“…Chronostratigraphy uses the Heerlen regional scheme as summarised by Wagner (1974), Wagner and Winkler Prins (2016) and Knight et al (2023) as this gives a better stratigraphical resolution in these terrestrial successions than the IUGS Global Chronostratigraphy (Cohen et al, 2013). is contrary to accepted nomenclatural practice as laid down in the ICN, where the earliest published family name must be used whose type can be included within the family.…”

Seven fossil–species can be distinguished within the range of late Carboniferous and early Permian equisetopsid (“horsetail”) foliage formerly assigned to Annularia stellata. The shoots bearing this foliage also produced distinctive strobili often known as Calamostachys tuberculata. These foliage species can be differentiated by leaf and whorl morphology, and each species has a distinct geographical and stratigraphical range. The group first appeared in the intramontane basins of the Variscan Mountains in the late Duckmantian, and then expanded into the lowland paralic coal swamps in the Bolsovian–Asturian. The group continued to flourish in coal swamp refugia during the Stephanian but eventually disappeared during the early Permian.

“…The majority of fossil ricinuleids, however, originate from the Atokan and Desmoinesian (Moscovian) stages of the Pennsylvanian (ca. 308-315 Ma) (Selden, 1992;Wagner and Winkler Prins, 2016). The North American specimens occur primarily in the Pennsylvanian Fossil-Lagerstätte of Mazon Creek, Grundy Co., Illinois, apart from a single specimen from Morris, Oklahoma (Selden, 1992).…”

A new, giant ricinuleid (Arachnida, Ricinulei), from the Pennsylvanian of Illinois, and the identification of a new, ontogenetically stable, diagnostic character

A new fossil ricinuleid, Curculioides bohemondi n. sp., from the Pennsylvanian Energy Shale of Illinois is described from a single specimen. It is the largest ricinuleid species yet described, living or extinct. The Energy Shale represents a new geographic locale for fossil ricinuleids, a sparsely distributed group. The species is distinguished from other members within the genus by the possession of very large (0.09 mm) carapace tubercles at a very low (30 mm-2) density. Statistical analyses are performed on extant and fossil ricinuleids to determine how their tubercles change throughout ontogeny, culminating in the recovery of a new ontogenetically stable diagnostic character: the tubercle coefficient (a measure of the size of the tubercles relative to body size).

“…Pfefferkorn and Gillespie 1980;Blake et al 2002) but their taxonomy and biostratigraphy have not been investigated in detail in recent years, making a comparison with the data from the more easterly basins difficult. We will hereafter use the Heerlen Regional Chronostratigraphy, as reviewed by (Wagner 1974) and Wagner and Winkler Prins (2016) as this still provides a far better temporal resolution of the terrestrial coal-bearing sequences of Variscan Euramerica; for a correlation between this scheme and the IUGS Global Chronostratigraphy based mainly on marine stratotypes, see Fig. 2.…”

The floristic relationship between the upland and lowland Carboniferous wetlands of Variscan Euramerica — Evidence from some medullosalean pteridosperm fronds

Alethopteris grandinii represents remains of fronds of a medullosalean pteridosperm (probably a small tree) that rapidly migrated across the lowland wetland habitats of Variscan Euramerica in middle Asturian (late Moscovian) times. This was probably caused by changing drainage patterns within the lowland coal swamps, in response to climate and landscape changes. However, these medullosaleans had first appeared rather earlier, in early Bolsovian (early Moscovian) times, in upland wetland habitats. These upland habitats may have pre-adapted these plants to the changed condition in the lowland coal swamps.
