Fossilised Dinosaur Dung

Science · Dinosaurs & Paleontology · conceptual

Describe what coprolites are (fossilised dinosaur dung) and how palaeontologists analyse them to discover what dinosaurs ate, including plant fragments, bones, and seeds

Sign in to track this

What mastery looks like

  • Define a coprolite as fossilised dung (animal droppings preserved as rock)
  • Explain that scientists cut coprolites open to find plant seeds, bone fragments, or fish scales inside
  • State one example of what coprolite contents reveal about a dinosaur's diet

Check your understanding

Does Fossilised Dinosaur Dung know what a coprolite is? Can they explain — with a giggle — how fossilised poo helps scientists figure out what a dinosaur ate?
