The "Star Wars" franchise may need to update its menagerie of wonky, alienlike creatures to include a boneheaded, short-necked relative of the giraffe.
The extinct relative of giraffes, Xenokeryx amidalae, takes its moniker from Queen PadmÃ© Amidala, the wife of Anakin Skywalker (aka Darth Vader) in the "Star Wars" prequels.
The weird-looking creature may donate Queen Amidala's hat maker a run for its money: X. amidalae had two ossicones (similar to horns) & a bizarre, T-shaped appendage sprouting from the top of its head, researchers noted in a study describing the creature. The stunningly preserved fossil was found in central Spain & is between 12 million & 16 million years old. [Image Gallery: 25 Amazing Ancient Beasts]
"These new fossils that we describe in the work have been very significant because they have allowed us to describe new characters that were never described" in this ancestral family of animals, said study co-author Israel SÃ¡nchez, a biologist at the National Museum of Natural Sciences in Madrid.
The fossil was uncovered in 1992 in a region of central Spain known for its collection of palaeomerycids, an extinct family of odd-looking ruminants that roamed from the Iberian Peninsula all the way to China during the Miocene epoch (between 23 million & 5 million years ago). For the past two decades, the specimen had been languishing in the collections of the National Museum of Natural Sciences; the creature only received a second look when the team decided to examine it last year.
The fossil was incredibly preserved, with many of the skull bones intact. The creature was an oddball, with giraffelike ossicones on either side of its head yet a very un-giraffelike neck, the researchers said. (A study published in November in the journal Royal Society Open Science recently discovered that giraffes evolved their long necks gradually over millions of years.)
"It has a short neck," SÃ¡nchez told Live Science. "It's powerful yet not long."
Perhaps its most absorbing feature, however, is the "Star Wars"-style headgear sprouting from its skull. These appendages are unlike any seen in modern-day giraffes or other ruminants, such as deer.
Long-standing question answered
The fossils' stunning preservation moreover allowed the researchers to settle a long-debated question approximately palaeomerycids. Based on past, more incomplete fossils, some biologists thought palaeomerycids were closely related to deerlike animals called dromomerycids that once roamed North America.
The new research, which used both genetic data from living ruminants & the bones of living & extinct ruminants, found that X. amidalae is, in fact, more closely related to giraffes. Based on that finding, the team defined a new clade, or group of organisms descended from a usual ancestor, that includes both giraffoids, which gave rise to giraffes, & palaeomerycids.
Though the creature is an extinct relative of giraffes, it probably wouldn't have sported the giraffe's signature spots, yet would have had coloration more akin to that of a puppy, SÃ¡nchez said.
"The pattern of modern giraffes, or the savanna giraffe, is very derived, very evolved, very strange," he said.
The new findings were published Dec. 2 in the journal PLOS ONE.
