Scientists have unearthed what could be the world’s oldest ice core

Researchers in Antarctica’s Ong Valley extracted what could be the oldest ice core ever recovered, during the 2017–18 field season.Credit: Jaakko Putkonen Ice in places such as Antarctica acts like a time capsule: its ancient, trapped air bubbles provide snapshots of Earth’s atmosphere from millennia ago. Scientists have been hunting for increasingly older ice to … Read more

Octopus lures from the Mariana Islands found to be oldest in the world

An archaeological study has determined that cowrie-shell artifacts found throughout the Mariana Islands were lures used for hunting octopuses and that the devices, similar versions of which have been found on islands across the Pacific, are the oldest known artifacts of their kind in the world . An archaeological study has determined that cowrie-shell artifacts … Read more

Oldest European salamander fossil, discovered in Scotland, informs amphibian origins

Credit: University College London Fossils discovered in Scotland represent some of the world’s oldest salamanders, according to a new study led by UCL researchers. The research team analyzed 166-million-year-old fossils of a type of animal called Marmorerpeton, found in Middle Jurassic rocks on the Isle of Skye. They found that it has several key salamander … Read more

Earth’s oldest known wildfires raged 430 million years ago

Bits of charcoal entombed in ancient rocks unearthed in Wales and Poland push back the earliest evidence for wildfires to around 430 million years ago. Besides breaking the previous record by about 10 million years, the finds help pin down how much oxygen was in Earth’s atmosphere at the time. The ancient atmosphere must have … Read more

Hot-Blooded or Cold-Blooded? Chemical Clues Solve One of the Oldest Mysteries in Paleontology

Schematic drawing of a subset of the animals that were investigated as part of the research. Metabolic rates and resulting thermophysiological strategies are color-coded, orange hues characterize high metabolic rates coinciding with warm-bloodedness, and blue hues characterize low-metabolic rates coinciding with cold-bloodedness. From left to right: Plesiosaurus, Stegosaurus, Diplodocus, Allosaurus, Calypte (modern hummingbird). Credit: © … Read more
