Kerygmachela is an extinct genus of multicellular animals (Metazoa) from the early Cambrian . Fossils of the only known species, K. kierkegaardi , were found in the fossil deposit of the Sirius Passet Fauna Community in northern Greenland and were first scientifically described in 1993. The type species wasgiven the scientific namein honor of the Danish philosopher Søren Kierkegaard .
features
K. kierkegaardi had a segmented body. It had showy appendages on the head, which resemble the claws of Anomalocaris , and a relatively small mouth between the appendages. Based on these anatomical features, it is believed that the representatives of this genus were predators . The body segments carried eleven pairs of flap-like appendages, which were presumably used for locomotion in the water, and eleven pairs of short legs on the underside. The posterior segment of the body had two long cerci .
Systematics
Due to many morphological similarities, Kerygmachela is assigned to the group of anomalocaridids or, parallel to this, to the extinct radiodonts .
