    Cambroraster falcatus was an ancient, primitive arthropod that dominated the ocean approximately 506 million years ago during the Cambrian period. The creature's name was inspired, in part, by Star Wars' Millennium Falcon due to its similar resemblance of the fictional spacecraft (sort of). C. falcatus, which was roughly the size of a human hand when fully grown though this fossil was nearly a foot long, also bore a striking resemblance to the modern horseshoe crab, per a study published in Proceedings of the Royal Society B: Biological Sciences. The anatomy of the apex predator featured a carapace that covered its...

    Northern and Southern California seafood fans say they’re buying giant lobster claws sold at Costco stores, and photos on Instagram and Reddit suggest each claw is much larger than a human hand. Screenshot from Instagram ================================================================= Seafood lovers on Instagram and Reddit are freaking out over photos showing gigantic lobster claws, and those posting the pictures say they bought them at Costco stores. “This thing is unreal!” one Instagram user wrote this week, sharing a couple of photos of a massive claw in Southern California’s Newport Beach. “I mean, come on. I’ve seen a few big claws at Costco...
  • What the heck are these 520-million-year-old blobs? Experts can't agree

    Here's a brainteaser: Do the 520-million-year-old fossils of an ancient, bug-like creature actually show a silhouette of its brains? Or are these blobby shapes in its head merely fossilized bacteria? According to a new study, the fossilized structures in the Cambrian-period creature's head aren't brainy remains, but rather fossilized bacterial mats, called biofilms. However, not everyone is on board with this interpretation. The researchers who originally discovered the brains are standing by their results, and other paleontologists Live Science interviewed agree with them. [Fabulous Fossils: Gallery of Earliest Animal Organs] The creature in question, Fuxianhuia protensa, is an early arthropod,...

    Paleontologists have discovered the fossilized remains of a new arthropod. Yawunik kootenayi was swimming around oceans in Canada in the Cambrian period, 508 million years ago. It's thought to share a common ancestor with today's spiders and scorpions. The arthropod had four eyes and arms lined with both tiny claws to help it feed, and long antennae to sense its surroundings. The study's lead author says species today don't have limbs that function like that. "This dual function is very, very special, because it does not appear in modern forms. If you take insects as an example, they have a...
  • Giant Ocean Arthropod Rivals Largest in History

    A trio of paleontologists has announced the discovery of a fossil belonging to a new species of ancient arthropod that rivals the largest ever found. They detail their finding in Wednesday's publication of the journal Nature. Hundreds of millions of years ago, arthropods, which include modern-day spiders, insects, and crustaceans, were much larger, and we're not talking the size of a small dog. An extinct millipede called Arthropleura reached up to 8.5 feet in length, making it the largest land invertebrate ever known to exist. Jaekelopterus rhenaniae, which extended 8.2 feet, dwelled in the water (pictured right).

    Tail-gliding Bugs Are Not Evidence for Flight Evolution by Jeffrey Tomkins, Ph.D.* Researchers recently announced that they have unlocked some of the mystery surrounding the evolution of insect flight.1 Their observance of a certain wingless insect led them to hypothesize that its “directed aerial descent” might be an important stage in flight evolution. But is it?...

    Stalin's last army: hordes of gigantic crabs on their way to invade Europe - By Julius Strauss in Kirkenes, Northern Norway Millions of giant Pacific crabs, whose ancestors were brought to Europe by Joseph Stalin in the 1930s, are marching south along Norway's coast, devouring everything in their path.The monster crabs, which can weigh up to 25lb and have a claw-span of more than three feet, are proving so resilient that scientists fear they could end up as far south as Gibraltar. Energised by a mysterious population explosion a decade ago, whole armies of the crustaceans - known as the...

    WASHINGTON - Will you walk into my parlor, said a Cretaceous spider to an ancient fly. The classic spider's web, like Charlotte would have woven, was invented just once, way back in the Cretaceous period some 136 million years ago, scientists report. Called an orb web, it's the generally circular style spun by two major types of spiders, which had raised the possibility of the two groups evolving this form separately. But a paper in Friday's issue of the journal Science says a comparison of the spider genes related to web making shows that the orb web developed just...
