Eugeneodontida is an extinct and poorly known order of bizarre cartilaginous fishes. They possessed a unique "tooth-whorl" on the symphysis of the lower jaw as well as pectoral fins supported by long radials. The palatoquadrate was either fused to the skull or reduced. Now determined to be within Holocephali, their closest living relatives are ratfish. The meaning of the name Eugeneodont correlates to "true origin teeth", and comes from the Greek words eu (good/true), geneos(race, kind, origin) and odon (tooth.)
Members of Eugeneodontida are further classified into different families, the most well-preserved members that have been discovered are commonly placed within the families Helicoprionidae ("Spiral Saws"), and Edestidae ("Those which Devour"), the former containing the genera Helicoprion, Sarcoprion and Parahelicoprion, and the latter containing the genera Edestus, Listracanthus and Metaxyacanthus. All eugeneodonts are thought to be obligate carnivores, with each genera having specialized feeding behaviors, territory ranges and specific prey.

Helicoprion was an ancient fish that lived many millions of years ago before the dinosaurs. For over one hundred years the only evidence of these prehistoric sea creatures were their very strange spiral teeth. This video will explain the difficulty that can be had in paleontology sometimes and how this fish was constructed in the end.

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.

Hunting Down an Ancient 'Buzzsaw Killer': The Helicoprion
After examining 3-D printed models of fossil specimens, Jeremy Wade gets a look at an ancient 'Buzzsaw Killer'.

This is by far one of my favorite groups of wacky, weird prehistoric fish called…
Eugeneodontida, a very peculiar set of cartilaginous fish that were not sharks, but closely related to chimaeras, and lived for over 160 million years from the Devonian to the Early Triassic.
Their most defining and peculiar feature is their spiral-shaped tooth whorls, which are by far some of the strangest sets of teeth ever on the animal kingdom, which they used to capture slippery prey such as squid, that were then crushed by their powerful jaws before being swallowed whole.
Making the members of Eugeneodontida look like they have alien jaws.
They also had a very weird jaw structure known as an autodiastylic jaw, with several separate pieces that could move independently of each other, allowing them to open their mouths wider and catch larger prey.
Even more, they were also pretty huge fish, with species like Parahelicoprion growing up to 39 feet, or 12 meters long.
That is why I have dubbed the Eugeneodontida the “Whorltooth Titans”, and I love them!

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.

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.
