How did a spinosaurus get its food?

Answer 1

Spinosaurus primarily ate the fish that lived in local swamps. They would wade into a swamp and then possibly submerge their jaws in the water, because their jaws may have had pressure sensors for detecting fish that the Spinosaurus couldn't see. When a fish came within reach, they would strike, and then swallow the fish whole. On occasion, they probably hunted small herbivorous dinosaurs and scavenged on large dinosaurs.

Answer 2

It is unclear whether the Spinosaurus was a carnivore (meat-eater) or a piscivore (fish-eater). But so far evidence seems to show that it was a carnivore, still we are not 100% certain.

The Spinosaurus's long jaws, which are similar to crocodiles, would have allowed them to easily scoop prey from the water. A long snout would mean they could lay in the water and breathe through their nostrils, like a crocodile. However this was probably unlikely due to its huge size.

However, also like crocodiles, it would have also allowed them to snap and crunch land animals/other dinosaurs.

Answer 3

Spinosaurus's main prey was fish. It would have waded into the water and waited, possibly with its jaw submerged in the water to sense pressure changes that would indicate a fish's location. When it detected a fish, it would snatch it and then probably swallow it whole, unless the fish was huge, like a several meter Mawsonia, in which case it would kill it and then take it to shore where it could eat it in bite sized pieces.

Answer 4

Actually, it ate mainly fish. It walked in the water and waited for a fish to come by. Next, it saw a fish. Now, it could use that long snout to catch one.

Answer 5

The spinosaurus was a carnivore at the top of the food chain. It ate fish, large crocodiles, and was cannabalistic at times.
