The video discusses the discovery of new Sphenodontian fossils in Argentina, revealing that these ancient reptiles survived longer than previously thought. The fossils, found in Patagonia, are about 90 million years old and provide insights into the survival of their only living relative, the Tootara from New Zealand. The Argentinian paleontologists found that these prehistoric lizards were abundant and belonged to the largest Fenadontian discovered so far. The findings suggest that these creatures survived longer in Gondwana, the ancient supercontinent, compared to northern land masses.
