Dinosaurs for Adults – Knowledge & Fun
Facts, science, and teaching tips for parents and educators.
Scientific Facts
- Dinosaurs lived for over 165 million years.
- Fossils help us infer diet, movement, and behavior.
- Birds evolved from theropod dinosaurs.
Evolution & Extinction
Most evidence points to a massive asteroid impact plus volcanic activity and climate change at the end of the Cretaceous.
After the event, mammals diversified rapidly in new niches.
Paleontology Today
- CT scans to study bone interiors.
- 3D modeling for posture and gait.
- Isotopes to infer diet and migration.
For Parents & Teachers
- Use timelines to compare Triassic–Jurassic–Cretaceous.
- Explain evidence: fossils, strata, radiometric dating.
- Prompt critical thinking with “How do we know?” questions.
