Fossilized eggshells from the Cedar Mountain Formation in Utah reveal a diverse array of dinosaur species, including multiple types of oviraptorosaurs and other reptiles, sharing nesting sites 100 million years ago, indicating complex ecosystems and migration patterns between Asia and North America.
A new dinosaur fossil named Iani smithi has been discovered in Utah, belonging to a little-known group of herbivorous dinosaurs called rhabdodontomorphs. The Cedar Mountain Formation in Utah near Emery County has provided valuable insights into over 40 million years of dinosaur evolution in North America. Iani smithi joins other herbivorous dinosaur species, indicating a diverse and coexisting ecosystem. This discovery highlights the diversity of dinosaur evolution during the Cretaceous era, underscoring the ongoing quest to uncover more herbivorous dinosaur species.
A geological study of the rock formation that encased a fossilized example of the world's biggest "raptor" dinosaur, Utahraptor, shows it's 10 million years older than previously understood, indicating that the rocks at the Stikes Quarry are at least 135 million years old. The revised age has important implications for the evolutionary history of dinosaurs and narrows the gap in the rock record at the boundary between the Jurassic and Cretaceous Periods in Utah. The study also revealed that the rock strata from the Stikes Dinosaur Quarry were deposited during a global change episode known as the Weissert Event.
