Kailidiscus is an extinct genus of echinoderms which existed in what is now China during the Middle Cambrian period.[1] It was named by Yuanlong Zhao, Colin D. Sumrall, Ronald L. Parsley and Jin Peng in 2010, and the type and only species is Kailidiscus chinensis.[1] It bears close resemblance to the Burgess Shale fossil Walcottidiscus.[2]
