Fossilized vertebrae, initially misidentified as part of a marine reptile in 1985, were later recognized as belonging to a sauropod dinosaur. The find, made on James Ross Island, highlights the limited number of known dinosaur species in Antarctica—only twelve have been identified so far. Paleontologist Paul Barrett notes that this fossil represents the first confirmed dinosaur remains found in Antarctica, though it is incomplete and cannot yet determine the exact species. The study suggests the creature was likely a juvenile titanosaur, measuring around seven meters in length.

Vědci je našli u tvora starého půl miliardy letThe article discusses a scientific discovery regarding the evolutionary history of spider fangs, revealing that they originated much earlier than previously thought. Researchers identified the origin of these specialized structures in a creature called Urokodia, which lived approximately 518 million years ago—about 200 million years before the first eight-legged arachnids appeared. This finding challenges previous assumptions about the evolution of predatory traits in arthropods. The study, conducted by Chinese and British scientists using advanced imaging techniques, examined exceptionally well-preserved fossils from China. They discovered that Urokodia possessed primitive 'chelicerae'—structures that would later evolve into the fangs of spiders, scorpions, and other arthropods. These findings provide new insights into the early development of complex feeding mechanisms among ancient creatures.
