“…sp., the Longha Formation at the Fulu Village locality yields other polymerid trilobites, agnostoid trilobites, echinoderms, brachiopods, large bivalved arthropods, bradoriids, priapulid worms, hyoliths, macroalgae, and trace fossils. This assemblage, the Fulu Biota, was recently reported by Peng et al (2020). Trilobites of the Fulu Biota at Fulu Village are commonly found as articulated exoskeletons.…”

The trilobite Liostracina has been recognized as important in taxonomic and stratigraphic studies for more than a century. Until now, the genus Liostracina and family Liostracinidae have been known from only incomplete holaspid material, a degree 2 meraspis, and protaspides. A new locality in the Longha Formation (Cambrian: Guzhangian) of southeastern Yunnan, China, yields a rich collection of articulated holaspid exoskeletons and disarticulated sclerites of a new species, Liostracina fuluensis n. sp. These specimens reveal thoracic and ventral morphology that was previously unknown for Liostracina; they demonstrate that it has a rostral plate plus rostral and connective sutures, rather than a ventral median suture on the cephalic doublure. This confirms a natant hypostomal condition for the genus. Holaspid exoskeletal features, combined with evidence of a non-asaphoid-type protaspis, indicate that Liostracina is neither a primitive trinucleoid nor a primitive asaphoid. The family Liostracinidae is excluded from the superfamily Trinucleoidea and the order Trinucleida and reassigned to the order Ptychopariida.

“…The earliest known mitrates were originally described as cornutes (Nanocarpus guoleensis) in the Furongian of Guangxi, South China (Chen & Han 2013; but see Zamora et al 2013a, b;Zhu et al 2016;Lefebvre & Ausich 2021). Similar-looking undescribed early mitrates are also possibly present in the late Guzhangian of Yunnan, South China (Peng et al 2020) and the Furongian of Korea (Lefebvre 2007a;Lefebvre et al 2016b).…”

Cornute stylophorans are a minor, though typical component of Middle-Late Ordovician echinoderm assemblages adapted to soft siliciclastic substrates, in high latitude peri-Gondwanan regions. All previously reported occurrences of Darriwilian-Katian cornutes from Czech Republic, France, Morocco and Spain are revised and their plate homologies reassessed. The genera Beryllia and Juliaecarpus are reinterpreted as junior synonyms of Domfrontia, and Thoralicystis is synonymised with Bohemiaecystis. Several Mediterranean scotiaecystids previously assigned to Bohemiaecystis and/or Scotiaecystis are placed within Thoralicarpus gen. nov., and cornute taxa originally left in open nomenclature by Chauvel are formally described as Bohemiaecystis chouberti sp. nov. (AVI) and Destombesicarpus izegguirenensis gen. et sp. nov. (AVIII). Other new Mediterranean taxa include Arauricystis clariondi sp. nov., Destombesicarpus budili gen. et sp. nov., Milonicystis reboulorum sp. nov., Thoralicarpus bounemrouensis gen. et sp. nov., and T. prokopi gen. et sp. nov. The six cornute genera identified in Darriwilian-Katian Moroccan echinoderm Lagerstätten are also present in coeval assemblages of at least one other Mediterranean region, thus supporting the existence of strong faunal affinities between the Anti-Atlas, the Armorican Massif, the Barrandian area and the Iberian Peninsula.
