"Birds" are a clade; a group of related species. In particular, they're members of the class Aves.
The smallest clade that envelops both dinosaurs (including birds) and crocodiles is Archosauria. This clade first emerged between 260 and 250 million years ago.
AnswerYes, birds are animals.
An avialan is an animal belonging to the clade Avialae, including all birds, and the airborne dinosaurs from whom they evolved.
Pterodactyls never turned into birds. The whole clade Pterosauria went extinct at the end of the Cretaceous, and birds evolved from theropod dinosaurs some 150 million years ago, during the Jurassic.
What most people call "flying dinosaurs" were actually pterosaurs, flying reptiles that were unrelated to dinosaurs. However, birds are considered by most scientists to be a clade of dinosaurs, and thus birds are "flying dinosaurs."

The scientific classification of sampaguita is: Kingdom: Plantae Clade: Tracheophytes Clade: Angiosperms Clade: Eudicots Clade: Asterids Order: Gentianales Family: Rubiaceae Genus: Jasminum Species: Jasminum sambac
The classification (taxonomy) of birds involves grouping of birds into categories according to physiological similarities, and more recently, by consideration of their genetic make-up.Kingdom: Animalia Phylum: Chordata Superclass: Tetrapoda Clade: Eumaniraptora Clade: Avialae (Gauthier, 1986) Class: Aves (Linnaeus, 1758)
One clade of dinosaurs, the theropods, were carnivorous. Many of them were large and ate other dinosaurs. Today, birds are the only surviving group of dinosaurs. Some birds of prey eat other birds, so dinosaurs still eat other dinosaurs today.
