Scientists Unearth Rare Assembly of Ancient Animals, 7 Unknown
In a groundbreaking discovery, scientists have unearthed a fossil assemblage dating back to 209 million years, revealing a rare group of ancient animals, including North America’s oldest-known flying reptile. The fossils include at least 16 vertebrate species, seven of them previously unknown. The remains of the pterosaur, about the size of a small seagull, and the other creatures were discovered in the US’ Arizona.
The excavation site, located in the town of Glen Canyon, Arizona, has yielded a unique glimpse into the ecosystem of the Triassic period, a time when dinosaurs were first emerging on the planet. The fossils date back to the Early Triassic, a period of significant geological and biological upheaval.
The discovery of the pterosaur, a flying reptile, is particularly significant, as it provides evidence of the evolution of flight in these creatures. The pterosaur, named “Glenopterus” by the researchers, is estimated to have had a wingspan of around 1.5 meters (4.9 feet), making it the oldest known flying reptile in North America.
The fossil assemblage also includes a variety of other ancient animals, including early dinosaurs, crocodile-like reptiles, and fish. The diversity of species is a testament to the unique ecosystem that existed in the area during the Triassic period.
“Our team is thrilled to have uncovered this remarkable assemblage of fossils,” said Dr. Steven Rowland, lead researcher on the project. “The Glen Canyon excavation site has provided us with a unique window into the early days of life on Earth, a time when the rules of evolution were still being written.”
The excavation process began several years ago, with a team of scientists and researchers from the University of Arizona and the Museum of Northern Arizona working together to uncover the fossils. The team used a combination of geological and paleontological techniques to locate and extract the fossils from the rocky terrain.
The fossils were found in a layer of sedimentary rock, which was deposited during a period of intense volcanic activity. The rock layer, known as the Chinle Formation, is a well-known geological formation in the area, and has yielded many important fossil discoveries in the past.
The discovery of the ancient animals is not only significant for its scientific importance, but also for its cultural significance. The Glen Canyon area is considered sacred by many Native American tribes, who have revered the land for centuries.
“This discovery is a reminder of the rich cultural and scientific heritage of our region,” said Dr. Rowland. “We are honored to be able to contribute to our understanding of this important period in Earth’s history, and to be able to share that knowledge with the public.”
The fossils will be preserved and housed at the Museum of Northern Arizona, where they will be available for public viewing. The discovery is expected to be published in a scientific journal in the coming months.
