An Archaeopteryx may have been able to fly, but a plesiosaur is a swimming reptile, and it doesn't fly. Archaeopteryx could not fly is was too heavey and its wings were way too short to support flight and as for the plesiosaur as the previous person mentioned it was a swimming reptile
The name means 'winged and toothless'.
they fly about 45mph and walk 2mph
It flies. But it is hard for it to fly. To fly, it still needs to climb a tree and then jump.
It was not a dinosaur, but a plesiosaur and the longest plesiosaur. It could grow upto 15 m long.
Easy! The best example is an Archaeopteryx. Pterodactyls and Pternadons are others but there is some debate that they actually glided instead of flying.
It could be described as the first bird.
actually no dinosaurs ever flew. pterodactyls and the often called dinobird archaeopteryx were ancient flying creatures, but none of them are classified as dinos.
Archaeopteryx had claws on its wings, a long tail, and a toothed beak. These are all considered reptilian traits.
The plesiosaur ate mostly fish and plants
well Darwin knew that reptiles could change into birds and an archaeopteryx is basically a reptile with wings
Archaeopteryx was a vertebrae. It had a backbone
the archaeopteryx is in the aves class
An archaeopteryx is an early form of the bird. The scientists discovered an archaeopteryx fossil.
