    Birds may very well descend from earlier dinosaurs.  Birds have been around for more than 150 million years so if they are descended from dinosaurs, it had to be ones before that.  I think it is quite likely that birds evolved better respiratory, circulatory, muscles, bones etc as adaptation to flight.  These features became useful to land predators and many of the most closely related animals to birds are the later theropods including velociraptor and T. rex.  These animals could not have evolved into birds but it is possible that they have a bird ancestor.  At any rate, the general consensus is that birds are a type of dinosaur.    Mammals are separate from dinosaurs and both dinosaurs and mammals evolved separate from each other.  Birds are certainly the only living animal evolved from a dinosaur.

    Although birds are thought to be the only living dinosaur descendants, some other animals living today are related to the dinosaurs. Dinosaurs are in the reptile group, which includes turtles, crocodiles, birds, lizards, and snakes.

    Dinosaurs are an evolutionary dead end. They have zero living descendants. People who claim that birds evolved from a dinosaur are dead wrong. Feathered dinosaur is the biggest hoax in the history of paleontology, and possibly the worst hoax in the history of science. So-called feathered dinosaurs such as Anchiornis and Microraptor are actually feathered birds. the "feathers" or "protofeathers" found on the skin of some dinosaurs such as Sinosauropteryx are most likely collagen fibers. The most likely ancestor of birds is Longisquama insignis, the only known reptile that has feathers that are homologous to avian feathers. People who have been telling the world that birds evolved from a dinosaur for the last quarter of a century simply do not want to admit that they are wrong because it would do their career serious damage. So they will keep saying that birds evolved from a dinosaur until the day they croak, even though there is a mountain of evidence that birds did NOT evolve from a dinosaur.

    Mammals did not evolve from a dinosaur either. Mammals evolved from a therapid reptile. Therapsids in turn evolved from a synapsid reptile. Therapsid and synapsid reptiles are a different evolutionary branch than the dinosaurs. Dinosaurs are more closely related to crocodilians and lizards than they are to mammals. In fact, mammals may well be more closely related to turtles than they are to dinosaurs or lizards.

    Birds aren't mammals, unless you want to credit bats as birds. Likewise dinosaurs aren't mammals.
