Two groups of researchers have discovered evidence of humans living in Europe more than 40,000 years ago, older than any physical remains found there before.
"They’re essentially the same as us," said Thomas Higham of the University of Oxford, who studied a jawbone that had been found in 1927 near Torquay in the United Kingdom.
As suggested in the "Ice Age" movies, some crazy-looking creatures roamed the planet millions of years ago. But there is a large gap in the fossil record from about 60 million to 120 million years ago when it comes to mammals in South America. Where were they, and what did they look like?
Scientists have now discovered a quirky little creature from this time period, as reported in the journal Nature. It's called Cronopio dentiacutus, and it resembles a mouse-sized squirrel with proportionally long teeth, although technically speaking it is neither a squirrel nor saber-toothed.
