Researchers analyzing a remarkably preserved Edmontosaurus sacrum detected remnants of endogenous collagen and related amino acids in a 66-million-year-old fossil, providing strong evidence against the idea that original biomolecules are always destroyed over deep time and potentially enabling new insights into dinosaur evolution and biology.
Paleontologists describe a nearly complete Edmontosaurus skull with a Tyrannosaurus tooth embedded in its snout and bite marks suggesting a fatal, close-range encounter. CT analysis indicates the tooth broke off during the attack, with the Edmontosaurus unlikely to survive; size estimates point to an adult T. rex with about a 1-meter-long skull. The find provides rare direct fossil evidence of predation and feeding behavior in large theropods, showing T. rex likely hunted and scavenged during its life.
Researchers from the University of Chicago discovered remarkably detailed dinosaur mummies of Edmontosaurus, preserved through a process called clay templating that captured soft tissues, skin, and even hooves, providing unprecedented insights into the dinosaur's appearance and anatomy.
Scientists have discovered a 'mummy zone' near Lusk, Wyoming, where exceptionally preserved dinosaur fossils, including Edmontosaurus with soft tissue, suggest the potential for finding complete T. rex or Triceratops specimens, offering unprecedented insights into dinosaur appearance and evolution.
Paleontologist Paul Sereno and his team uncovered new details about the appearance of the duck-billed dinosaur Edmontosaurus annectens by studying two specimens, including the only juvenile dinosaur mummy ever found, with the help of historical archives and local ranchers, revealing intricate details of its anatomy and preservation.
Scientists discovered the first complete fossilized mummies of hoofed dinosaurs, specifically juvenile and adult Edmontosaurus specimens in Wyoming, providing unprecedented insights into their biology, movement, and the presence of hooves, which were confirmed through advanced imaging techniques.
Researchers reexamined 100-year-old dinosaur fossils from Wyoming and discovered they are exceptionally well-preserved, retaining skin, spikes, and hooves, providing the most complete view of a large dinosaur to date and offering new insights into their appearance and soft tissue preservation.
Scientists reexamined 100-year-old fossils of Edmontosaurus annectens from Wyoming and discovered exceptionally preserved mummified body parts, including skin, hooves, and spikes, providing new insights into the dinosaur's appearance and biology, such as the first evidence of hooved feet in a reptile and detailed skin features.
Scientists have discovered well-preserved dinosaur mummies from Wyoming that reveal some had hooves, a first in paleontology, providing new insights into dinosaur anatomy and appearance.
Two exceptionally preserved dinosaur mummies from Wyoming reveal that Edmontosaurus, a duckbilled dinosaur from 66 million years ago, had hooves on its feet, marking the first evidence of hooves in dinosaurs, and providing detailed insights into its external anatomy and appearance.
Scientists discovered that 66-million-year-old dinosaur 'mummy' skin was actually a thin layer of clay that formed a perfect mask, preserving detailed features like scales, hooves, and spikes, providing new insights into dinosaur preservation and appearance.
Scientists have discovered exceptionally preserved dinosaur mummies of Edmontosaurus that reveal the first known reptile hooves, providing new insights into dinosaur anatomy and death conditions, with these mummies offering rare soft tissue preservation and details about their last moments.
Two well-preserved mummified Edmontosaurus fossils, discovered in Wyoming in the early 1900s, provide insights into the preservation process of dinosaurs, with one specimen found resting on its rib cage and dating back approximately 66 million years.
