Journey back millions of years to the age of giant reptiles! Explore dinosaurs like Coelophysis, T-Rex, and Brachiosaurus, plus the flying reptile Pteranodon. Filter by Triassic, Jurassic, and Cretaceous eras, and test your paleontology skills in fun quizzes.
“King of the Tyrant Lizards”
Dinosaur
Massive bone-crushing jaws with a bite force of 12,000 pounds and 50 serrated teeth up to 30 cm long.
T-Rex had keen stereoscopic eyesight and an acute sense of smell better than a bloodhound's.
Mesozoic eras, dinosaur diets, fossil anatomy, and paleontology science tips.
The age of dinosaurs spanned 180 million years across three periods: Triassic (dawn of first dinosaurs), Jurassic (giant sauropods), and Cretaceous (T-Rex and Triceratops).
Herbivores like Triceratops and Stegosaurus evolved defensive armor and battery teeth to eat plants, while Carnivores like T-Rex evolved lethal claws and bone-crushing jaws.
When a prehistoric animal died near water, mud and sediment covered its skeleton. Over millions of years, minerals replaced bone cells to form stone fossils.
Paleontologists proved that modern birds are direct avian dinosaur descendants: many theropods like Velociraptor had colorful real feathers.
Bury plastic dinosaur bones in a bin of sand and use paintbrushes to uncover them like real field paleontologists.
66 million years ago, a 10-kilometer asteroid struck Mexico's Yucatan peninsula, ending the reign of non-avian dinosaurs.

It is a free interactive paleontology workbench for beginners to discover dinosaur species, Mesozoic eras, diets, and fossil anatomy.
The three periods are the Triassic Period (252-201 Ma), Jurassic Period (201-145 Ma), and Cretaceous Period (145-66 Ma).
Pteranodon was a flying reptile (pterosaur) that lived alongside dinosaurs during the Cretaceous, but belongs to a sister reptile group.
Yes, fossil discoveries in Mongolia show quill knobs on Velociraptor forearm bones, proving it was covered in real plumage feathers.
Its 9-meter neck and tall front legs allowed it to graze on the highest gymnosperm and conifer treetops that other herbivores could not reach.
Practice mode offers three self-paced quizzes: sorting dinosaur diets, identifying geological eras, and solving fossil detective clues.
