A newly found species small enough to fit in the palm of a hand is North America’s oldest known primate, according to a new study.

Christopher Beard, a paleontologist at the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania, recently discovered fossils of the 55-million-year-old creature on the Gulf Coastal Plain of Mississippi.

Ancient Global Warming Gave Bugs the Munchies

A temperature spike about 55 million years ago gave bugs the munchies, according to a new study.

If modern temperatures continue to rise as anticipated in the coming years, researchers add, the planet could see a similar increase in insect damage to crops and other plants.

Ancient Warming Caused Huge Spike in Temps, Study Says

What started out as a moderate global warm-up about 55 million years ago triggered a massive injection of greenhouse gases into the atmosphere that sent temperatures skyrocketing, a new study says.

The finding suggests that today’s temperature rise may just be priming the planet for a carbon belch of epic proportions.

Volcanic Activity Triggered Deadly Prehistoric Warming

The prehistoric bout of volcanic activity that slowly ripped Greenland from Europe triggered a deadly global warming event, a new study says.

The event, which happened about 55 million years ago, has similarities to today’s climate changes, which have been linked to human generation of greenhouse gases from fossil fuels.
