Apatosaurus, meaning "deceptive lizard" in Greek, was a giant, plant-eating sauropod dinosaur that lived in North America and Europe during the Late Jurassic period.
**145 Million BC, Late Jurassic Period**
*Horsetails were sprouting amongst the forest, perfect for a very hungry apatosaurus, who was munching on these greens. It didn’t seem to pay attention to its surroundings thanks to its large size to intimidate predators.*
