Moscovian life

Anthracosaurus is an extinct genus of embolomere that lived during the Late Carboniferous (around 315 million years ago) in what is now Scotland, England, and Ohio. Measuring around long, it was a large, aquatic eel-like predator. It has a robust skull about in length with large teeth in the jaws and on the roof of the mouth. Anthracosaurus probably inhabited swamps, rivers and lakes. Its name is Greek for "coal lizard".

Ornithoprion is an extinct genus of cartilaginous fish. The only species, O. hertwigi, lived during the Moscovian stage of the Pennsylvanian subperiod, which spanned from . Its fossils are preserved in black shales from what is now the Midwestern United States. The study of Ornithoprion was performed primarily via x-ray imaging, and at the time of its discovery it represented one of the best known holocephalans of the Paleozoic era. The classification of the genus has been the subject of debate due to its unique anatomy, and it is now placed in the order Eugeneodontiformes and the family Caseo
