Juresaniinae
subfamily of brachiopods (fossil)
Juresaniinae is an extinct subfamily of brachiopods which lived during the Carboniferous and Permian periods in marine habitats.
Taxonomy
The exact evolutionary relationships of Juresaniinae relative to other groups of the suborder Productidina have been a matter of extensive debate throughout much of the 20th Century, primarily due to the three genera Buxtonia, Pustula and Juresania (with the debate later expanded to their families and subfamilies) shifting in position repeatedly between phylogenies and classifications. The emphasis on internal versus external characters to determine the systematics of these groups has largely been responsible for this: the original Treatise on Invertebrate Paleontology published in 1965 placed emphasis on internal characters (including the cardinal process) as diagnostic, whereas the 2000 revision primarily used external features and shell shape, resulting in differing classification of these clades.
More recently, Leighton & Maples (2002) conducted multiple phylogenetic analyses which are strongly in agreement that the four subfamilies Buxtoniinae, Echinoconchinae, Pustulinae and Juresaniinae form the family Echinoconchidae, and that Juresaniinae was more closely related to Echinoconchinae than to Buxtoniinae.
“Juresaniinae” enters the record as subfamily of brachiopods (fossil). Crown Archives preserves that source wording while asking what Juresaniinae, subfamily and brachiopods can confirm, complicate or overturn.
Why this record matters
“Juresaniinae” is worth following because a concise public description often conceals a longer documentary argument. Here, Juresaniinae, subfamily and brachiopods provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 14, 2023. The linked authority identifier is Q33138821. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1965, 2000 and 2002.
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.
