People can disagree on almost any topic - which form of music is the best, whose brand of politics is correct, even how to boil water - but most of us can agree on one, solid fact: dinosaurs are cool. In its 4.5 billion-year lifetime, the planet's most objectively metal era was the Mesozoic Era, the 179-million-year period when dinosaurs ruled the Earth.

Reddit users most definitely agree, and they've shared several cool dinosaur facts over the years - many of which may surprise you. Did you know pterodactyls weren't dinosaurs, that dino remains have been found trapped in amber, or that you can keep any fossils you find in your own backyard (if you live in the USA)? There's plenty more interesting facts about dinosaurs below, so vote up the ones you never knew before!
