The species was described according to the holotype OUMNH C.29614 in 2013 [2] . A fossil of this species was found in England ( Herefordshire ) in rare preservation: not only the external skeleton , but also soft tissues, including limbs, eyes, gills and the digestive system, were fossilized. Launching the found sample layer by layer, we managed to create a complete three-dimensional model of the animal.
