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.
Dinosaurs are reptiles, not mammals. They belong to a distinct group of reptiles called archosaurs and are not closely related to mammals.
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.

Did mammals appear in the fossil record before dinosaurs or after?
Mammals appeared in the fossil record before dinosaurs, with the first mammal-like reptiles evolving around 300 million years ago. Dinosaurs evolved later and became dominant during the Mesozoic Era, while mammals diversified and evolved into various forms alongside dinosaurs.
Most mammals during the Mesozoic were?
During the Mesozoic Era, most mammals were small, nocturnal, and likely insectivorous. They were overshadowed by larger reptiles like dinosaurs and did not become the dominant group of animals until after the extinction of the dinosaurs at the end of the Mesozoic.
What is a nickname for the mesozoic era?
"Age of the dinosaurs" is a common nickname for the Mesozoic Era because it was a period when dinosaurs dominated the Earth.
Did early mammals cause the extinction of dinosaurs?
No, early mammals did not cause the extinction of dinosaurs. The extinction of dinosaurs is believed to have been caused by a combination of factors, such as a large asteroid impact and volcanic activity, which led to drastic environmental changes that the dinosaurs could not survive. Mammals actually flourished and diversified after the extinction of the dinosaurs.
Were all dinosaurs reptiles?
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,
Are humans small dinosaurs?
no dinosaurs were reptiles and we are mammals.
Did mammals evolve from dinosaurs?
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.
Do you believe that dinosaurs were ever mammals?
No. Dinosaurs are currently considered reptiles and are not related to mammals.
Did mammals or reptiles develop first?
reptiles because of the dinosaurs
Were dinosaurs mammals or amphibians?
Neither...They were reptiles. dinosaurs were nether amphibians or mammals they were all reptiles, though they are more closely related to birds.
Are dinosaurs the oldest mammals?
No. Dinosaurs were not mammals. They were more closely related to birds and modern reptiles than they were to mammals.
Why aren't dinosaurs 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.
Are dinosaurs related to mammals?
No, dinosaurs are more related to reptiles and birds.
Are people mammals or reptiles?
There are more mammals because of the dinosaurs.
Is there a possibility humans evolved from dinosaurs?
Nope, humans are mammals. Mammals emerged shortly after the dinosaurs did, evolving from a very distant group of reptiles.
Did dinosaurs have sweat glands?
Only mammals have sweat glands. Dinosaurs were reptiles, so they did not have sweat glands.
How many dinsaurus are mammals?
No dinosaurs were mammals, but reptiles. "dinosaur" means "terrible lizard." Though there may be a link between dinosaurs and modern birds.
