This Late Jurassic allosauroid from North America was a common predator that likely hunted in packs or ambushed armored prey like Stegosaurus with its powerful jaws and serrated teeth.

What is Allosaurus?

400

This massive therizinosaur from Late Cretaceous Asia, once known only from huge arms, had a pot belly for digesting plants plus claws for grabbing fish or insects, making it a true plant-and-meat eater.

What is Deinocheirus?

400

This Chinese sauropod from the Late Jurassic had the longest neck of any known dinosaur, with up to 19 elongated cervical vertebrae stretching over 30 feet.

What is Mamenchisaurus?

400

This Middle Jurassic sauropod from Niger had a relatively primitive build for its time, with a more horizontal neck posture and evidence suggesting it was an early form that bridged basal and advanced sauropods, discovered in the Tiourarén Formation.

What is Jobaria?

500

This rebbachisaurid sauropod from the Early Cretaceous of what is now Niger had over 500 tiny teeth arranged in "batteries" at the front of its broad muzzle, earning it the nickname "Mesozoic lawnmower" for grazing low-lying ferns and soft plants with its head held close to the ground.

What is Therizinosaurus?

This titanosaur from Late Cretaceous Argentina is currently considered one of the largest known land animals ever, with estimates of over 120 feet long and weighing up to 100 tons, based on massive limb bones and vertebrae found in Patagonia.

What is Patagotitan?

500

This Late Jurassic dwarf brachiosaurid from Germany, an example of insular dwarfism on ancient European islands, reached only about 6 meters long as an adult despite being a macronarian sauropod, with bone histology confirming slowed growth rates due to limited resources.
