What are two ways of using fossils to date organisms?
superposition and carbon 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'
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 paleontologists age of fossils?
Paleontologists age fossils primarily through relative dating and radiometric dating. Relative dating involves determining the age of a fossil based on its position in sedimentary rock layers, using the principle of superposition, where younger layers are deposited on top of older ones. Radiometric dating, on the other hand, measures the decay of radioactive isotopes within the fossils or surrounding rocks, providing a more precise numerical age. Together, these methods help build a timeline of the Earth's biological history.
What are two ways geologists determine the age of fossils?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
What are three types of radiometric dating?
Three types of radiometric dating are carbon-14 dating, uranium-lead dating, and potassium-argon dating. These methods are used to determine the age of rocks and fossils by measuring the decay of radioactive isotopes into stable isotopes over time.
How do scientist use radioactive elements to determine the actual age of fossils?
scientist can determine a fossil's age in two ways: relative dating and absolute dating
How the age of fossils of plant and animals etc is determined?
well it mostly depends on the ways and types 1) the logical approach- in this the things (fossils) you find deeper will be more older than the one found on the surface. 2)the constituent study- the method work by calculating the number of isotopes of an element present in the fossil 3)carbon dating - estimating the number of cabon14 isotope.
List several ways in which fossils can be made?
Fossils can form by: Freezing Amber Asphalt Carbonization
What two types of dating techniques are used in dating fossils?
Body fossils and trace fossils are the principal types of evidence about ancient life, and geochemical evidence has helped to decipher the evolution of life before there were organisms large enough to leave fossils. Estimating the dates of these remains is essential but difficult: sometimes adjacent rock layers allow radiometric dating, which provides absolute dates that are accurate to within 0.5%, but more often paleontologists have to rely on relative dating by solving the "jigsaw puzzles" of biostratigraphy.Classifying ancient organisms is also difficult, as many do not fit well into the Linnean taxonomy that is commonly used for classifying living organisms, and paleontologists more often use cladistics to draw up evolutionary "family trees". The final quarter of the 20th century saw the development of molecular phylogenetics, which investigates how closely organisms are related by measuring how similar the DNA is in their genomes. Molecular phylogenetics has also been used to estimate the dates when species diverged, but there is controversy about the reliability of the molecular clock on which such estimates depend.
