Phanerozoic Eon: The Age of Visible Life ( 541 Mya - Present)

The EON of Visible Life chronicles the transformation of Earth from barren landscapes to oceans teeming with life, and eventually to the first forests, mountains, and river valleys. During this Phanerozoic Eon, continents drifted across the globe, India separated from Gondwana, and Telangana’s landscapes began taking recognizable shape. Fossils of dinosaurs, ancient trees, and other early life forms, discovered in districts like Adilabad, Mulugu, and Khammam, provide glimpses into the rich prehistoric heritage of the region, setting the stage for mammals, humans, and civilizations to come."

🐚 1. Paleozoic Era (541–245 Mya) - Age of Marine life

Global: Marine life flourished; first land plants, insects, amphibians emerged.
India: Part of Gondwana; fossils of trilobites and brachiopods in central and northern India.
Telangana: Stable plateau; erosion and sedimentation shaped early basins.

🦖 2. Mesozoic Era (245–66 Mya) - Age of Reptiles

 Triassic Age (245–208 Mya)

Pangea intact; Telangana a low-lying basin with rivers and lakes

Jurassic Age (208–146 Mya)

Pangea began rifting.
Gondwana: India, Africa, South America, Antarctica, Australia.
Telangana fossils:
Kotasaurus yamanpalliensis (Adilabad)
Petrified trees (Mulugu & Khammam)

Cretaceous Age (146–66 Mya)

Gondwana further broke up; India separated from Africa (~135 Mya) and Madagascar (~90 Mya).
India drifted north rapidly (~15–20 cm/year) toward Asia.
Telangana: Deccan Traps volcanism, fertile black soils; dinosaur extinction.

🐘 3. Cenozoic Era (66 Mya – Present) - Age of Mammals

Age of Mammals and Humans
