Fossils of Cambrian Predator Preserved With Brain Impressions

An anonymous reader writes "Researchers on Wednesday described fossilized remains unearthed in China showing in fine detail the brain structures of a bizarre group of sea creatures that were the top predators more than half a billion years ago. The 520-million-year-old creature, one of the first predators of its day, sported compound eyes, body armor and two spiky claws for grabbing prey. "The animals of the Cambrian are noted for being a collection of oddballs that are sometimes difficult to match up with anything currently living on Earth. But even among these oddities, Anomalocarids stand out (as their name implies). The creatures propelled themselves with a series of oar-like paddles arranged on their flanks, spotted prey with enormous compound eyes, and shoveled them into a disk-like mouth with large arms that resided at the very front of their bodies—although some of them ended up as filter feeders."

    "The animals of the Cambrian are noted for being a collection of oddballs that are sometimes difficult to match up with anything currently living on Earth."

    You can say that again, Anomalocaris is a good example. The feeding appendages of this creature were initially identified as a type of lobster, it's body was identified as a species of sponge while the mouth was identified as a jellyfish. It was only later that people finally realized these finds were the components parts of a single critter. It makes one wonder what kind of weird creatures exist on other planets and if we'd even recognize them as life if we saw them.

      When it comes to weird shit that exists... Tardigrades take the cake.

      They can live 10 years without any type of sustenance, can withstand more pressure than exists in the deepest oceans, can be boiled, frozen, blasted with radiation, even thrown in space, and still survive.

    Actually, they are considered pan-arthropoda, a greater group, that includes the arthropoda, but also the tardigrades and the onychophora, and if they are indeed related to the velvet worms, they would be classified as onychophora and not arthropoda. And yes, they are connected, in the same sense that all protostomia are connected.

    In order to protect turf and progeny from your own species. One's own species is often the fiercest competition in the local ecology.
