The image below shows two fossil samples. 2.1.1 Identify (a) Fossil X (b) Fossil Y. 2.1.2 Name TWO other ways that fossils are formed, other than in sedimentary rock. 2.1.3 What is the method called that scientists use to date fossils with radioactive isotopes like carbon-14 or potassium-40?

2.1.1 a) Fossil X: Trilobite b) Fossil Y: Ammonite 2.1.2 Two other ways fossils are formed, other than in sedimentary rock, are: • Preservation in amber (fossilized tree resin). • Preservation in ice. 2.1.3 The method called that scientists use to date fossils with radioactive isotopes like carbon-14 or potassium-40 is radiometric dating.
