Scientists are getting closer to unraveling the origins of the first dinosaurs, with evidence pointing to isolated and hard-to-reach regions they may have inhabited for around 230 million years, particularly in Gondwana, a region associated with Pangaea, according to research from University College London and the UK Museum of Natural History.
You need to understand the summary of what you need to do.
- Dinosaurs first appeared more than 230 million years ago in Gondwana, as evidenced by ancient fossils.
- Fossilization is challenging in tropical conditions, making it hard to discover new evidence.
- Researchers propose that significant findings may be concealed in areas like the Sahara and the Amazon.
Where did the dinosaurs originate from, ultimately?
Dinosaurs were spreading worldwide in ancient times, with a strong focus on Gondwana, which includes Africa, South America, South Asia, Australia, and Antarctica. Other continents like Laurasia also indicate dinosaur presence, albeit with less conclusive proof.
Fossil scarcity in equatorial regions like the Sahara and the Amazon is due to the challenging conditions required for fossilization, such as quick burial in sediments. These areas are often inaccessible for paleontological research due to geographic obstacles, political unrest, or financial constraints.
What is indicated by evolutionary research?
Models relying on fossil records and ancient planetary geography propose that Gondwana served as the origin of dinosaurs. Fossils of reptiles like silesaurids, believed to be potential ancestors of dinosaurs in the ornithischian group, support this theory. Finding these creatures in regions now making up the Sahara and the Amazon could be crucial for revealing additional aspects of this narrative.
The potential for future discoveries in untapped areas is bright, despite the obstacles. Science is focused on these locations where new fossils could revolutionize our understanding of dinosaur origins on Earth.
