of prehistoric predators. The discovery is centered on the Duwi Formation, a geological layer dating back to the Late Cretaceous period that spans vast sections of Egypt. Researchers have long identified this area as a potential window into the past, as...

Mysterious stone markings reveal a hidden chapter of Earth’s past, offering unexpected fossil evidence that reshapes our understanding of ancient life. Researchers have identified enigmatic depressions and linear marks in ancient Italian sedimentary...

parent species remains a central challenge. Early hypotheses focused on Bonapartenykus, a small theropod known from the Late Cretaceous of the same region, but comparative analysis of shell microstructure dismissed that match. The ornamentation on the...

reshaping scientists’ view of the region’s past. New fossil teeth from Alaska’s Prince Creek Formation show that the Late Cretaceous Arctic was far from barren, supporting a small but diverse group of mammals around 73 million years ago. The finds,...

Dinevenator robustus compared with related troodontid dinosaurs. Credit: Fossil Studies The find broadens our view of Late Cretaceous troodontid diversity, showing that while many members were modest in size, some, like Dinevenator, attained...

Paleontologists have unearthed a 70-million-year-old dinosaur in Patagonia, revealing startling new secrets about one of the most mysterious fossil families. Paleontologists working in the rugged terrain of Patagonia have unearthed a rare window into...

90-million-year-old fossil discovered in Fukushima, Japan, reveals that diverse iguanodontian dinosaurs once thrived in Late Cretaceous coastal ecosystems. A fossilized bone unearthed in 1999 and left largely unexamined for over two decades has provided...

Prefecture. It originated in the Obisagawa Member of the Ashizawa Formation, a geological layer dating back to the Late Cretaceous, approximately 90 to 88 million years ago. According to research published in Paleontological Research, this site was once...

A 7,000‑lb fossil dubbed “Medusa” may hold intact skin and soft tissue beneath its sandstone shell, offering rare insight into ancient life. A coalition of geoscientists and Winona State University alumni unearthed a 66‑million‑year‑old Edmontosaurus...

in the known fossil record, surpassed only by those of the extinct elephant bird. The artifact, which dates back to the Late Cretaceous period, was discovered in coastal sediments that once formed the edge of a temperate Antarctic landscape. Unlike the...

predator appears to have been an inhabitant of freshwater lake ecosystems during the Santonian age of the Late Cretaceous, approximately 84 million years ago. The findings, detailed in the Peer Community Journal, shed light on a niche group of early...

evolutionary narrative, noting that these marine reptiles emerged in the Early Triassic and persisted until the early Late Cretaceous. The group achieved peak diversity and morphological disparity during the first 8.7 million years of its history, a...

History Insights into a Lost Antarctic Landscape The bone dates to roughly 82 million years ago, placing it in the Late Cretaceous when Antarctica was draped in temperate forests that could sustain large herbivores. Although additional dinosaur remains...
