Gigantic Apes Coexisted With Early Humans

LiveScience:

Scientists have known about Gigantopithecus blackii since the accidental discovery of some of its teeth on sale in a Hong Kong pharmacy about 80 years ago. While the idea of a giant ape piqued the interest of scientists – and bigfoot hunters – around the world, it was unclear how long ago this beast went extinct.

Now Jack Rink, a geochronologist at McMaster University in Ontario, has used a high-precision absolute-dating method to determine that this ape – the largest primate ever – roamed Southeast Asia for nearly a million years before the species died out 100,000 years ago during the Pleistocene period. By this time, humans had existed for a million years.

Indonesian Crow Rediscovered

LiveScience:

The all-black Banggai Crow (Corvus unicolor), known to science only by two specimens described in 1900, was found again by Indonesian biologists on Peleng Island, off the east coast of Sulawesi, Indonesia, in 2007. Pamela Rasmussen, a Michigan State University zoologist verified the finding.

An Interglacial Jump In Sea Level

Nature:

The potential for future rapid sea-level rise is perhaps the greatest threat from global warming. But the question of whether recent ice loss from Greenland and Antarctica is the first indication of such a rise is difficult to answer given the limited duration of the instrumental record. New evidence from an exceptionally exposed fossil reef in the Xcaret theme park in Mexico provides a detailed picture of the development of reef terraces, erosion surfaces and sea-level excursions in the region during the last interglacial. A combination of precise uranium-series dating and stratigraphic analysis, together with comparison with coral ages elsewhere, suggests that a sea-level jump of 2 to 3 metres occurred about 121,000 years ago, consistent with an episode of ice-sheet instability towards the end of the last interglacial. On that evidence, sustained rapid ice loss and sea-level rise in the near future are possible.

Paleontologists Strike Fossil Gold In Colombia

Washington Post:

Last month, an international group of scientists revealed in the journal Nature that Jaramillo’s team had made a startling discovery — a species of snake larger than a school bus that ruled northern South America 60 million years ago. Evolving after the extinction of the dinosaurs, Titanoboa cerrejonensis — or titanic boa from Cerrejon — might have been the largest vertebrate living on land at that time, the Paleocene era.
