Elasmosaurids probably ate small fish and marine invertebrates, seizing them with their long teeth, and may have used gastroliths (stomach stones) to help digest their food. Elasmosaurus is known from the Pierre Shale formation, which represents marine deposits from the Western Interior Seaway.

Are Elasmosaurus carnivores?
It was a carnivorous hunter which used its long neck to get close to prey without them noticing. A swift flick of the neck could catch them unawares. Its small head limited the size of what it could eat. Elasmosaurus spent all its time in the water, often cruising coastal waters for shoals of fish.
Is an Elasmosaurus a dinosaur?
Elasmosaurus was a plesiosaur, a type of marine reptile. It was not a dinosaur, though it coexisted with many dinosaurs. The first Elasmosaurus fossil was discovered in 1868.
What killed the Elasmosaurus?
It died out with the dinosaurs and other prehistoric marine reptiles at the end of the Cretaceous.
Is the Elasmosaurus extinct?
Elasmosaurus is an extinct genus of plesiosaur with an extremely long neck that lived in the Late Cretaceous.
How did Elasmosaurus eat?
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.
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.
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.
How fast can the Elasmosaurus swim?
“Studies have shown an optimal swimming speed for plesiosaurs of about 0.4 m/s (1.44 km/h) to a maximum sustained speed of about 2.5 m/s (9 km/h) (like today's dolphins), depending on joint movement of the limbs and specific species.
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.
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.
How many bones does a Elasmosaurus have?
Elasmosaurus represents this group here at the park. Its distinctive neck contains 72 bones—ten times more than any mammal.
What dinosaurs had 500 teeth?
This bizarre, long-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with more than 500 replaceable teeth. The original fossil skull of Nigersaurus is one of the first dinosaur skulls to be digitally reconstructed from CT scans.
How many teeth did the Elasmosaurus have?
Elasmosaurus can be distinguished by its six premaxillary teeth and 71 cervical vertebrae.
