How Dinosaurs Got So Big

How Dinosaurs Got So Big

Dinosaur of the day Uberabatitan, A giant titanosaur that may have had the largest teeth of any known sauropod.

In dinosaur news this week:

  • Sauropods grew to be the largest land animals of all time with many special adaptations that helped them reach "super giant" sizes
  • Bruhathkayosaurus may have been the heaviest land animal of all time with weight estimates from 80–190 tonnes
  • Sauroposeidon may be the tallest sauropod (and land animal) of all time—with Giraffatitan proportions bringing it to about 17m (56ft) tall
  • Sauropod babies were already built to grow large
  • It's not just sauropods that had special adaptations to grow so large—Theropods had them too
  • Early sauropod ancestors evolved very rapid growth before they evolved gigantic sizes
  • A new study found 36 unique times that sauropods evolved gigantism
  • A hadrosaur long thought to be an island dwarf turned out to just be young and was still growing
