Complete Dinosaur Names List: 150+ Dinosaurs and How to Say Them

Let's talk about what these animals were actually like — because the creatures behind these names are way more interesting than the names themselves.

Therizinosaurus had claws up to a meter long. That is longer than your entire arm. Scientists think it used those ridiculous claws to pull branches down and eat leaves — not to hunt. A giant plant-eater with horror-movie claws.

Carcharodontosaurus was a meat-eater from North Africa that rivaled T. rex in size. Its name means shark-toothed lizard, and those serrated teeth could slice through bone. It shared its world with Spinosaurus, which means North Africa during the Cretaceous was genuinely terrifying.

Eoraptor is one of the oldest dinosaurs ever found — it lived about 231 million years ago, right near the dawn of the dinosaur age. It was only about the size of a dog. Hard to believe that tiny creature was a distant ancestor of creatures like Argentinosaurus, the largest land animal that may have ever existed.

This dinosaur names list is packed with record-holders you might not expect.

Argentinosaurus is probably the heaviest dinosaur ever discovered — estimates put it at 70 to 80 metric tons. That is heavier than a dozen elephants stacked together. Found in Argentina, it was a long-necked sauropod that likely spent most of its life just eating enough to fuel that enormous body.

Compsognathus sits at the opposite extreme. It was one of the smallest non-avian dinosaurs ever found — about the size of a turkey, with a long tail and a tiny skull. For a long time it held the record for smallest known dinosaur.

Parasaurolophus had one of the most bizarre skulls in the whole dinosaur world. That hollow crest on its head was basically a built-in musical instrument — paleontologists think it could produce deep, resonant calls to communicate across forests. A hadrosaur with its own built-in trombone.

Ankylosaurus had a tail club made of fused bone that could shatter the leg of a T. rex. It was basically a living tank — armored on top, weaponized at the back.
