History
Evidence from a Triassic cynodont fossil discovered in Argentina suggests that live birth may have emerged in the mammalian lineage approximately 90 million years earlier than previously thought. Microscopic analysis of the animal's limb bones reveals a 'neonatal line' typically associated with the metabolic stress of birth in placental mammals.
History
A century-old fossil acquired from an Isle of Wight collector has been identified as *Invictibellatrix amberina*, marking the first record of a megaraptoran dinosaur found in Europe. Scans of the small braincase reveal that the four-meter-long predator roamed the Cretaceous landscape long before its massive relatives dominated the Southern Hemisphere.
History
A 5.4-centimeter wooden figurine found on Baffin Island has long been identified as a medieval Norse traveler, but new radiocarbon dating of associated textiles suggests it may represent a later European arrival. Recent analysis of fabric from the same site dates the archaeological layer to the 15th or 16th centuries, coinciding with the voyages of Martin Frobisher rather than the Viking era.
