Computer modeling of the Anomalocaris mouthparts suggests they were in fact better suited to sucking on smaller, soft-bodied organisms.[45] Although Whittington and Briggs concluded that Anomalocaris did not fit into any known phylum, research since the 1990s has concluded that it was closely related to Opabinia and to the ancestors of arthropods.[6] In 2009 a fossil named Schinderhannes bartelsi, an apparent relative of Anomalocaris, was found in the Early Devonian period, about 100 million years later than the Burgess Shale.[46] Conway Morris gave Hallucigenia its name because in his reconstruction it looked bizarre – a worm-like animal that walked on long, rigid spines and had a row of tentacles along its back.[47] Science fiction author Greg Bear says the Jarts in his The Way stories were scaled-up versions of this reconstruction.[48] However, in the late 1980s Lars Ramsköld literally turned it over, so that the tentacles, which he found were paired, became legs and the spines were defensive equipment on its back.
