Page: https://lightmysky.com/learn/science/areas/dinosaurs-and-paleontology - [Dinosaurs Were Real](https://lightmysky.com/learn/science/dinosaurs-were-real-mt_dpM1l5IOk6): Understand that dinosaurs are real animals. T. rex lived long ago and is extinct, while birds are dinosaurs alive today. - [Famous Dinosaur Species](https://lightmysky.com/learn/science/famous-dinosaur-species-mt_BnabTHkNIp): Recognise and name common well-known dinosaur species: Tyrannosaurus rex, Triceratops, Stegosaurus, and Brachiosaurus/Diplodocus, describing a basic feature of each - [Dinosaur Sizes](https://lightmysky.com/learn/science/dinosaur-sizes-mt_u0TeRwRII_): Compare dinosaur sizes to familiar things — some dinosaurs were as tall as a house, others were as small as a chicken — and understand that dinosaurs came in a huge range of sizes - [Fossils & Palaeontologists](https://lightmysky.com/learn/science/fossils-and-palaeontologists-mt_bKlnc7dyVK): Understand that fossils are the remains of ancient living things preserved in rock, and that scientists called palaeontologists study fossils to learn about dinosaurs - [Plant-Eaters vs Meat-Eaters](https://lightmysky.com/learn/science/plant-eaters-vs-meat-eaters-mt_DJh2JPwTf6): Sort dinosaurs into plant-eaters (herbivores) and meat-eaters (carnivores) by looking at clues like tooth shape — flat teeth for plants, sharp teeth for meat - [Real Dinosaurs vs Fiction](https://lightmysky.com/learn/science/real-dinosaurs-vs-fiction-mt_JednrdYqpt): Distinguish real dinosaurs from fictional or commonly confused creatures — pterosaurs (flying reptiles) and plesiosaurs (marine reptiles) were not dinosaurs, and movie dinosaurs are not always accurate - [Fossils Reveal Ancient Environments](https://lightmysky.com/learn/science/fossils-reveal-ancient-environments-mt_fKwgN61ttR): Understand that fossils tell us not only about ancient animals but also about ancient environments — for example, marine fossils found on a mountaintop show that area was once underwater - [Mary Anning, Fossil Hunter](https://lightmysky.com/learn/science/mary-anning-fossil-hunter-mt_excSPNHJWZ): Know who Mary Anning was — a pioneering fossil hunter from Lyme Regis, England, who discovered ichthyosaur and plesiosaur skeletons in the early 1800s and contributed to our understanding of prehistoric life - [The Mesozoic Era](https://lightmysky.com/learn/science/the-mesozoic-era-mt_uQljqc0J5j): Place the three periods of the Mesozoic Era — Triassic, Jurassic, and Cretaceous — in order and understand that different dinosaurs lived in different periods, not all at the same time - [Dinosaurs Around the World](https://lightmysky.com/learn/science/dinosaurs-around-the-world-mt_oH1XC8aQYn): Understand that different dinosaurs lived on different continents and that fossil discoveries around the world show dinosaurs were a global phenomenon, with some species found only in certain regions - [Dinosaur Hip Groups](https://lightmysky.com/learn/science/dinosaur-hip-groups-mt_yrSdVrXrsF): Classify dinosaurs into the two major groups based on hip structure: Saurischia (lizard-hipped, including theropods and sauropods) and Ornithischia (bird-hipped, including Triceratops and Stegosaurus) - [The K-Pg Extinction Event](https://lightmysky.com/learn/science/the-k-pg-extinction-event-mt_QHKqckBdAk): Describe the Cretaceous–Palaeogene (K-Pg) extinction event approximately 66 million years ago, including the asteroid impact theory and its evidence (iridium layer, Chicxulub crater), and understand that this ended the reign of non-avian dinosaurs - [Fossilisation: Why Sediment, Minerals and Luck All Matter](https://lightmysky.com/learn/science/fossilisation-why-sediment-minerals-and-luck-all-matter-mt_iycQEai3dK): Explain in simple terms how fossils form: an organism dies and is quickly buried in sediment; over millions of years minerals replace the remains and the sediment turns to rock, preserving the shape - [Types of Fossils](https://lightmysky.com/learn/science/types-of-fossils-mt_1VSFoM44JU): Distinguish body fossils (preserved bones, teeth, shells) from trace fossils (footprints, trackways, eggs, burrows, coprolites) and explain what each type can tell scientists - [Fossilised Dinosaur Dung](https://lightmysky.com/learn/science/fossilised-dinosaur-dung-mt_1dXhJp6qLJ): Describe what coprolites are (fossilised dinosaur dung) and how palaeontologists analyse them to discover what dinosaurs ate, including plant