- 			 Paleontology PaleontologyGoing Under Down Under: Early people at fault in Australian extinctionsA lengthy, newly compiled fossil record of Australian mammals bolsters the notion that humanity's arrival on the island continent led to the extinction of many large creatures there. By Sid Perkins
- 			 Paleontology PaleontologyOf penguins’ range and climate changeVariations in the range of Adélie penguins along one section of Antarctica's coast during the past 45,000 years are a keen indicator of climate change there. By Sid Perkins
- 			 Paleontology PaleontologyPaleotrickery: A lengthy lineage for leaf-mimicking insectsSpecies in one group of insects have escaped the hungry eye of predators by looking like foliage and moving like swaying leaves for at least 47 million years, a new fossil find suggests. By Sid Perkins
- 			 Paleontology PaleontologyMammals started flying when birds didThe first gliding mammal winged through forests at least 70 million years earlier than scientists had previously presumed, a new fossil shows. The specimen dates from about 150 million years ago, during the time when birds were developing flight. ANCIENT GLIDER. Volaticotherium antiquus was gliding through ancient forests 150 million years ago. The creature weighed […]
