The earliest dinosaurs resembled two-legged, short-headed crocodiles, but later dinosaurs were oddly reminiscent of giant mammals and birds.
It's easy to tell a dinosaur skeleton from that of a modern reptile because dinosaur skeletons have a strong joint between the backbones and hips.
Small, two-legged dinosaurs could turn rapidly by swinging their tail abruptly in a direction opposite to where they wished to turn.
Some dinosaurs had feathers.

Not all bats are nocturnal – some are active during dawn and dusk. To get around in the dark and find their prey, many bats rely on a sophisticated form of sonar known as echolocation. Many bats, especially the crepuscular ones, have exceptionally good eyesight designed for low levels of light.
