Kerygmachela Kirkegaardi

10 tons made models and designed the exhibition about Sirius Passet fossils.

This animal lived in the ocean 520 million years ago, and was a gilled lobopod from the Buen Formation (Cambrian Stage 3) of the Sirius Passet Lagerstätte, in northern Greenland. Its anatomy strongly suggests that it, along with its relative Pambdelurion whittingtoni, was either an anomalocarid or a close relative thereof. The specific name, "kierkegaardi" honors Danish philosopher Søren Kierkegaard.

The fossils show an animal about 7 cm long, oval in shape with a round mouth on the underside and 11 wide flaps along each flank. The flaps have probably been a kind of swimming fins that could propel the animal through the water through a coordinated wave motion.
The Three approximately seven centimeters long spikes - two at the front and one at the back - may have been some kind of sensors, and on the head two powerful 'fangs' may have fed food into the mouth.

In 2018, danish scientist found new fossils in such pristine conditions, that they were able to see their eyes and internal organs, including the brain! This is a new piece of the puzzle of evolution concerning development of the brain, as K. Kierkegaardi is is considered an ancestor of the arthropods - that is insect, mites, spiders and crustaceans.
