extinct genus of potentially chimaeric freshwater bony fish that lived during the Late Cretaceousepoch. It contains a single species, S. aethiopicus, described from a now-lost specimen with bones & scales from Egypt.[1][2]
In 2015, Cavin et al found Stromerichthys to most likely be a chimera (a fossil taxon erected on a mixture of different taxa), with the skeletal remains of the type specimen likely belonging to the giant bichirBawitius & a mawsoniidcoelacanth, while the scales found with the type specimen and throughout Europe & Africa belonged to the extinct gar relative Obaichthys. The destruction of the type specimen means that Bawitius or Obaichthys cannot be considered junior synonyms of Stromerichthys, and it is thus likely an invalid genus.[4]
