Palaeoart & Speculation

Science · Dinosaurs & Paleontology · conceptual

Understand that palaeoart — scientific illustrations and models of dinosaurs — is based on fossil evidence but involves informed speculation about skin colour, feathers, and soft tissues that don't usually fossilise

Sign in to track this

What mastery looks like

  • Explain that bones and teeth are known from fossils but skin colour and soft tissues usually are not
  • State that recent discoveries of preserved skin impressions and feather fossils have improved reconstructions
  • Give an example of how our picture of a dinosaur has changed over time (e.g. feathered vs scaly Velociraptor)

Check your understanding

Does Palaeoart & Speculation understand that pictures of dinosaurs are educated guesses? Can they explain what parts are based on evidence and what parts scientists have to imagine?
