2024 In Paleontology

picture info	2024 In Paleontology Flora Plants "Algae" Fungi Newly named fungi Mycological research * Garcia Cabrera & Krings (2024) describe fungi colonizing bulbils of ''Palaeonitella, Palaeonitella cranii'' from the Devonian Rhynie chert, interpreted as distinct from fungi colonizing the axes and branchlets of ''P. cranii'', which might indicate organ-specific colonization. Cnidarians New taxa Cnidarian research * Yong ''et al.'' (2024) report evidence of presence of a thin, transverse wall spanning the internal thecal cavity of specimens of ''Olivooides, Olivooides mirabilis'' and ''O. multisulcatus'' from the Cambrian Kuanchuanpu Formation (Shaanxi, China), representing the earliest known transverse exoskeletal element in cnidarians reported to date. * A study on the phylogenetic relationships of Hexangulaconulariidae, based on data from new specimens from the Cambrian strata from the Yangtze Platform (China), is published by Song ''et al.'' (2024), who interpret hexangulaconulariids as members of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Rugosa The Rugosa or rugose corals are an extinct Class (biology), class of solitary and Colony (biology), colonial corals that were abundant in Middle Ordovician to Late Permian seas. Solitary rugosans (e.g., ''Caninia (genus), Caninia'', ''Lophophyllidium'', ''Neozaphrentis'', ''Streptelasma'') are often referred to as ''horn corals'' because of a unique horn-shaped chamber with a wrinkled, or wiktionary:rugose, rugose, wall. Some solitary rugosans reached nearly a meter (3 ft 3 in) in length. However, some species of rugose corals could form large colonies (e.g., ''Lithostrotion''). When radiating septa were present, they were usually in multiples of four, hence ''Tetracorallia'' in contrast to modern ''Hexacorallia'', colonial polyps generally with sixfold symmetry. Rugose corals have a skeleton made of calcite that is often fossilized. Like modern corals (Scleractinia), rugose corals were invariably benthic, living on the sea floor or in a reef-framework. Some symbiotic rugose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Xylariales The Xylariales are an order (biology), order of fungi within the class (biology), class Sordariomycetes (also known as Pyrenomycetes), subdivision Pezizomycotina, division (mycology), division Ascomycota. It was the original order of the Class (taxonomy), subclass Xylariomycetidae. Xylariales was circumscription (taxonomy), circumscribed in 1932 by Swedish mycologist John Axel Nannfeldt, and Xylariomycetidae by Ove Erik Eriksson and Katarina Winka in 1997. Taxonomy Early classifications of the Xylariales varied considerably, with taxonomists recognising anywhere from three to eleven family (biology), families within the order. A milestone in understanding the order's composition came from Smith, Liew, and Hyde's 2003 molecular phylogenetics study, which established the Xylariales as a monophyletic group containing seven families: Amphisphaeriaceae, Apiosporaceae, Clypeosphaeriaceae, Diatrypaceae, Graphostromataceae, Hyponectriaceae, and Xylariaceae. During this period, fungi in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
