25 Myths About Dinosaurs You Might Need To Stop Believing

Posted by , Updated on December 22, 2015


Dinosaurs are some of our favorite creatures to have ever ruled the Earth. Hulking beasts at the top of the food chain whose carnivorous tastes led them to eat whatever was in sight, right? Well, all three of the statements in the last sentence are not completely true. Dinosaurs were an incredibly diverse species that spanned many millions of years – far far longer than we’ve been on Earth. The most popular dinosaur movie so far – Jurassic Park – may be entertaining, but most of what it presents on dinos is inaccurate. (Even the name is wrong – its dinosaurs didn’t even live in Jurassic times!) Calling out falsehoods from Hollywood magic to outdated textbooks myths, this list is full of the facts when it comes to dinosaurs, not the commonly held myths and misconceptions regarding the massive creatures. Have you heard that dinosaurs were slow and stupid? (They weren’t.) What about that dinosaurs were all wiped out by an asteroid impact? (Not entirely true.) Whether you’re an amateur paleontologist or just grew up watching “The Flintstones”, there’s sure to be a dinosaur myth on this list you haven’t heard of yet. Read on to find out if you believe any of these 25 myths about dinosaurs you might need to stop believing.

A recently dug-up Cryolophosaurus fossil in the South Pole is proving that dinosaurs lived and thrived even in freezing polar regions. Near to this fossil, paleontologists found numerous other partial dinosaur skeletons.


Dinosaurs had hind-brains

Paleontologist Charles Marsh found a wide cavity in the hip-area of various dinosaurs’ spinal canals which he speculated as the location of a rear, second brain. This dinosaur assumption has since been disproven; many vertebrates, including us humans, have an enlarged nerve cluster at the base of our spines.


All prehistoric reptiles were dinosaurs

Though many people think “dinosaur” is the name for any reptile which walked the Earth before the appearance of humans, only about 10% of reptiles in the Mesozoic Era were actually dinosaurs.


Dinosaurs were terrors for mammals

While dinosaurs did pose a significant threat to mammals, mammals also posed a major threat to dinosaurs. Just as in today’s food chain, larger mammalian carnivores feasted on smaller (dino) meat.


The Flintstones is dino-truth

The first dinosaur to appear in “The Flintstones” opening sequence was long identified as a Brontosaurus. But this is a dinosaur myth! There was never a dinosaur like the Brontosaurus. Paleontologists incorrectly put the head of a Camarasaurus on the body of an Apatosaurus.
