Overview: This introductory page provides a comprehensive overview of the Jurassic Period, setting the stage for the detailed explorations in the subsequent pages. It covers the major geological shifts, climate changes, and the overarching dominance of dinosaurs during this era.
Eon XXXIIIa – The Rise of the Giants (Early Jurassic)
- Time Frame: 201.3 – 174.1 million years ago
- Highlights:
- Recovery from the Triassic–Jurassic extinction event
- Emergence of early dinosaurs like Dracoraptor hanigani
- Diversification of marine reptiles such as ichthyosaurs and plesiosaurs
- Initial breakup of the supercontinent Pangaea
- Appearance of the first true crocodiles and early mammalsnatmus.
Eon XXXIIIb – The Reptilian Renaissance (Middle Jurassic)
- Time Frame: 174.1 – 163.5 million years ago
- Highlights:
- Proliferation of large sauropods like Brachiosaurus and Diplodocus
- Dominance of theropods such as Allosaurus
- Expansion of conifer forests and fern prairies
- Continued fragmentation of Pangaea leading to the formation of shallow inland seas
- Evolution of early avian species from small theropods
Eon XXXIIIc – The Apex of the Dinosaurs (Late Jurassic)
- Time Frame: 163.5 – 145 million years ago
- Highlights:
- Peak diversity and dominance of dinosaurs
- Appearance of the first birds like Archaeopteryx
- Flourishing of marine life including ammonites and marine crocodiles
- Further continental drift leading to more distinct landmasses
- Development of more complex ecosystems with diverse flora and fauna
