Unveiling Extraordinary Fossils: Shedding Light on the End of the Dinosaur Age

Scientists have uncovered an extraordinary fossil site in Argentina called the Cañadón Tomás Quarry, which is shedding new light on life at the end of the Cretaceous period. The site has revealed numerous bones from hadrosaurs, including individuals of different sizes, potentially indicating a social group or herd. Additionally, the team discovered fossils of non-avian predatory dinosaurs, a Cretaceous snake, and the upper jaw of a small mammal, which is the first of its kind found in the region. The findings provide crucial insights into Southern Hemisphere non-avian dinosaurs and the expansion of mammals following the extinction of dinosaurs. Excavations at the site are ongoing, with the potential for more discoveries and new species.
