Spinosaurus's long snout, its non-serrated, interlocking teeth, and the oxygen isotopes found in its fossils suggest that this was one of the few piscivorous (fish eating) dinosaurs. Although it probably did scavenge on larger dinosaurs when the opportunity arose, and it probably occasionally hunted smaller dinosaurs, Spinosaurus lacked the jaw and tooth strength necessary to hunt a dinosaur nearly as large as itself, and especially one that was larger.
yes spinosaurus and giganotosaurus were bigger than t rex and so was the brachiosaurus and many other dinosaurs.
Spinosaurus
spinosaurus
Spinosaurus, as of now, is the largest meat-eating animal to walk the earth. Therefore, it would be assumed that Spinosaurus was large enough to hunt smaller dinosaurs, if none were bigger than it. The only time another dinosaur might try to kill a Spinosaur is if it was wounded, ill, or very young. Even an older Spinosaur might still be able to defend itself due to sheer size and mass.
One of them was spinosaurus.
The spinosaurus.
dinosaurs eat smaller dinosaurs because they know if they pick on bigger dinosaurs they are putting themselves at risk. however if they eat smaller dinosaurs that cannot fight back as well as lets say the stegosaurus the carnivores will have a free meal. this is also called survival instincts.
spinosaurus because it's bigger
Pretty much all dinosaurs lay eggs, so Spinosaurus likely did too.
Birds are the closest living relatives of spinosaurus and all past dinosaurs.

The smallest carnivorous dinosaurs, such as Compsagnathus, are insects and small vertebrates. Large carnivorous dinosaurs usually ate large and small herbivorous dinosaurs. Some, however, ate fish, including Spinosaurus and Baryonyx.
