Dryosaurus, the "Tree Lizard," was
a speedy, little creature from the
late Jurassic that fans find
endearing due to its adorable looks. 
With a maximum legnth of about four 
meters and a height of two meters, 
dryosaurus was on the smaller side
during a time of titans. These small
creatures required a well-built body
to remain away from the wide maws of 
predators. Its strong legs made it a
swift runner, and its stiff tail
served as an effective counter-
balance that allowed it to be 
incredibly agile. Considering the 
dangerous carnivores of the time, 
dryosaurus'speed was quite necessary 
to evade the likes of ceratosaurus 
and allosaurus.

Scampering across semiarid the
environments of what is now the
western United States, dryosaurus 
lived in forested habitats near 
rivers and floodplains alongside 
many famous titans, such as 
diplodocus and stegosaurus. While
the mighty sauropods fed upon high 
vegetation, dryosaurus elected to 
browse lower hanging plants for 
sustenance. Like other ornithopod 
dinosaurs, it had a beak on its 
mouth that assisted in chewing plant
matter; in addition, its cheek 
structure allowed it to hold food in
its mouth while chewing, like human 
cheeks, preventing any unnecessary 
food loss.
