Newly Discovered Cambain Era Predator Precurser to Arthropods

March 31, 2015

Paleontologists are swimmingly ecstatic over the discovery of four eyed predator has two powerful arms that are thought to have evolved into the modern day arthropods claws, such as those of a lobster. Others theorize that they may have developed into spiders and become the mouth parts of the arachnid.

Behance reported that this little crustacean cruised the seas about 508 million years ago during the Cambrian period. Unlike modern arthropods, whose legs have extremely specialized functions, each leg performing a very specific task, this wonder of the deep was able to use the front legs for hunting and grabbing prey.

Yawunik kootenayi was introduced to the world via the March 27th edition of the Palaeontology journal, although it was discovered in 2012 in Marble Canyon of British Colombia’s Kootenay National Park. It was found fossilized in the plentiful fossil beds of the canyon and is about six inches long.

Its legs are its most distinguishing feature and are composed of fine filamentous tendrils that functioned like whipping flagella, and that extend from each of three claws, two of which contain long rows of teeth like structures. It is believed that the creature could use its flagella appendages to sweep water back and forth, spread them out to aid in the event of an attack and that the arms would remain tucked under as it swam.

The area it was found in is being protected.
