What are two ways to date fossils?
Two ways to date fossils are relative dating, which involves determining the age of a fossil in relation to other fossils or geological layers, and absolute dating, which provides a numerical age for a fossil using techniques like radiometric dating.
What is the principal of paleontological identity?
The Principle of Paleontological Identity is the theory that the layers of sedimentary rocks around the world can be dated by the fossils which they contain. Based on this theory, two layers having the same fossils are regarded as having the same age. This principle is based on the existence of stratigraphic fossils. It is taken in theory to make it possible to correlate sedimentary sequences in distant areas from each other.
What are two best environments to look for fossils?
Two of the best environments to look for fossils are sedimentary rocks, such as riverbeds and cliffs, and areas with volcanic activity as ash and lava can preserve fossils well. Additionally, coastal regions with eroding cliffs or beaches can also be good places to find fossils.
What are two kinds of information that scientists attempt to infer from the study of fossils?
Relative age of the rocks and the Paleo environment.
What are two kinds of fossils?
Two kinds of fossils are body fossils, which preserve the actual remains or impressions of an ancient organism, and trace fossils, which are indirect evidence of an organism's activity, such as footprints or burrows.
Why is it important for paleontologists be experts in both anatomy and geology?
Paleontologists need to have a working knowledge of geology to recognise not only which rock is best to search for fossils but also to recognise fossils from the surrounding rock. They need to have a working knowledge of anatomy (biology) to recognise what part of the animal or plant they are looking at.
What Two things that paleontologists can learn from fossils?
one that they can learn there definitely was life before and 2 that our ancestors developed to form us humans
How do Paleontologists use the remains of the Trilobites?
Paleontologists use the fossils of different aged trilobites to identify the age of rock formations and fossils in other locations. Similar trilobites found in British Columbia as found in Asia would indicate the rock was nearly the same age from both sites. May also mean that the two locations were once close together, but moved away due to plate tectonics.
What are the two ways of dating fossils explain both?
carnivore
What are two of determining a fossils age?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
What are two ways of using fossils to date organisms?
superposition and carbon dating
What is a scientist called who studies rocks and fossils?
Strictly speaking these are two differing types of scientists. Petrologists study rocks and paleontologists study fossils. However both these disciplines are covered in the broader training of a geologist.
What are two ways to date fossils?
Two ways to date fossils are relative dating, which involves determining the age of a fossil in relation to other fossils or geological layers, and absolute dating, which provides a numerical age for a fossil using techniques like radiometric dating.
What two ways do scientist use fossils to determine the environmental changes?
its radioactive dating and relative dating

What are the two ways to date a fossil?
Radioactive isotope dating (potassium, argon) and relative dating, comparing with fossils of the same characteristics with known dates. Particularly if they are known to be 'zone fossils'
