Researchers have identified a new prehistoric reptile species, Sonselasuchus cedrus, from a fossil bonebed in Arizona's Petrified Forest National Park. The species, roughly the size of a poodle, belonged to a group of reptiles that resembled dinosaurs and lived during the Late Triassic period. The discovery stems from over a decade of excavation and collaboration between the University of Washington and the National Park Service.
Facts First
- A new reptile species, Sonselasuchus cedrus, has been described from fossils found in Arizona's Petrified Forest National Park.
- The species was roughly the size of a poodle and stood about 25 inches tall.
- It belonged to the shuvosaurid group of reptiles, which lived during the Late Triassic period (225-201 million years ago) and resembled dinosaurs.
- The discovery involved over a decade of excavation by University of Washington researchers and the National Park Service, yielding more than 3,000 fossil bones.
- The study was published in the Journal of Vertebrate Paleontology by researchers from the University of Washington Department of Biology and the Burke Museum.
What Happened
Researchers from the University of Washington Department of Biology and the Burke Museum have described a new prehistoric reptile species named Sonselasuchus cedrus. The species belongs to a group of reptiles known as shuvosaurids, which lived during the Late Triassic period (approximately 225-201 million years ago) and closely resembled ornithomimid dinosaurs. The discovery is based on fossil remains excavated from Petrified Forest National Park in Arizona. The reptile was roughly the size of a poodle and stood about 25 inches tall. Its physical characteristics, based on the fossils, include a likely toothless beak, large eye sockets, and hollow bones.
Why this Matters to You
This discovery adds a new piece to the puzzle of Earth's ancient ecosystems. If you have an interest in natural history or visit national parks like Petrified Forest, this research deepens the scientific story behind the landscapes you see. The ongoing collaboration between universities and the National Park Service demonstrates how public lands serve as vital repositories for understanding our planet's past.
What's Next
The extensive Sonselasuchus bonebed... may continue to provide material for further study. The decade-long excavation and preparation effort, involving over 30 University of Washington students and volunteers, suggests that research at the site is likely to continue. Future studies could provide more details about the species' behavior, ecology, and its place within the Late Triassic environment.
