Megafauna Size Comparison
“Human- a 6 foot (1.8m tall) man.
African Bush Elephant- 3 meters tall at shoulder. The largest of modern elephants.
Songhua River Mammoth- 5.3 meters at the shoulder! WAY larger than most other mammoth species (and a good many dinosaurs)!
Triceratops- 8-9 meters long, approx 8-9 feet tall, and quilled. Its skull is one of the largest of a land animal.
Tyrannosaurus Rex- 12 meters long, with a 5 foot skull. Unique late-cretaceous predator. Stockier and brawnier than other giant theropods.
Brachiosaurus- 13 meters high with its head raised. Although smaller than more recent sauropods, still by far one of the largest compared to most.
Hatzegopteryx- largest yet pterosaur- with a 3 meter skull and 12 meter wingspan! Also hairy. Spent most time foraging the ground- but could still fly!
Great White Shark- a larger specimen at 6 meters long. Usually they only reach 4m.
Orca (aka Killer Whale)- 7-8 meters long (average). Top predator of today’s oceans. Can take down larger animals than itself!
Temnodontosaurus- 9-12 meters: top predator of early Jurassic; a meaner form of Ichthyosaur. Also has some of the largest eyes in the animal kingdom.
Megalodon- estimated 12-16 meters long. Depicted at 12m. Each tooth is as large as a man’s hand! Lived through dinosaur AND mammal eras!
Mosasaurus beaugei- 15- 18 meters, with a near 2 meter skull; the largest of the mososaurs.
Leviathan Melville- AKA Moby Dick: estimated 15-18 meters; NEWLY discovered predatory whale. Has a 3 meter skull and teeth larger than bananas.
Predator X: 15 meters long; With a 3 meter skull. One of the largest pliosaurs and top predator of late jurassic/early cretaceous.
Leedsichthys: 9- 22 meter estimate: Depicted at 14 meters. Known only from collosal fin bones and thousands of fragments.
Shonisaurus sikkanniensis: 22-25 meters long. 5 meter skull with no teeth. Largest Ichthyosaur. Likely ate squid like modern sperm whales do.
Sperm Whale: 18-22 meters long. The largest toothed animal on the planet!
