Birds have been said to be descended fromcertain birdlike dinosaur species with which they share distinctive structural features.

birds and birdlike dinosaurs.
(C) There are no birdlike dinosaur fossils thatare older than the bird fossils but have not yet been
unearthed. （选C）

dinosaur species and other birds from another.
