Basis of mammal classification?
Basis of mammal classification?
Based on a combination of factors including soft anatomy, skeletal structure, and molecular data.
Why teeth, jaws, skulls fossilize well?
Why teeth, jaws, skulls fossilize well?
Teeth, jaw bones, and skulls are denser and more resistant to physical and chemical weathering than other body parts.
Why is the mammal fossil record good?
Why is the mammal fossil record good?
Mammalian teeth enamel contains crystalline apatite which is highly resistant to weathering providing a detailed fossil record.

Study Notes
Classification of Mammals
- The basis of the classification of mammals is not specified, but various characteristics, such as dental features, are used to interpret mammalian relationships and phylogeny.
Fossil Record of Mammals
- Teeth, jaw bones, and skulls are the most common remains of mammals found in the fossil record due to their durability and resistance to physical and chemical weathering.
- The fossil record of mammals is better than that of other major vertebrate groups, but the reasons for this are not specified.
Contributions of Recent Disciplines
- Recent disciplines like serology and genetics have contributed to the classification of mammals, but the specifics of their contributions are not detailed.
Characteristics of Mammalian Teeth
- Mammalian teeth are highly resistant to physical and chemical weathering due to their enamel coating.
- The characteristic that makes mammalian teeth unique is not specified.
Paleontological Findings
- Paleontological findings have supplemented the classification of living organisms, but the specifics of their contributions are not detailed.
Subclasses of Mammals
- The subclass of mammals that produces young ones that develop inside the mother's body is the Theria.
- The order of Marsupalia is an example of a Metatheria mammal.
- A characteristic of Prototheria mammals is that they lay eggs.
Characteristics of Mammals
- A characteristic that sets mammals apart from other species is the presence of mammary glands.
- The function of mammals' mammary glands is to produce milk to nourish their young.
