Rib of Scotty the T. rex reveals 66-million-year-old healing wound via neutron imaging

Neutron imaging at Oak Ridge National Laboratory uncovered a vast network of mineralized blood vessels in the healing rib of Scotty, the largest Tyrannosaurus rex. The 66‑million‑year‑old wound began forming new vessels as it healed, and the salty marsh environment helped preserve these soft tissues until Scotty died. Researchers will extend the work to more fossils using neutron and X‑ray imaging to compare healing patterns across species.

Tiny Permian Reptile Sheds Light on the Dawn of Rib-Driven Breathing

Researchers studying a 289-million-year-old Captorhinus aguti fossil from Oklahoma, using neutron tomography, preserved skin, cartilage and protein remnants to reconstruct a rib-based (costal) breathing system—the ancestral mechanism for drawing air into lungs in amniotes—explaining how early land-dwellers became more active; the find also yields the oldest preserved proteins, pushing soft-tissue preservation back about 100 million years, with the fossils housed at the Royal Ontario Museum.

Soft-tissue Archaeopteryx hints at how birds learned to fly

A well-preserved Chicago Archaeopteryx fossil from the Field Museum, examined with CT scans and UV light, reveals preserved soft tissues and long tertial feathers, offering new details on its anatomy and flight capabilities. The findings suggest Archaeopteryx could fly and support the idea that dinosaur flight evolved more than once, reinforcing Darwin’s theory of evolution.

Ancient Plesiosaur Skin Reveals Smooth Tail and Scaly Flippers

A 183-million-year-old plesiosaur fossil (MH7) preserved skin showing a smooth tail and small scales along the rear edges of the flippers, offering rare soft-tissue insights that help reconstruct these sea predators and infer swimming adaptations; soft-tissue preservation is exceptionally rare, with only a handful of plesiosaurs known to have such specimens.

China’s 512-Million-Year-Old Fossil Bed Rewrites Early Cambrian Life

Paleontologists in southern China uncovered the Huayuan biota, a 512‑million‑year‑old fossil bed that preserves soft tissues and documents a richly diverse early Cambrian ecosystem following the Sinsk extinction, with over 50,000 fossils across 153 species—many new to science—revealing complex food webs and evidence of rapid ecological recovery and long‑distance biogeographic links.

Ancient Fossil Discovered in Grand Canyon Reveals 500 Million Years of Prehistoric Life

Scientists discovered exceptionally preserved soft-bodied fossils in the Grand Canyon's Bright Angel Formation, revealing a diverse and complex Cambrian ecosystem that thrived in oxygen-rich shallow waters, challenging previous assumptions about fossil preservation conditions and offering new insights into early animal evolution.

"Revealing the Remarkable Preservation of Ancient Human Brains"

A new study led by researchers at the University of Oxford challenges the belief that brain preservation in the archaeological record is extremely rare. The team compiled a new archive of preserved human brains, revealing that nervous tissues persist in much greater abundances than previously thought, with over 4,000 preserved human brains from over two hundred sources across six continents. The study sheds light on the environmental conditions and mechanisms that contribute to brain preservation, offering unique insights into ancient health, disease, and the evolution of human cognition and behavior.

"Renowned Fossil Revealed as Painted Rock in Paleontological Analysis"

A renowned 280-million-year-old fossil, Tridentinosaurus antiquus, discovered in the Italian Alps in 1931 and thought to show preserved soft tissues, has been revealed to be partly a forgery, with its body outline being painted. New research led by Dr. Valentina Rossi of University College Cork, Ireland, shows that the fossil's celebrated soft tissues are mostly black paint on a carved lizard-shaped rock surface, cautioning against its use in future studies. However, genuine bones and tiny bony scales have been identified, demonstrating how modern analytical paleontology can resolve long-standing enigmas.

"Breakthrough: Australian Chicken Farmer's Fossil Mystery Finally Unraveled"

Scientists have identified a 240 million-year-old fossil discovered by an Australian chicken farmer as a stout amphibian resembling a cross between a crocodile and a giant salamander. The creature, named "Arenaerpeton supinatus," measured 1.2 meters in length and likely preyed on freshwater fish using its gnarly teeth and fang-like tusks. The fossil, which represents a key part of Australia's fossil heritage, has puzzled scientists for almost 30 years and was recently identified through X-ray scanning and analysis.
