Fossils: We’re Digging It!
Fossils are fundamental to discovering information about the past inhabitants of Earth over the course of its 4.5 billion year history. Along with learning about the geological time of the Earth, students also learned about the different types of fossils and how they give us insight into the past. We briefly explored the various types of fossils that can be found, including body fossils (cast, petrified wood, or whole body) that tell us what organisms looked like, and trace fossils (footprints, and coprolites) that tell us how an organism lived. Students discovered that stromatolites (made from bacteria) are the first and oldest fossils on the planet. Students were then turned into paleontologists, as they were able to excavate their own dinosaur bone fossils from a rock using tools and techniques similar to those employed by paleontologists and reassemble their dinosaur skeletons.