fragments, bones, and seeds - [Reading Dinosaur Trackways](https://lightmysky.com/learn/science/reading-dinosaur-trackways-mt_Wpvuz3mvBq): Use dinosaur trackways (fossilised footprints) to make inferences about a dinosaur's size, speed, and behaviour — widely spaced prints suggest running, closely spaced suggest walking - [How Palaeontologists Work](https://lightmysky.com/learn/science/how-palaeontologists-work-mt_JBWMqZVO7S): Describe how palaeontologists work in the field and lab: prospecting for exposed fossils, careful excavation with hand tools, plaster jacketing for transport, preparation in the lab, and scientific description and publication - [Rock Layers & Relative Dating](https://lightmysky.com/learn/science/rock-layers-and-relative-dating-mt_EGIlsfHxb6): Understand that rock layers (strata) form in sequence with the oldest at the bottom and the youngest at the top, and that fossils found in deeper layers are older — this is the principle of relative dating - [Radiometric Dating](https://lightmysky.com/learn/science/radiometric-dating-mt_bHbpLW1HUg): Explain how radiometric dating works — radioactive isotopes decay at a known rate (half-life), so measuring the ratio of parent to daughter isotope in a rock or fossil gives an absolute age; distinguish between carbon-14 (useful up to ~50,000 years) and uranium-lead (useful for millions to billions of years) - [Fossils as Evidence](https://lightmysky.com/learn/science/fossils-as-evidence-mt_6Z42wJaKYG): Analyse and interpret data from fossils to provide evidence of organisms and environments that existed long ago - [Life Changed Over Time](https://lightmysky.com/learn/science/life-changed-over-time-mt_gTDqxYkLs9): Recognise that living things have changed over time and that fossils provide information about organisms that inhabited the Earth millions of years ago - [Birds Evolved from Dinosaurs](https://lightmysky.com/learn/science/birds-evolved-from-dinosaurs-mt_T8JGTJ-oNI): Understand that modern birds evolved from a group of small feathered theropod dinosaurs, using evidence such as the fossil Archaeopteryx, feathered dinosaur fossils from China, and shared skeletal features - [Palaeoart & Speculation](https://lightmysky.com/learn/science/palaeoart-and-speculation-mt_M8UQTURODF): 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 - [Dinosaur-to-Bird Transition](https://lightmysky.com/learn/science/dinosaur-to-bird-transition-mt_mqQ-DtH5m-): Trace the evidence for the dinosaur-to-bird transition in depth: feathered theropods from the Liaoning Formation (China), the mix of dinosaur and bird features in Archaeopteryx, and the competing ground-up versus trees-down hypotheses for the origin of flight - [Mass Extinctions in Earth History](https://lightmysky.com/learn/science/mass-extinctions-in-earth-history-mt_IP0PTVfTXp): Compare the five major mass extinction events in Earth history (End-Ordovician, Late Devonian, End-Permian, End-Triassic, K-Pg), describe proposed kill mechanisms for each (glaciation, oceanic anoxia, volcanic mega-eruptions, asteroid impact), and explain why mass extinctions, while catastrophic, also open ecological space for subsequent evolutionary radiations - [Megafauna Extinction & De-Extinction](https://lightmysky.com/learn/science/megafauna-extinction-and-de-extinction-mt_tGZ2sMzMGz): Evaluate the debate over what drove Pleistocene megafauna to extinction — human overkill, climate change, or a combination — using evidence from fossil records, ancient DNA, and archaeological sites; connect to the present-day sixth mass extinction and consider the ethics and feasibility of de-extinction using ancient DNA - [Reading Cladograms](https://lightmysky.com/learn/science/reading-cladograms-mt_cSPtyLF3q1): Read and create simple cladograms (branching diagrams) that show how groups of dinosaurs are related based on shared features, understanding that species sharing more features are more closely related - [Changing Scientific Knowledge](https://lightmysky.com/learn/science/changing-scientific-knowledge-mt_0T0Zf0YG6k): Evaluate competing scientific explanations about dinosaurs by weighing fossil evidence — understanding that scientific knowledge changes as new fossils are discovered and new methods of analysis are developed - [Reconstructing Ancient Ecosystems](https://lightmysky.com/learn/science/reconstructing-ancient-ecosystems-mt_8_BxtNDrLZ): 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
