Styxosaurus, like most other plesiosaurs, probably fed on belemnites, fish (Gillicus, etc.) and squid. With its interlocking teeth, Styxosaurus could grab on to its slippery prey before swallowing it.

How long did Styxosaurus live?
The Styxosaurus was a Plesiosaurus that belonged to the Elasmosauridae family. It lived during the late Cretaceous period in the Campanian stage, about 85-70 million years ago.
Is a Styxosaurus real?
Styxosaurus was an elasmosaur, a long-necked variety of the marine reptiles called plesiosaurs. ... About half that length was neck, a feature that allowed Styxosaurus to sneak up on schools of fish as it slowly cruised the shallow waters of the Late Cretaceous seas.
Where does the Styxosaurus live?
The type specimen was found on Hell Creek in Logan County, Kansas and is the source of the genus name coined by Samuel Paul Welles, who described the genus, in 1943.
How big is a Elasmosaurus?
classification and characteristics. For example, Elasmosaurus, a plesiosaurid, had as many as 76 vertebrae in its neck alone and reached a length of about 13 metres (43 feet), fully half of which consisted of the head and neck.
Is Cretoxyrhina a mammal?
Cretoxyrhina (/krɪˌtɒksiˈrhaɪnə/; meaning 'Cretaceous sharp-nose') is an extinct genus of large mackerel shark that lived about 107 to 73 million years ago during the late Albian to late Campanian of the Late Cretaceous.
What killed the Elasmosaurus?
It died out with the dinosaurs and other prehistoric marine reptiles at the end of the Cretaceous.
Why did Elasmosaurus have a long neck?
Some researchers have also suggested that the long necks of elasmosaurs might have been used to generate lift in a similar way. Their long necks have a slight bend around the middle of their length which could be used like the curved wing of a plane. This would further help with long-distance cruising.
What did Elasmosaurus do?
It ate small bony fish, amonites (molluscs) and belemnites (similar to squid). It also ate small stones to help it digest its food, in the same way that crocodiles, seals and sea lions do today.
What did Cretoxyrhina look like?
Cretoxyrhina's were smooth, curved, and grew more than two inches (five centimeters) long. Bite marks and teeth embedded in the bones of its prey suggest Cretoxyrhina chomped with brutal force.
How big is a Helicoprion?
Based on the proportional size of caseodontoid tooth whorls, this may indicate that Helicoprion individuals could reach 5 to 8 meters (16.4 to 26.2 feet) in length, rivaling the size of modern basking sharks.
What is the biggest shark in history?
The biggest shark in the world
O. megalodon was not only the biggest shark in the world, but one of the largest fish ever to exist. Estimates suggest it grew to between 15 and 18 metres in length, three times longer than the largest recorded great white shark.
Is the Elasmosaurus alive?
Elasmosaurus (/ɪˌlæzməˈsɔːrəs, -moʊ-/;) is a genus of plesiosaur that lived in North America during the Campanian stage of the Late Cretaceous period, about 80.5 million years ago.
What's the spitting dinosaur in Jurassic Park?
The poison-spitting dinosaur reconstructed in Jurassic Park is Dilophosaurus. At the time the movie was produced, there was no evidence that this or any other dinosaur spat poison or had poisonous saliva of any kind.
Did Elasmosaurus breathe underwater?
Like Other Marine Reptiles, Elasmosaurus Had to Breathe Air
They weren't equipped with gills, like fish and sharks, and couldn't live below water 24 hours a day.
How many dinosaurs lived underwater?
Question #14: Were there any swimming dinosaurs? Answer: No dinosaurs were adapted to an entirely aquatic life, although some may have gone into the water to get prey. Baryonyx, for example, was found with fossilized fish scales in its stomach.
Did the Elasmosaurus have predators?
Elasmosaurs preyed primarily on fish and prehistoric cephalopods (a class that includes present-day squids and octopuses) such as belemnites and ammonites. Scientists believe that elasmosaurs were relatively slow-moving ambush predators that used their long necks and thin, pointed teeth to catch their prey.
