A reptile is in no way a mammal. A reptile is a vertebrate, but it is completely different from a mammal. It doesn't have hair, it is an ectotherm, and it doesn't feed its young with milk. A mammal has hair at some point in its life, is an endotherm, and feeds it's young with milk.
They are reptiles because they are cold-blooded, lay eggs and have scales.
Turtles are reptiles because they are cold blooded as are all reptiles and they do not have hair or produces milk for their young like mammals do.
they were cold-blooded reptiles, though emerging evidence suggests they were warm blooded.
Dinosaurs are technically classed as reptiles. They were not related to mammals, but were more closely related to birds.
No, we are mammals.
Humans are mammals

Mammals actually first came into existence about 220 million years ago, which is about 155 million years before the dinosaurs went extinct, and only about 10 million years after they themselves first evolved. So mammals actually lived alongside the dinosaurs, though played a much smaller role.
No. Turtle are from a branch of reptiles completely separate from dinosaurs.
No way! There were thousands of species of reptiles that lived both during, before, and after the dinosaurs lived on earth. There were the synapsid reptiles, as well as the anapsid reptiles, which were mostly gone when the dinosaurs arrived. There were also many diapsid reptiles that lived during the time the dinosaurs did. Such species include deinosuchus, dimetrodon, gorgonops, Quetzalcoatlus, and rutiodon. Dinosaurs were not reptiles themelves. They evolved from reptiles, many had warm blood even feathers,
The first dinosaurs lived in the beginning of the Mesozoic Era (or the Age of Reptiles). Birds were amazingly discovered to be dinosaurs so dinosaurs were also alive in the Cenozoic (that's our time-the Age of Mammals) to today.
No. By the time the dinosaurs went extinct mammals still played a relatively minor role ecologically. It is generally accepted that an asteroid or comet struck the earth, causing ecosystems to collapse worldwide and resulting the extinction of many groups of animals including the dinosaurs.
no dinosaurs were reptiles and we are mammals.
No. Mammals evolved from synapsid reptiles, a group not closely related to dinosaurs. Dinosaurs are more closely related to modern reptiles and birds than they are to mammals.
No. Dinosaurs are currently considered reptiles and are not related to mammals.
reptiles because of the dinosaurs
Neither...They were reptiles. dinosaurs were nether amphibians or mammals they were all reptiles, though they are more closely related to birds.
No. Dinosaurs were not mammals. They were more closely related to birds and modern reptiles than they were to mammals.
Dinosaurs and mammals evolved from two separate branches of reptiles. Mammals evolved from synapisid reptiles (all of which are not extinct) while dinosaurs along with the modern branches of reptiles evolved from sauropsids. So dinosaurs are more closely related to modern reptiles than they are to mammals. In more recent years scientist tend to agree that birds are in fact a surviving branch of dinosaurs.
No, dinosaurs are more related to reptiles and birds.
There are more mammals because of the dinosaurs.
Nope, humans are mammals. Mammals emerged shortly after the dinosaurs did, evolving from a very distant group of reptiles.
Only mammals have sweat glands. Dinosaurs were reptiles, so they did not have sweat glands.
No dinosaurs were mammals, but reptiles. "dinosaur" means "terrible lizard." Though there may be a link between dinosaurs and modern birds.
