If a fossil is encased in a stratum of sedimentary rock without any strata of igneous rock (e.g., lava, volcanic ash) nearby, then it should be

#SCPH28 | Zoology

  1. easy to determine the absolute age of the fossil, because the radioisotopes in the sediments will not have been ʺresetʺ by the heat of the igneous rocks.

  2. easy to determine the absolute age of the fossil, because the igneous rocks will not have physically obstructed the deposition of sediment of a single age next to the fossil.

  3. difficult to determine the absolute age of the fossil, because the ʺmarker fossilsʺ common to igneous rock will be absent.

  4. difficult to determine the absolute age of the fossil, because radiometric dating of sedimentary rock is less accurate than that of igneous rock.
