Enchoteuthis melanae Coelophysis approximately 30 to 25 millionEnchoteuthis melanae was a coleoid cephalopod from the Late Cretaceous of North America, known from fossil remains recovered from marine deposits of the former Western Interior Seaway. Traditionally, related material was often associated with Tusoteuthis longa, but later revisions of large Cretaceous gladii have indicated that part of this material belongs to Enchoteuthis melanae, a taxon within Enchoteuthididae. This group represents one of the most
