“…Additionally, conodont Acodusonestensis and radiolaria Entactinia complanate from chert beds interlayered within pillow lava imply an Early to Middle Ordovician age for the Erlangping back‐arc Ocean (Wang et al, 1995). Although 14 radiolarian species from the interlayered radiolarian cherts in the lower Damiao Formation assigned an Ordovician to Silurian age (Wang, 1989), these radiolaria species are uncertain and unassessed until now (Rees, 2022).…”

Ordovician tectonic transition from passive margin into peripheral foreland in the southern Ordos: A diagnostic insight into the closure of Erlangping Ocean between the North Qinling Arc and North China Block

Achieving a reliable closure time of a back-arc ocean is an essential aspect in studies on detailed tectonic processes of an active continental margin and arc-continent collision. This is particularly the case for the northern Qinling Orogen, which records the accretion of the North Qinling Arc (NQA) onto the North China Block (NCB) after the Erlangping back-arc ocean closure. Sedimentological, petrological and geochronological signatures from the Ordovician successions in the southern Ordos reveal a tectonic transition from passive continental margin to peripheral foreland in the southern NCB at the beginning of Katian. Sedimentological and geochronological investigations reveal an abrupt shift of accelerating basin subsidence and deepening at the earliest Katian, separating ca. 300-m-thick shallow-marine carbonate shelf assemblages from overlying ca. 2000-m-thick deep-water carbonate slope and turbidite associations. Zircon age spectra of the Katian turbidites are characterized by early-Palaeozoic and Neoproterozoic age clusters, which are different from those of the Middle Ordovician quartz arenites sourced merely from the NCB basement. Instead, these age patterns match well with those of the coeval successions in the northern NQA, indicating a spatially linked abyssal deposystem. Stratigraphic architecture deciphers a typical foreland basin geometry, involving, from south to north, northward-propagating turbiditic wedge, northward-backstepping carbonate slope and progressively shoaling carbonate platform, embodying foredeep, forebulge and backbulge, respectively. These characteristics of basin-fill evolution reflect the northward migration of the flexural wave as a dynamic response to the northward expansion of the thickened NQA thrust wedge. Together with the other geological and geochronological data, our new insights indicate a southward subduction polarity of the Erlangping back-arc oceanic crust followed by its termination at ca. 450 Ma, which was earlier than that of the main Proto-Tethyan Shangdan Ocean between

“…As a large number of names were generated, special care was taken to identify and mitigate collisions between validly published and Candidatus taxonomic names and the new names proposed here. To do this, a custom algorithm was implemented to check every proposed taxon against entries in the Catalogue of Life 93 , the NCBI database 94 , the Interim Register for Marine and Nonmarine Genera 95 and the list of Candidatus taxa 96 . The algorithm first searches for exact matches within these data sources, then uses an Rcpp implementation (10.6084/m9.figshare.3386308.v1) of the Damerau-Levenshtein (DL) distance algorithm to identify taxon names with an edit distance of 2 or less from an existing taxon.…”

Hyperactive nanobacteria with host-dependent traits pervade Omnitrophota

et al. 2023

Candidate bacterial phylum Omnitrophota has not been isolated and is poorly understood. We analysed 72 newly sequenced and 349 existing Omnitrophota genomes representing 6 classes and 276 species, along with Earth Microbiome Project data to evaluate habitat, metabolic traits and lifestyles. We applied fluorescence-activated cell sorting and differential size filtration, and showed that most Omnitrophota are ultra-small (~0.2 μm) cells that are found in water, sediments and soils. Omnitrophota genomes in 6 classes are reduced, but maintain major biosynthetic and energy conservation pathways, including acetogenesis (with or without the Wood-Ljungdahl pathway) and diverse respirations. At least 64% of Omnitrophota genomes encode gene clusters typical of bacterial symbionts, suggesting host-associated lifestyles. We repurposed quantitative stable-isotope probing data from soils dominated by andesite, basalt or granite weathering and identified 3 families with high isotope uptake consistent with obligate bacterial predators. We propose that most Omnitrophota inhabit various ecosystems as predators or parasites.

“…The most obvious is a deficiency in scale. Comparable efforts for eukaryotes document hundreds of thousands of genera and millions of species (http://www.catalogueoflife.org/annualchecklist/2019/info/about) [7]. Although estimates of the total number of bacterial and archaeal species vary from millions to billions [8,9], even the most conservative figures amply document an unmet need for many millions of new names for genera and species of Archaea and Bacteria.…”
