In the video, the paleontologist discovered the new fossils by looking in the area.Suppose the inhabitants of a previous site dug a large hole.The top of the heap of excavated dirt would date the oldest.

In archaeological sites, natural and human-generated materials occur together in layers. But absolute dating methods are not always useful; the particular circumstances to which they apply do not exist at every site. Dating methods, such as radiocarbon dating, dendro-chronology or tree-ring dating, and potassium-argon dating, that may furnish an date for an archaeological site, are a contribution of the physical and the natural sciences.They will excavate a hypothetical archaeological site from their school yard, make observations, and write an interpretation of the history of the area based on the evidence they will excavate.To facilitate the activity, the teacher will provide some introduction to absolute dating principles through the Half Life of M&M Worksheet.Discuss that the changes that have occurred on Earth including the terrain, temperature, landforms and organisms make it difficult to predict where dinosaurs may be found.
