文摘
Several fossils from the Late Carboniferous of Montceau-les-Mines, France, are referred to a new taxon of fossil hagfish. Two specimens display impressions of two pairs of tooth rows that are strikingly similar in shape and organization to the horny teeth of modern hagfish. In addition, by its slender body shape, this new taxon is more suggestive of modern hagfish than the only previously known fossil form from the Carboniferous of the USA. Living hagfish being exclusively marine, this discovery raises the question of the reputedly freshwater environment of the Montceau-les-Mines ‘Konservat-Lagerstätte’.
