dbo:abstract | Els estilòfors (Stylophora) són una classe extinta d'equinoderms homalozous que van viure del Cambrià mitjà al Devonià mitjà. (ca) Los estilóforos (Stylophora) son una clase extinta de equinodermos homalozoos que vivieron del Cámbrico Medio al Devónico Medio. (es) The stylophorans are an extinct, possibly polyphyletic group allied to the Paleozoic Era echinoderms, comprising the prehistoric cornutes and mitrates. It is synonymous with the subphylum Calcichordata. Their unusual appearances have led to a variety of very different reconstructions of their anatomy, how they lived, and their relationships to other organisms. Stylophorans have played a major role in debates over the origin of chordates, as under the calcichordate hypothesis they were interpreted as being stem-group chordates. However, multiple lines of evidence argue against the calcichordate hypothesis, and stylophorans are now widely agreed to belong to the echinoderm total group. Debate remains over whether they are stem-group echinoderms which predate the origin of radial symmetry, or highly modified descendants of radially symmetric echinoderms.

(fr) 스틸로포라(Stylophora)는 고생대에 살았던 극피동물의 일종이다. 극피동물이면서 몸이 오방사대칭이 아니고, 오히려 비대칭이다. 다른 극피동물들과의 유연관계에 대해서는 확실하게 밝혀진 것이 아직 없다. 과거에는 해과류(海果綱, Homalozoa)라는 원시적 극피동물을 묶은 분류군의 일종으로 취급하였는데, 이는 하나의 진화적 계통을 나타낸다기보다는 원시적인 종류들의 임의적 집합에 가까운 분류군이다. 스틸로포라는 크게 코누트(분류군 Cornuta, 개체 Cornute)와 미트레이트(분류군 Mitrata, 개체 Mitrate)로 나뉜다. 이 중 코누트는 하나의 진화 계통이 아닌, 미트레이트보다 먼저 분기한 종들의 집합일 뿐이라는 견해가 있다.
