 Origin of Dinosaurs

  • Dinosaurs, including plant-eating giants like Argentinosaurus and meat-eating ones like Tyrannosaurus, once dominated Earth's land ecosystems.

  • The exact origin of dinosaurs is still unclear, especially regarding when and where they first appeared.

  • New research suggests dinosaurs likely originated in the low-latitude regions of the supercontinent Gondwana.

  • This area includes modern-day northern South America (Amazon region) and northern Africa (Sahara desert).

Geological Context

  • During the Triassic Period (around 245-230 million years ago), all continents were part of Pangaea, and dinosaurs emerged in its southern portion, Gondwana.

  • The regions where they likely originated were close to the equator and had hot, dry climates, including deserts, savannahs, and possibly forested areas with seasonal wildfires.

Early Dinosaur Fossils

  • The earliest-known dinosaur fossils date to roughly 230 million years ago, such as Eoraptor, Herrerasaurus, Saturnalia, and Mbiresaurus.

  • These fossils show differences, indicating that dinosaur evolution had already been underway for millions of years.

Challenges & Evolution

  • Fossils from this period are rare due to preservation challenges and the remote, difficult terrain of the Sahara and Amazon.

  • Dinosaurs evolved after the Permian mass extinction, which occurred 252 million years ago due to extreme volcanism.
