This monster must have lived like a crocodile, cruising the murky waters of the coal swamps, lying in wait among the spreading roots of the giant club moss trees and in the reed beds of the great horsetails, waiting for unsuspecting prey to swim by.
Features:The body is tong and sinuous and the tail muscular and flattened from side to side. This must have been the main organ of propulsion, assisted by the ciorsal fin along the tail. It is one of the largest-known inhabitants of the coal swamps. It is completely covered by scales, more like a reptile than any modern amphibian. This feature seems to be left over from the ancestral fish, and suggests that these ancient amphibians did not breathe partly through their skins as modern amphibians do.
