The Baoshan region of Yunnan Province, SW China, is one of the best locations to study Wenlock to Pridoli conodonts in China. Detailed analysis of conodont collections from the Silurian strata (the “Lichaiba” and Niushiping formations) of the Laojianshan section in the Baoshan region resulted in revised dating of the section. In stratigraphically ascending order, the Pterospathodus amorphognathoides amorphognathoides Zonal Group, the Pterospathodus pennatus procerus Superbiozone (probably only the Lower Pterospathodus pennatus procerus Biozone), the Ozarkodina sagitta sagitta Biozone, the Kockelella ortus absidata Biozone, the Kockelella crassa Biozone, the Polygnathoides siluricus Biozone and the “Ozarkodina” eosteinhornensis s.l. Interval Biozone are recognised. The conodont faunas recovered indicate that the “Lichaiba Formation” corresponds to the upper Telychian–upper Wenlock, and the Niushiping Formation to the Ludlow–Pridoli. Part of the Ireviken Event, that is, from Datum 3 to Datum 4 can be recognised from the studied section. The late Telychian conodont fauna from the Laojianshan section is characteristic of distal, open‐shelf depositional environments.

“…alternata was identified (Figures and l,s). So far, W. alternata has been only known from the Pridoli of the Carnic Alps (Corradini et al, ; Corradini & Corriga, , ). Hence, probable recognition of this conodont species in Landslide B might indicate that these beds without Pol.…”

“…Also, Corradini et al . (2020) reported that P. biexoramus occurs in lowermost Devonian strata at the Monte Cocco II section in the Carnic Alps with forms assigned to ‘ C. hesperius ’. The upper ranges of the two new Caudicriodus species are constrained only by their disappearances well below the first appearance of Lanea omoalpha Murphy & Valenzuela‐Ríos, 1999 in West Texas (Barrick et al .…”

Two Caudicriodus species from lowermost Devonian strata in southern Laurentia (Texas-Oklahoma-Western Tennessee), C. anitae sp. nov. and C. murphyi sp. nov., are endemic forms that appeared during the positive d 13 C excursion associated with the Klonk Event. The other Caudicriodus species that occur during the Klonk Event and that are often used to recognize the base of the Devonian, C. hesperius and C. woschmidti, differ in that the I elements of the southern Laurentia species possess a middle row of nodes on the transverse ridges of the spindle. The apparatus of C. murphyi sp. nov. possesses three groups of elements in addition to the I element: F elements (short wide coniforms); D elements (denticles on the posterior margin) and C elements (slender coniforms with basally flaring costae). Strong provinciality in slightly younger Lochkovian Caudicriodus species was demonstrated earlier, and we propose that Caudicriodus species radiated independently into endemic species in different geographic regions just before or during the Klonk Event. A form originally described as C. woschmidti hesperius by Simpson (1998) is reinterpreted as a late Ludlow-Pridoli species of Praeicriodus, P. simpsoni sp. nov., with an I element and apparatus structure probably ancestral to Caudicriodus.
