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.

Do reptiles have flat grinding teeth?
No, reptiles typically have sharp, pointed teeth for gripping and tearing food, rather than flat grinding teeth like mammals. Some herbivorous reptiles may have more flattened teeth for crushing plant material, but they are not true grinding teeth like mammals.
Which has more teeth mammal or reptile?
Typically, mammals have more teeth than reptiles. Mammals generally have specialized teeth for different functions such as cutting, tearing, and grinding food. Reptiles, on the other hand, may have fewer teeth or even be toothless, depending on the species.
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.
Are reptiles more closely related to mammals or to fishes?
Reptiles are more closely related to mammals than to fishes. Reptiles and mammals are both part of the group called amniotes, characterized by their ability to lay eggs on land. Fish, on the other hand, are a separate group with distinct evolutionary lineages from reptiles and mammals.
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.
Why do mammals lose more heat energy than reptiles?
Mammals have higher metabolic rates than reptiles, which means they generate more heat internally. This excess heat needs to be released to maintain a stable internal temperature, so mammals lose more heat energy through mechanisms like sweating, panting, and shivering. Reptiles have lower metabolic rates and can rely on external sources of heat, like the sun, to regulate their body temperature.
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.
