The type II sail-finned sea serpent or marine Dimetrodon is a Champagne type of sea serpent, based on worldwide sightings as recent as 1999, including the Valhalla (1905) sighting. It is 12–84 ft (3–25 m) long, and is distinguished by a prominent fan-like dorsal fin, a turtle-like head with toothless jaws, and an unusual "sculling" ostraciform locomotion. Using a classification index, it scores with the plesiosaurs between modern reptiles and primitive mammals, leading Bruce A. Champagne to suggest it may be a transitional form.[1]Cameron McCormick compares it to the super-eel of the Heuvelmans system.[2]
