“…Paleozoic outcrops in Sonora, NW Mexico (compiled from 1:50,000 maps of the Servicio Geológico Mexicano and González-León et al, 2006). but different from those from the western United States (Poole et al, 2005;Boucot et al, 2008;Navas-Parejo et al, in press). Ocean-basin rocks, previously referred to as eugeoclinal or eugeosynclinal rocks, and currently known as the Sonora allochthon (Poole and Madrid, 1988;Stewart et al, 1990, p. 187;Poole et al, 2005), crop out in central Sonora (Figures 1, 3).…”

“…The Sonora allochthon is divided into two successions: pre mid-Mississippian preorogenic strata, and a mid-Mississippian-Late Pennsylvanian synorogenic succession (Poole et al, 2005(Poole et al, , 2008. Correlation of the Sonora allochthon with other orogenic segments that currently crop out in Texas (Marathon Region), Oklahoma (Black Knob Ridge), and Arkansas (Ouachita Mountains) is based both on lithology and fossil associations (Peiffer-Rangin, 1979Noll et al, 1984;Poole et al, 2005;Boucot et al, 2008). Upper Paleozoic rocks from northern Baja California have been correlated also with the Sonora allochthon (Gastil, 1993;Poole et al, 2005;Navas-Parejo et al, 2018).…”

A thorough review of the available literature regarding biostratigraphic studies on the Carboniferous sedimentary rocks of Sonora, northwestern Mexico, is presented here. Most frequently reported fossils are marine invertebrates as well as protozoans and vertebrate remains. Most abundant groups are corals, both solitary and colonial, fusulinids and other foraminifera, conodonts, and brachiopods. Less commonly described groups are crinoids, algae, bryozoans, and radiolarians. This revision evidences the high paleobiodiversity and potential research interest of the Carboniferous geological record of Sonora. Although published studies including paleontological information greatly lack detailed specific taxonomic determinations or biostratigraphic analyses, the presence of all Mississippian and Pennsylvanian stages can be inferred. Regional stratigraphic gaps and hiatuses, however, are difficult to determine because of this scarcity of precise datings. Current lithostratigraphic units defined formally or informally are also reviewed.

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.

In many parts of the world, the base of the Devonian is generally characterized by the prevailing onset of carbonate sedimentation. The index fossil for the base of the Lochkovian is the graptolite Monograptus uniformis Přibyl, 1940; however, because of dominating carbonates, the lowermost Devonian stratigraphy must rely on other faunal groups, especially conodonts. Owing to their abundance in carbonate successions and their global distribution, in many cases conodonts are the only faunal group that permits recognition of the Silurian-Devonian boundary (corresponds to the conodont hesperius-optima Zone). In many studies over the past decades conodont zonations for the uppermost Přídolí and the lowermost Lochkovian had been established (e.g.
