'''Cornuta''' is an extinct order of echinoderms. Along with the mitrates, they form the Stylophora.
Their first (probable) representative is ''Ponticulocarpus'' from the Spence Shale (mid Cambrian);<ref>{{cite journal | url = https://www.cambridge.org/core/journals/journal-of-paleontology/article/abs/ponticulocarpus-a-new-cornutegrade-stylophoran-from-the-middle-cambrian-spence-shale-of-utah/FA9710BCB74ED37D3C91B9FAA39BB86D| doi = 10.1017/S0022336000040725| title = ''Ponticulocarpus,'' a new cornute-grade stylophoran from the Middle Cambrian Spence Shale of Utah| year = 1999| last1 = Sumrall| first1 = Colin D.| last2 = Sprinkle| first2 = James| journal = Journal of Paleontology| volume = 73| issue = 5| pages = 886–891| bibcode = 1999JPal...73..886S| s2cid = 132521457| url-access = subscription}}</ref> Ordovician examples also exist.<ref name=PBDB/>
