Scientists name new fossil species after Millennium Falcon from Star Wars



A new species from the Burgess Shale was discovered by paleontologists of the Royal Ontario Museum.

Paleontologists who excavated a site known as Burgess Shale in the Canadian Rockies have discovered the fossil remains of a hitherto unknown arthropod species with a striking horseshoe-shaped upper shell. They named the Cambroraster falcatus after the Millennium Falcon spaceship, which drove Han Solo in the Star Wars franchise. The discovery, published in a recent article in the journal Proceedings of the Royal Society B, sheds light on the diversity of the earliest relatives of insects, crabs and spiders.

909 by palaeontologist Charles Walcott and dated to the middle of the Cambrian region about 508 million years ago, the Burgess Shale has since become one of the richest finds of extant fossils from that period. The late Stephen Jay Gould perpetuated his prominence in his bestselling "Wonderful Life" (19459014), published in 1989, in which he argued (somewhat controversially) that the sheer diversity of Burgess shale fossils was evidence of several unique evolutionary lineages that became extinct were, rather, moving on to today's modern Phyla. The Burgess Shale was declared a World Heritage Site in 1980.

In 2013, scientists discovered another piece of the Burgess Shale in Kootenay National Park and dug up the fossil remains of some 50 new species in just 15 days. In this area, a team of paleontologists from the Royal Ontario Museum discovered this latest arthropod.

As the geologist David Bressan, who was not involved in the discovery, writes in Forbes:

Cambroraster falcatus shows how Anomalocaris lateral lobes spanning the lower part of the body stretched, and a set of disc-like jaws. The new species was smaller than Anomalocaris up to a foot long, but still a giant compared to other Burgess shale creatures, most of them less than an inch long. His body is protected by an unusually large tank that covers almost the entire animal. The researchers believe that Cambroraster was a predator like his larger relative. In contrast to Anomalocaris a fast swimmer who can catch prey in the open water with his tentacles thanks to his flexible side fins, Cambroraster used his Karapax to plow through the upper strata of the seafloor. "We really did not know what to do with it," co-author Joe Moysiuk of the University of Toronto told CBC News. "We called it & # 39; the spaceship & # 39; because we thought it is very similar to the Millennium Falcon ." And the name has been preserved, to the delight of Star Wars fans everywhere.

"Cambroraster shows a kind of mish-mash of features that we see in some modern groups," Moysiuk said about the significance of the fund. "It tells us that the Cambrian ecosystems were really complex, this is not a primitive, simple organism, this is a highly specialized predator."
