A giant shrimplike animal with filter feeding, like later whales.:-http://www.livescience.com/44381-filter-feeding-cambrian-creature-unearthed.html?cmpid=556803-"The new creature was unearthed in sediments known as the Sirius Passet formation. These shale-like deposits are teeming with primeval organisms from the evolutionary "big bang' known as the Cambrian explosion, a period between 540 million and 493 million years ago when most complex life on Earth emerged. [See Images of the Giant Cambrian Creature]
 
"Before then, most life forms were bacteria or microbial mats, but during the Cambrian hard exoskeletons, jointed limbs, compound eyes and antennae evolved.-
"While on an excavation trip in 2009, the team unearthed fragments of strange feeding appendages attached to a head shield from an unknown creature. The appendages, which date to about 520 million years ago, belonged to a group known as anomalocarids, the top predators of their day."-Anomalocarids were found originally in the Canadian Burgess shale.
