Types of Fossils

Science · Dinosaurs & Paleontology · conceptual

Distinguish body fossils (preserved bones, teeth, shells) from trace fossils (footprints, trackways, eggs, burrows, coprolites) and explain what each type can tell scientists

What mastery looks like

  • Sort examples into body fossils (bones, teeth, shells) and trace fossils (footprints, eggs, dung)
  • Explain that body fossils show what an animal looked like physically
  • Explain that trace fossils show how an animal behaved — how it moved, what it ate, where it nested

Check your understanding

If Types of Fossils saw a dinosaur footprint in rock at a museum, could they explain how it's different from a fossil bone and what scientists can learn from it?
