There are a number of reasons for the relatively few mammal fossils compared to others such as invertebrates.
Mammals have been around for about 220 million years, much less than others.
Most mammals are land animals whereas the best place to be preserved as a fossil is in sediment in seas or lakes.
Mammals tend to be small in earlier times, which means their bone are small and fragile.

What is the evidence of seafloor spreading?
Animal fossils have been found in many places in the ocean.
What kind of fossils are found in South America and South Africa?
it was the Cynognathus. Cynognathus is an extinct mammal-like reptile. The name literally means 'dog jaw'. Cynognathus was as large as a modern wolf and lived during the early to mid Triassic period (250 to 240 million years ago). It is found as fossils only in South Africa and South America.
What are fossils commonly found in?
Fossils are the remains of an animal that have been preserved in rock. This process is called fossilization. They are commonly found all over the world, but many fossils are found where ancient seas that have dried up, like the Badlands. Other fossils are found where an animal died and was eventually buried under fossilized dirt, mud, or even sand. any creature with an exoskeleton or endoskeleton can be fossilized. But most creatures in the Precambrian and Archean Periods were not fossilized because of their lack of a skeleton. Jellyfish will also just dissolve when dead.
What generally happens to the remains of a plant or animal when it dies How does this help explain which parts of plants or animals usually form fossils?
When a plant or animal dies, its remains decompose, but sometimes they can become preserved in sedimentary rock or hardened resin, forming fossils. Hard parts like bones, shells, and teeth have a better chance of becoming fossilized compared to soft tissues, which decay more quickly. This is why fossils of hard parts are more commonly found in the fossil record.
Plant and animal fossils are most often found in metamorphic rock?
Actually, plant and animal fossils are most commonly found in sedimentary rocks rather than metamorphic rocks. This is because sedimentary rocks are formed from the accumulation and compression of sediments that can entomb and preserve plant and animal remains over time. Metamorphic rocks, on the other hand, are formed from the alteration of existing rocks under high pressure and temperature conditions, which usually destroys any fossils present.
Are mammal fossils found in rock?
Yes, mammal fossils can be found in rocks. They are typically found in sedimentary rocks, such as limestone or shale, where the remains of ancient animals have been preserved over time. These fossils provide important insights into the evolution and history of mammals.
What types of fossils are most likely to be found?
fish fossils and little animal fossils and also shells
What types of rocks are fossils most likely to be found?
fish fossils and little animal fossils and also shells
What rock are most marine animal fossils in?
The most marine fossils are found in sedimentary rock
What is the main animal found in grassland?
The main grassland large mammal is the human
What do fossils teach about extinction?
The kind and numbers of fossils found in different kinds of rocks give clues about past ecosystems. Fossils give evidence that, in any ecosystem, some plants and animals survive well, and some do not.
How do you know dinosaurs and mammals were coexistent?
Fossils of dinosaurs and mammals have been found in the same strata. Mammal bones have been found in the stomachs of some predatory dinosaurs.
What is the evidence of seafloor spreading?
Animal fossils have been found in many places in the ocean.
Can animal droppings be fossilized?
Yes, there have been many such fossils found and they are named Coprolites.

Fossils are found mainly in- - - rock?
Limestone and sandstone. The rock needs to be one that's formed from sedimentation around the dead animal.
