This is another size comparison video from Global Data (a follow-up to their previously posted video), comparing the actual size of different types of animals, both extinct and extant. Mother Nature sure doesn’t make them like she used to, does she? She used to make them BIG. Now she makes them much smaller. That’s a shame. I’ve still got a brontosaurus sized pen15 though, just for the record. It can reach even the tallest trees, no problemo.
