It's several feet shorter, roamed Europe instead of Africa, and sports four horns on its head instead of two. As The New York Times reports, the discovery, outlined in a recent study in the journal PLOS One, sheds new light on the evolutionary history of the long-necked mammals.

The fossil belongs to a newly discovered species of extinct giraffe dubbed Decennatherium rex. It was excavated near Madrid, Spain along with the remains of three other specimens of the same animal, but the other fossils don't compare to the near-complete condition of the first. The creatures lived in the area 9 million years ago, moving the timeline of giraffids' presence in Europe further back than experts previously thought.

NASA has found another 20 promising planets for humans to colonize

  NASA has found another 20 promising planets for humans to colonize An international team of scientists has found 20 more exoplanets that might sustain human life.  The space telescope, Kepler, was launched in 2009 with the specific mission to find extrasolar planets. And scientists have used its data to confirm thousands of them. Kepler broke in 2013, but the area of space it recorded over the four years it was operational contained over 150,000 stars, so there’s still a lot of data to go through.

The ancient species stood 9 feet tall, making it shorter than today's giraffes. While D. rex lacked the modern giraffe's distinctive towering neck, paleontologists were able to classify it as a member of the same family by looking for its double-lobed canine teeth and the bony protrusions on its head called ossicones. Giraffes and okapis are the only remaining members of their family (though the giraffes we think of as one species may actually consist of four), and they both have one set of two ossicones that rise straight from the top of the skull.

In addition to the two small horns at the front of its head, D. rex also appears to have had a second set. This feature differed in females and males: In the female D. rex, ossicones grew to be about 2 inches, while in males their second set could reach up to 16 inches. Though they varied in size, the fact that ossicones appeared in both sexes suggests that they didn't just evolve as a way for males to compete for mates.

First luxury Perigord truffle is cultivated in Britain

  First luxury Perigord truffle is cultivated in Britain A black Perigord truffle has been cultivated in Britain for the first time, and the scientists who announced the breakthrough on Monday said climate change could make it a new British crop. The 16-gramme (0.6-ounce) specimen was cultivated in Wales in the roots of a Mediterranean oak tree that had been treated with truffle spores.Scientists from Cambridge University and Mycorrhizal Systems Ltd (MSL) said they also added lime minerals in the surrounding soil to make it less acidic.A Perigord truffle can be worth as much as £1,700 ($2,200, 1,900 euros) per kilogramme in Britain.

Unlike the modern giraffes , their ancestor had four horns , but he did not have a long neck. The two horns were long to 40 cm long and resembled a Turkish sword. The other two were skin-covered bone bumps at a height of about 5 cm.

The details of giraffe evolution, like how the species developed its elongated neck, are mysteries scientists are just starting to unravel. This most recent discovery adds another important link in the long history of the Giraffidae family.

When distant black holes (or neutron stars) collide, there's a lot scientists can tell from the way they send gravitational waves rippling through space. When distant black holes (or neutron stars) collide, there's a lot scientists can tell from the way they send gravitational waves rippling through space. That includes their masses, their distance, and how their spins line up with one another.
