China is providing paleontologists with a clearer window into the evolutionary history of vertebrates. The fossilized remains of Asioaspis brachyotus, which dates back approximately 419 million years to the Early Devonian, offer a missing link in...

Still Holds Vast Unknown Biodiversity Oceans conceal more than 70 percent of the planet’s surface, yet the deep‑sea floor remains largely uncharted. Each foray into the abyssal plain carries the potential to reveal organisms never before documented,...

Cycle Still Producing Notable Space Weather Although the Sun has moved past the peak of its current 11‑year cycle, activity remains high enough to generate significant geomagnetic storms. Researchers are watching the orientation of the interplanetary...

emphasized that the results add to mounting evidence that microorganisms played a pivotal role in the survival of ancient remains. The authors propose that this mechanism may represent a global Lagerstätten process, describing the special circumstances...
