Mammals evolved from a group of mammal-like reptiles called the Synapsids, specifically the Therapsids, in the Triassic period, around 250 million years ago.
The more evâ¦idence that we find, the less sure we are that 'dinosaurs' evolved into only one form of life. Birds may in fact be the descendants of a 'maniraptoran' dinosaur. However it is not known at this time if other forms of dinosaurs evolved into other animals that we have today. Crocodiles, alligators and tuatara are all descended from species which would now be termed dinosaurs.
