Researchers recently found fossils of a large, salamander-like creature with sharp teeth that lived in water before dinosaurs. This predator, larger than a human, likely used its broad head and strong teeth to catch prey. The skull, measuring about 60 centimeters long, along with other parts, was carefully studied after its discovery around ten years ago. A recent study published in Nature focused on Gaiasia jennyae, which existed approximately 280 million years ago in what is now Namibia, a region then covered by glaciers. This discovery indicates that tetrapods, ancestors of amphibians, birds, and mammals (including humans), thrived in colder climates earlier than previously believed. Claudia Marsicano, a co-author from the University of Buenos Aires, emphasized the evolutionary significance of tetrapods. The creature’s name, Gaiasia jennyae, honors paleontologist Jennifer Clack for her contributions to early tetrapod research.
