Fossils Practice Tests

Free, AI-generated Fossils practice tests for Science Olympiad. Choose Invitational, Regional, State, or National difficulty, import past exam PDFs, and track your scores over time.

Fossils is not part of the 2027 event lineup - it ran in recent seasons, and retired events like this often return in later years. This guide and its practice tests remain open, and invitationals sometimes choose to run retired events.

What Fossils Tests Cover

fossil types, preservation methods, index fossils, geological time periods, and paleoenvironments. GEOLOGICAL TIME SCALE (oldest to youngest): - Precambrian (4.6 bya - 541 mya): First life, stromatolites, Ediacaran fauna - Paleozoic (541-252 mya): Cambrian explosion, trilobites, first fish, amphibians, reptiles. Ends with largest mass extinction (Permian) - Mesozoic (252-66 mya): Age of dinosaurs. Triassic → Jurassic → Cretaceous. Ends with K-Pg extinction (asteroid) - Cenozoic (66 mya - present): Age of mammals. Paleogene → Neogene → Quaternary INDEX FOSSILS (must be widespread, short-lived, abundant, easily identified): - Trilobites: Paleozoic (especially Cambrian-Ordovician) - Ammonites: Mesozoic - Brachiopods: Throughout Paleozoic

  • Ammonites: Mesozoic
  • Brachiopods: Throughout Paleozoic

Fossil types

  • Body fossils: Actual remains (bones, shells, teeth)
  • Trace fossils: Evidence of activity (footprints, burrows, coprolites)
  • Mold: Cavity left by organism; Cast: Mineral filling of mold COMMON MISTAKES: Mixing up geological eras/periods. Confusing mold vs cast.
