New research suggests that the first dinosaurs likely originated in areas like the Congo Basin and Sahara Desert, rather than previously thought locations such as Argentina or Zimbabwe. This finding indicates that dinosaurs were established much earlier and coexisted with other species, evolving over time into the large creatures known today.

Scientific research is shedding light on the origins of dinosaurs, which have fascinated humans for centuries. Recently, an investigation published in the journal Current Biology, led by Joel Heath from University College London, has provided pivotal insights into where the first dinosaurs may have appeared on Earth.

Historically, Argentina and Zimbabwe were regarded as primary sites for dinosaur fossils. However, this new study indicates the beginnings of these ancient creatures might trace back to regions like the Congo Basin, the Sahara Desert, or even the Amazon rainforest.

The study draws on fossil evidence demonstrating that dinosaurs were already established millions of years before the notable finds in known fossil sites. The implications of this research suggest that gaps in discovery do not equate to a lack of species existence in various regions but rather reflect areas needing further exploration.

This novel research posits that the first dinosaurs likely originated in Gondwana and were not dominant species, cohabiting with organisms such as crocodiles. Initially, these dinosaurs were also smaller than their later descendants, with size evolution being a significant factor in their development over time.

In summary, ongoing research is reshaping our understanding of dinosaur origins. New findings suggest that the first dinosaurs may have emerged from regions previously overlooked, such as the Congo Basin and the Sahara, rather than traditional sites in Argentina and Zimbabwe. This challenges previous assumptions and highlights the importance of further fossil exploration.
