Note; it only works for sedimentary rocks ... but if you know approximately how long ago that type of animal lived, then you know about when the rock began to form around it (to form the fossil).

∙ 13y ago- The appearance or disappearance of types of organisms throughout Earth's history marks important occurrences in geologic time. Paleontologist have been able to divide Earth's history into time units based on the life-forms that have lived only during certain periods the division of Earth's history makes up the Geological Time Scale.

What sedimentary rock often has fossils?
Paleontologists are looking for fossils in sedimentary rock.
Which type of rock may contain fossil?
fossils almost allways occur in sedementary rock. this is the only way to get fossils without burning or cruching the fossil. you sometimes get fossils in igneous rock, but this is very rare. igneous rock fossils do not have any actual "fossils" in them, they are just impressions.
What are index fossils and how are they used to determine the absolute age of sedimentary rock?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
Dating technique involving compraring fossils in rock layers?
Relative dating-comparing fossils related to how old other fossils are in the same sample of rock. If the rock has been undisturbed, the oldest rock will be at the bottom, therefore, the oldest fossils will also be at the bottom. the youngest rock will be at the top, therefore, the youngest fossils will be at the top. Absolute Dating-When you can figure out through testing the exact age of the fossil
Are mammal fossils found in rock?
Fossils of animals and plants can be found in sedimentary rock (limestone, chalk, slate, etc).
What is the difference between chalk and coal?
Chalk is a rock composed of animal fossils and coal is a rock composed of plant fossils.
What is the relationship between sedimentary rocks and fossils?
When sedimentary rocks grow more layers small fossilised animals get caught between the layers. Ther fore when people chip away at the rock or erosion happens the fossilisd animals have been turned into fossils and fall out.
What kind of rocks would you find fossils in and why?
Fossils are found in sedimentary rock because it is layers of sand, rock, and sediments, and the bones fall between the layers where the form into fossil's.
Are there any fossils in wave rock?
yes there are fossils in wave rock
What type of rock do you fine fossils?
fossils are fine in metamorphic rock
Why do rock fossils form in sedimentary rock and not in igneous rock-?
Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.
Type of rock in which most fossils are found?
Sedimentary rock is where we look for fossils.

I can say that fossils are bone
What is the term for the remains for the remains of things found in a rock?
