Fossils and Their Significance

The video tutorial covers the use of fossils as evidence of past ecosystems and environments. It explains what fossils are, how they form, and the different types of fossils. The lesson distinguishes between paleontologists and archaeologists, emphasizing the study of fossils to understand Earth's history. The law of superposition is introduced to explain the dating of fossil layers. The tutorial also guides students on interpreting fossil layers to deduce past environments. Additional resources and activities are provided for further exploration.
