Pangea & the Age of Dinosaurs: Earth in the Mesozoic Era

The golden age of archosaurs and giant dinosaurs, the breakup of supercontinent Pangaea into Laurasia and Gondwana, radiation of flowering plants (angiosperms), and the Chicxulub asteroid impact.

Geological & Paleobiological Data Integration In Progress

This epoch belongs to Earth’s deep-time evolutionary continuum (252 Ma – 66 Ma). We are actively calibrating tectonic continental drift meshes and paleobiology fossil coordinates for this period.

Currently Active: Full Human History GIS Dataset (3300 BCE – 2026 CE)

Our interactive map engine is currently dedicated to displaying our 12 collected layers across 5,500 years of recorded human civilization—including 13,800+ dated border shapes, 30 ancient wonders, classical archaeology, and trade routes.

Epochal Mechanics & Planetary Evolution

The Mesozoic ("Middle Life") was the dominion of dinosaurs, pterosaurs, and marine reptiles. Across the Triassic, Jurassic, and Cretaceous, tectonic rift zones broke Pangaea apart, opening the Atlantic Ocean and Tethys Seaway. Flowering plants diversified, while early avian dinosaurs evolved feathered flight. The era was brought to an abrupt conclusion 66 million years ago when a 10-kilometer asteroid struck the Yucatán Peninsula.

Key Evolutionary & Geological Milestones:

  • •Evolution and global diversification of Theropoda, Sauropoda, and Ornithischia
  • •Continental drift opening the proto-Atlantic and isolating biogeographic realms
  • •Angiosperm radiation: flowering plants co-evolving with insects (~130 Ma)
  • •Chicxulub K-Pg impact event terminating 75% of terrestrial and marine species
