Herbivores
This famous plated dinosaur from the Jurassic Period is known for its distinctive back plates and spiked tail.
What is Stegosaurus?
This iconic Late Cretaceous predator from North America, often called the "king of the dinosaurs," had tiny arms and a bite force strong enough to crush bone.
What is Tyrannosaurus rex?
This bird-like theropod from Late Cretaceous Asia was once thought to be an "egg thief" due to fossils found atop nests, but is now known as an omnivore that likely ate plants, small animals, and possibly eggs.
What is Oviraptor?
This Jurassic sauropod, famous for its incredibly long neck and front legs longer than its hind legs, is often depicted reaching high into the treetops like a giraffe.
What is Brachiosaurus?
This Early Cretaceous titanosaur from India had unusually wide hips and a distinctive "Indian" name, with fossils showing evidence of armor-like osteoderms in some relatives, though debated for this genus itself.
What is Isisaurus?
This long-necked sauropod from the Jurassic, often confused with Brontosaurus in old movies, used its whip-like tail for defense while munching on high plants.
what it diplodocus
This feathered pack-hunting dromaeosaur from Late Cretaceous Mongolia inspired the "raptors" in Jurassic Park, though the real ones were turkey-sized with a deadly sickle claw.
What is Velociraptor?
This small, agile theropod from Late Jurassic Europe, about the size of a chicken, had sharp teeth and is thought to have eaten insects, small lizards, and possibly plants or carrion.
What is Compsognathus?
This stocky Jurassic sauropod from the Morrison Formation had a relatively short neck for a sauropod, boxy skull, and spoon-shaped teeth ideal for stripping leaves, making it one of the most complete and well-studied long-necks.
What is Camarasaurus?
This Late Cretaceous North American titanosaur, one of the last sauropods before the end-Cretaceous extinction, was found in the American Southwest and may have reached lengths over 100 feet, with fossils including massive vertebrae from New Mexico and Texas.
What is Alamosaurus?
This duck-billed hadrosaur from the Cretaceous had a long, curved crest on its head that may have been used like a trumpet to make loud calls.
what is parasaurolophus
This massive sail-backed theropod from Early Cretaceous Africa was likely semi-aquatic, using its long snout and conical teeth to catch fish like a giant crocodile.
What is Spinosaurus?
This intelligent troodontid from Late Cretaceous North America had large eyes, a big brain, and evidence of eating seeds, small prey, and possibly fruits as an opportunistic omnivore.
What is Troodon?
Once mistakenly called Brontosaurus, this massive Jurassic sauropod had a thick neck and is now officially recognized again as a distinct genus.
What is Apatosaurus?
This massive European sauropod from the Late Jurassic of Spain, one of the heaviest known from that continent, had a robust build and primitive features blending macronarian and diplodocoid traits, with estimates placing it around 30-39 meters long.
What is Turiasaurus?
This heavily armored tank-like dinosaur from the Late Cretaceous had bony plates covering its body and a clubbed tail that could smash predators.
What is Ankylosaurus?
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?
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?
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?
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?
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 Nigersaurus?
This bizarre abelisaurid from Late Cretaceous Madagascar had a domed skull, tiny arms, and evidence of cannibalism, with unusually serrated teeth adapted for slicing rather than crushing.
What is Majungasaurus?
This pot-bellied therizinosaurid from Late Cretaceous Mongolia, famous for its absurdly long 3-foot claws, was primarily herbivorous but supplemented its diet with fish, insects, and small animals, as shown by its gut contents and tooth structure.
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?
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.
What is Europasaurus?
