Cool dinosaur facts for kids

One of the neat things about dinosaurs is that we are constantly learning new information about them. When new fossils are discovered, they change what we believe about dinosaur superlatives like largest dinosaur, oldest known dinosaur, etc.

The facts about dinosaurs below are based on current fossil information, but if you see something that doesn’t appear correct, please click here to contact us and we will update it!

The oldest known dinosaur is the Nyasasaurus Parringtoni. It was discovered in a 243 million year old fossil found in Tanzania, Africa.

While we think of dinosaurs as enormous creatures, they actually had a wide range of sizes. One of the smallest known dinosaurs is the Compsognathus, which is roughly the size of a chicken.

The Argentinosaurus is believed to be the largest dinosaur. Though no complete Argentinosaurus skeletons have been found, estimations put the dinosaur’s height between 37 to 40 meters (121 to 131 feet), and weight between 90 to 100 metric tons (99 to 110 tons).

To put the massive size of the Argentinosaurus in perspective, a single vertebra from this dinosaur is the same size as a fully grown human being. Talk about a big dino!

If you’re a big fan of dinosaurs and want something dinosaur-themed to display in your home, you can get your own dinosaur fossil replica.

  • You may be surprised to learn that not all dinosaurs lived at the same time. For example, the Stegosaurus was extinct for roughly 80 million years before the T-Rex appeared. This means that humans are closer in time (65 million years) to the T-Rex than the Stegosaurus was! 
  • Birds are descended from dinosaurs. More specifically, birds evolved from theropods (a category of two-legged, three-toed, dinosaurs that includes the T-Rex)
  • Some dinosaurs had feathers. Fossil evidence proves that, unlike their depiction in the Jurassic Park movies, Velociraptors had feathers!
  • Dinosaurs can be classified by their dietary preferences. There are carnivores, which ate primarily meat (eg. Tyrannosaurus Rex), herbivores which primarily ate plants (eg. Brachiosaurus), and omnivores which ate both plants and animals (eg. Citipati).
  • In 1677, Robert Plot discovered the first dinosaur bone. He originally believed it was a large human bone, but further analysis revealed it was the first dinosaur bone ever discovered.
