Birds and Dinosaurs
Though we think of dinosaurs as being extinct, recent research suggests that their
modern relatives live among us in the form of birds. Like birds, many dinosaurs built
nests, laid eggs, and had feathers. Over the last twenty years, scientists have collected
more and more evidence suggesting that dinosaurs evolved into birds. For example,
thousands of fossils of dinosaurs with feathers have been found in China, and fossilized
dinosaur eggs are similar in size and shape to birds' eggs. Fossils have also revealed
information about dinosaurs' skeletons. Birds have hollow bones to enable flight, and SO
did some dinosaurs. In addition, birds and dinosaurs exhibit many similarities in their
legs, feet, and claws.
