How is a reptile skull different from a mammal skull?

Answer 1

Mammals are warm-blooded, have fur, feed their young milk, and usually give birth to live young. Reptiles are cold-blooded, have scales, usually lay eggs, and generally do not feed their young.

Answer 2

Mammals are warm blooded; reptiles are colblooded. All mammls have hair on their body (including humans); while reptiles usually have scales. Mammals are born live (WITH! the exception of the playtapus); reptiles are hatched.

Answer 3

At the posterior end of the skull, near the Foramen magnum (where the spinal chord and skull interact) Mammalian skulls bear two occipital condyles (two swellings of bone) This allows for better mobility. Mammal's lower jaw is composed of only one dentary bone on each side. Mammal's teeth are deciduous, or diphyodont, meaning they have two sets (milk or baby teeth, which fall out to give way to adult or permanent teeth). There are more subtle differences, but those are the main ones.

Answer 4

Reptile skulls typically have fenestrae (openings) behind the eye socket, while mammal skulls do not have these openings. Additionally, reptiles often have more joints in their skulls compared to mammals, allowing for more flexibility and movement. Mammals generally have a secondary palate, separating the nasal cavity from the mouth, while reptiles do not.

Answer 5

Reptiles have a three-chambered heart, mammals a four-chambered.

Answer 6

Reptiles are cold blooded and most give birth in eggs.
