Butterflies, lobsters, and spiders are surviving relatives of a species called Yawunik Kootenayi – a marine organism with two-paired-eyes and grasping appendages that existed 508 million years back, even 250 million years prior to when the dinosaurs surfaced.
Where Was The Fossils Found?
An international group of esteemed palaeontologists based at the prestigious University of Toronto and at Royal Ontario Museum, Toronto and Pomona College, California identified this unprecedented fossil. The fossil was an element of the esteemed and renowned fossil deposit called Canadian Burgess Shale deposits. This newly found initial species on earth’s crust was found in the Marble Canyon website.
Yawunik had extended frontal appendages – ones that resembled antennae of shrimps or beetles. These appendages composed of lengthy claws; two of these were placed opposite to one another and had rows of teeth that would help any animal catch hold of the prey.
Features Of The Creature
The creature had distinct predatory and anatomy habits, akin to the initial arthropods – the family of lobsters and spiders. Cedric Aria, the lead author of this exquisite study and a Ph.D candidate mentioned that the creature had certain attributes of arthropods, with external skeleton, joined appendages and segmented physiques. There were certain typical traits that are observable even in the modern day arthropods.
This study reveals that Yawunik used to move its set of frontal appendages forward and back. It also possessed whip-like flagella which extended from the very tip of their claws, thus making the appendages versatile and a bit complicated. Unlike crustaceans or insects, this creature never possessed any appendage on the head region.
The site (Marble Canyon) wherein this fossil has been found is approximately 40 kilometres south of Burgess Shale area in British Columbia’s Yoho National Park. Researchers said that abundant number of Yawunik species fossils is available in Marble Canyon and would play a pivotal role in its study.
