Homosclerophorida
order of sponges
Homosclerophorida is an order of marine sponges that belongs to the monotypic class Homoscleromorpha. Members of this family are exclusively marine, inhabiting shallow waters. The order is small, comprising somewhat more than 100 described species. These species are placed into around seven genera that belong to one of two families: Plakinidae and Oscarellidae.
The fossil record of Homosclerophorid sponges is poor because of to their sometimes present reduced and poorly organized siliceous skeleton. Their fossil record goes back at least to the early Carboniferous period. They also have fossil records during the Early and Upper Jurassic period.
Taxonomy
Homoscleromorpha is recognized as the fourth class of sponges being phylogenetically well separated from Demospongiae and other sponge groups. On the basis of molecular and morphological evidence, the two families Plakinidae and Oscarellidae have been reinstated. There are 136 species in this group that are divided into 10 genera.
“Homosclerophorida” enters the record as order of sponges. Crown Archives preserves that source wording while asking what Homosclerophorida, order and sponges can confirm, complicate or overturn.
Why this record matters
“Homosclerophorida” is worth following because a concise public description often conceals a longer documentary argument. Here, Homosclerophorida, order and sponges provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 3, 2026. The linked authority identifier is Q13140211. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
