#1. Henodus Chelyops
(“Turtle-Faced Single Tooth”) Late Triassic Period (200 Million years ago)
What did the Henodus look like?
Kinda like that turtle you ran over with your car. Although scientifically it kind of looks like the estranged love child of a manta ray and a turtle, The Henodus doesn’t actually trace its lineage to either one.
How big was the Henodus?
It measured 1 meter in length.
What the hell was it?
Part of the ancient group of marine reptiles called Placodont’s. The Henodus is distinguishable by single tooth on each side of its mouth that was probably used for opening tasty shellfish like a cheap nutcracker.
Henodus remains have been found in non marine deposits, so it may have lived in freshwater lagoons, and likely enjoyed an amphibious nature that allowed it to lay its eggs on land, proving once and for all that the egg actually did come before the chicken.
What did the Dakosaurus look like?
When the first Dakosuarus skull was unearthed in Patagonia, Argentina, the scientists quickly named it “Godzilla” due to its dinosaur type snout, and lizard like appearance. Its body was streamlined for hydrodynamic efficiency with paddles instead of feet and a finned tail.
What the Hell was a Dakosaurus anyway?
The Dakosaurus was neither a Dinosaur nor a Fish, but actually a prehistoric crocodile belonging to an extinct genus within the family Metriorhynchidae. They lived during the Late Jurassic and Early Cretaceous period
The name Dakosaurus actually means “Tearing Lizard”, and is derived from the Greek Dakos- (“to tear”) and -sauros (“lizard”).
How big was the Dakosuarus?
All currently known species would have been approximately four to five meters in length making them larger than our modern crocodiles. Try and picture a great white shark with a dinosaur head, and you’ll get the idea.
What did the Kronosuarus look like?
Kind of like a cross between a Playpus and a Dinosaur, the Kronosaurus was the biggest and baddest marine predator in the western queensland of Austrailia. It has appropriately taken its name from the greek deity Kronos.
What they hell was it?
It came from an extinct genus of short-necked pliosaur, and once one of the largest of the group, hence the reference to Kronos
Just How Big Was This Thing?
It had a head the size of the average human, teeth the size of a bananas, and an approximate length of 9–10 meters (30–33 feet).
“Uhhh, is that a Banana in your mouth or are you just happy to eat me?”
What did a Tylosaurus look like?
The Tylosaurus resembled a cross between a monitor lizard and a serpent. A distinguishing characteristic of Tylosaurus is its elongated, cylindrical nose which may have been used to ram and stun prey or possibly even used for combat between its own species. (Tylosaurs were known to eat each other)
How big was this thing?
It measured about 50 feet (15 meters)
Just What the hell was a Tylosaurus?
Deriving its name from the Greek word “tylos” (protuberance, knob) and the word “sauros” (lizard) the Tylosaur was a mosasaur, (a large, predatory marine lizard closely related to modern monitor lizards and to snakes.) Of course its eating habits were probably closer to quoll or tasmanian devil of the ocean since the Tylosaurus had a varied diet that included fish, sharks, smaller mosasaurs, plesiosaurs, flightless diving birds, and pretty much anything it could torpedo down its gullet.
What did an Archelon look like?
The Archelon kind of looked like its closest living relative, the leather back turtle. It didn’t carry with it solid shell, but instead used a skeletal framework that supported a leathery or bony carapace. The Archelon can be distinguished by a pointed tail, a narrow skull, a high-vaulted shell, and a pronounced overbite.
How big was it?
Archelon (Greek meaning ruler turtle) is a genus of extinct sea turtle, the largest that has ever been documented. The live weight of an Archelon ischyros is estimated at more than 2000 kg (4500 lbs).
As big as it was however, this turtle couldn’t retract its head or flippers making it vulnerable to attacks from other predators.
What did a Temnodontosaurus look like?
It sort of looked like flipper with an elongated snout jam packed with pointy teeth.
What the hell was a Temnodontosaurus?
The Temnodontosaurus was an ichthyosaur from the Early Jurassic, some 198 and 185 million years ago (Hettangian – Toarcian), in Europe (England & Germany). It is the only genus in the family temnodontosauridae
How big was this thing?
The Temnodontosaurus or “cutting tooth lizard” was larger than a double decker bus. Its dolphin like body exceeded 12 meters (40 ft) in length, while the eyes of the Temnodontosaurus were the size of dinner plates. Their eyes measured approximately 20 cm (8 in) in diameter making them some of the largest eyes of any known vertebrate.
All the better to see you with
What does it look like?
It looked like its distant cousin we know as a salmon, just add a set of Sabre Teeth. Its skull had an appearance somewhat reminiscent of modern deep-sea fishes, such as the anglerfish and viperfish.
What the hell was it?
Enchodus were part of an extinct genus of bony fish with large fangs.
How big were the Enchodus?
Well, their fangs measured 6+ cm in length. Their the total body length was only about 1.5 meters, but we suspect they would give an modern fisherman a good run for their money.
