A 265-million-year-old fossil discovery in Brazil yields the oldest and largest known predator in South America, predating the rise of dinosaurs. The exquisitely preserved Pampaphoneus biccai had a skull over 40cm long and sharp canine teeth adapted for capturing prey.
A team of researchers from South Africa has discovered exceptional trace fossils that provide insight into the locomotion of ancient giant amphibians. The fossils, found on a rock surface once part of a tidal flat or lagoon, suggest these animals propelled themselves through water with continuous side-to-side tail motions.
A new study reconstructs the skeletal structure of Coelurosauravus elivensis, a Late Permian reptile that likely used tree canopy changes to facilitate its evolution. The research reveals the gliding apparatus was supported by either the gastralia or musculature of the trunk.
A study published in Scientific Reports uses fossilized mollusk shells to investigate ocean chemistry during the end-Permian mass extinction. The analysis found no signs of severe ocean acidification, contradicting previous theories.
Researchers shed light on the evolution of mammalian tusks by tracing them back to ancient mammal relatives called dicynodonts. Dicynodonts had protruding tusks in their upper jaws, but they were not always true tusks – instead, some had enamel-coated teeth that did not fit the definition.
Researchers found that sulfur dioxide and carbon dioxide releases from Siberian volcanoes could have created acidic rain, damaging plants and organisms. The study suggests that ozone depletion and temperature increases contributed to the end-Permian mass extinction on land.
