Anthracosuchus

Anthracosuchus (meaning "coal crocodile" in Greek) is an extinct genus of dyrosaurid crocodyliform from the Paleocene of Colombia. Remains of Anthracosuchus balrogus, the only known species, come from the Cerrejón Formation in the Cerrejón mine, and include four fossil specimens with partial skulls. "Anthracosuchus" differs from other dyrosaurids in having an extremely short (brevirostrine) snout, widely spaced eye sockets with bony protuberances around them, and osteoderms that are smooth and thick. It is one of the most basal dyrosaurids along with "Chenanisuchus" and "Cerrejonisuchus". The species name is a reference to the Balrog, a creature in J. R. R. Tolkien's fantasy novel "The Lord of the Rings" that could, like the remains of "Anthracosuchus", be found in a mine.
