Gymnotrachelus
Genus of fishes (fossil) / From Wikipedia, the free encyclopedia
Gymnotrachelus is an extinct monospecific genus of large selenosteid arthrodire placoderm of the Late Devonian known from the Late Famennian Cleveland Shale of Ohio.[1] The type species Gymnotrachelus hydei was originally reconstructed as physically resembling Selenosteus, with slightly smaller orbits (i.e., having a broad, box-like head). Later specimens led to a reappraisal, and now G. hydei is thought to have a more gar-like or barracuda-like build.[2]
