Recent research has revealed that the small predator previously thought to be a juvenile T. rex is actually a fully grown Nanotyrannus lancensis, rewriting the understanding of dinosaur growth, evolution, and ecosystem dynamics during the Late Cretaceous period, and introducing a new species, Nanotyrannus lethaeus.
Paleontologists discovered 76-million-year-old footprints in Alberta, Canada, providing the first evidence of multispecies herding among dinosaurs, including ceratopsians, ankylosaurs, and tyrannosaurs, suggesting complex social behavior and possible defense strategies against predators.
Researchers have unearthed a treasure trove of 100 million-year-old dinosaur tracks and fossils in Alaska's Nanushuk Formation, shedding light on a diverse Cretaceous ecosystem. The site boasts 75 dinosaur tracks, 2-foot-wide tree stumps, leaves, and feces, offering a glimpse into an ancient landscape. The majority of tracks were left by herbivorous dinosaurs, while some belonged to meat-eating dinosaurs and extinct shorebirds. The findings also revealed that the Arctic region had a warm and wet climate similar to modern-day South Florida, providing valuable insights into the ancient environment.
