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!

    Large Dinosaurs May Have Had Air Sacs Inside Their Bodies That Decreased Their Overall Weight

    From Redditor u/MrJoestar42069:

    TIL the reason some dinosaurs were able to get so large was that they had "air sacs" in and around their bones, which prevented them from being crushed under their own weight and allowed them to grow to enormous sizes.

    'Dreadnoughtus,' One Of The Largest Dinosaurs To Ever Exist, Weighed Nearly 60 Metric Tons

    From Redditor u/0h_myg0ssh:

    TIL of Dreadnoughtus, one of the largest dinosaurs that ever existed. The fossil skeleton of the individual was 85 feet, but was not even a fully grown adult - and it was expected to grow even larger!


    [Editor's Note: Sixty metric tons is equivalent to 132,277 pounds. What's really exciting is that scientists discovered about 70% of Dreadnoughtus schrani's "key" skeleton, providing much more physical evidence of this dinosaur than others of its size.]
