The age of the fossil must be determined so it can be compared to other fossil species from the same time period.

Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms.

Learn how inclusions and unconformities can tell us stories about the geologic past.

We'll even visit the Grand Canyon to solve the mystery of the Great Unconformity!

Ph ET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery.

PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.

Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years.By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.Although most attention in today's world focuses on dinosaurs and why they became extinct, the world of paleontology includes many other interesting organisms which tell us about Earth's past history.The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.Now imagine that you come upon a formation like this: What do you think of it? How can you make any conclusions about rock layers that make such a crazy arrangement?
