20 Prehistoric Sharks - Size Comparison - Helicoprion and Edestus

20 extinct sharks size comparison: Eugeneodontida are an extinct order of extinct cartilaginous fish, an early form of shark similar to modern chimeras. Helicoprion had unique spiral tooth-whorls as a jaw, hence the name "spiral saw". Edestus had a single row of teeth on the top and bottom of its jaws and could bite then move its bottom jaw in a horizontal motion to saw and pull its prey into its mouth. Edestus is a Greek name derived from the word edeste, to devour, and is often called the "Scissor tooth" Shark. There are many unique sharks in the Family Helicoprionidae, Edestidae, and Caseodontoidea. Eugeneodont means "true origin teeth". I love the names. Many of these were the size of a great white shark, some even larger. Because cartilage doesn't fossilize well, remains are usually comprised of only teeth and sometimes parts of the jaw or skull. The body is a conceptual guess based on the type of teeth it had which corresponds to what it would eat, and what type of body would be required to hunt its selected type of prey. Also, from other remains from the time, as well as some modern ancestors, a range of traits can be guessed. I tried to include some variation of possible looks. These sharks are highly underrated, real life sea monsters of their time.
