Yes, mammals have more teeth that reptiles. The land mammal with the most teeth is the Giant Armadillo (Priodontes giganteus) with as many as 100 teeth. The average range for mammals however is 20-40. Reptiles rarely have many teeth, if any at all. The crocodile has the most, with around 80 teeth at a time. It replaces as many as 3000 in its lifetime, but this is over a long period of time.

How do paleontologists distinguish between fossils of mammals and reptiles?
There are a variety of features but one is the number of fenestrae in the skull. Mammals also have more differentiated teeth than reptiles. Furthermore, you can look at the gait. Mammals have a parasagittal stance, while most reptiles have a sprawled stance.
Why do mammals lose more heat energy than reptiles?
mammals tend to have heat in their bodies more than their surroundings
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.
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.
Are mammals more popular than non mammals?
No, I don't know exact numbers but mammals are outnumbered greatly by fish, reptiles & insects
Do all mammals have more than sixteen teeth?
Not all animals do.
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.
Why do mammals need more oxygen than reptiles?
Mammals maintain a higher body temperature. In order to do so, they require more energy and that requires more oxygen.
What is bigger mammal or reptile?
There are individual mammals that are bigger than individual reptiles, and there are individual reptiles that are bigger that individual mammals. However, the average size of all extant mammals is larger than the average size of all extant reptiles. Most reptiles are lizards and snakes, which are usually small. Only a few species of tortises, alligators, crocodiles, caimans, and very large snakes are big. Most mammals are bats, rodents, and shrews, which are usually small, but there are still hundreds of mammals that are big, including the biggest animal on the planet: the blue whale. There are more large mammals than there are large reptiles.
Are mammals related to birds?
Mammals are distantly related to birds. Oddly, if you look at an evolutionary tree, birds are actually more closely related to reptiles than they are to mammals.
Is an egret a mammal or a reptile?
Birds are neither mammals, nor reptiles. They are an entirely different branch of evolution. However, they are more closesly related to reptiles, which they descended from. Their evolution from reptiles caused them to resemble mammals.
What enables mammals to live in colder environments than reptiles?
Fur and a layer of fat beneath mammals skin enables mammals to live in colder environments than reptiles because the amount of fur that covers a mammal's skin varies greatly like animal that live in cold region have more fur than animal that live in warmer environments.hope this helps!!
