Reconstructing Ancient Ecosystems
Reconstruct an ancient ecosystem using multiple independent lines of evidence: isotope analysis of teeth to infer diet and migration, bone histology (growth rings) to estimate age and growth rate, coprolite chemistry for diet, and palaeobotany for habitat — understanding that palaeontology is an evidence-synthesis discipline
Typical age: 12–14 years
“If your child was asked how scientists know a large dinosaur migrated hundreds of kilometres every year, could they explain what kind of evidence they look for and how they rule out alternative explanations?”
