“…-Metadimorphoceras has an almost global distribution and 23 valid species are listed in the AMMON database (Korn & Ilg 2010); these derive from a wide stratigraphic interval ranging from the middle Late Viséan Goniatites crenistria interval to the Kinderscoutian R 1 Zone in Europe (Moore 1939) and even in the Yeadonian G 1 Zone in Arkansas (Manger 1988). Separation of species is almost completely based on suture line characters.…”

“…-Metadimorphoceras richardsi belongs to the simple-sutured species of the genus (Manger 1988), showing a degree of complexity comparable to the late Asbian (British P 1 a Zone) M. pseudodiscrepans (Moore, 1939), which, however, already shows a further subdivision of the external lobe. A similar complexity stage, but also with a weak tertiary subdivision of the external lobe, is visible in the early Brigantian M. hodsoni Moore, 1958.…”

The ammonoid faunas from the Goniatites Zone (Late Viséan; Mississippian) of the Camp Canyon Member (Chainman Formation) are described for the first time. The assemblage shows close relationships to time equivalent occurrences in Alaska and the American Midcontinent, but differs markedly from occurrences in Europe, North Africa, and the South Urals. Seven successive ammonoid biozones are proposed for this interval in North America, in ascending order: (1) Calygirtyoceras confusionense Ammonoid Biozone, (2) Calygirtyoceras arcticum Ammonoid Biozone, (3) Girtyoceras primum Ammonoid Biozone, (4) Girtyoceras gordoni Ammonoid Biozone, (5) Goniatites deceptus Ammonoid Biozone, (6) Goniatites eganensis Ammonoid Biozone, and (7) Goniatites multiliratus Ammonoid Biozone. The following ammonoid species are revised or newly described: Bollandoceras occidentale sp. nov., Entogonites burbankensis sp. nov., Entogonites borealis (Gordon, 1957), Entogonites acus sp. nov., Calygirtyoceras confusionense sp. nov., Calygirtyoceras arcticum Gordon, 1957, Girtyoceras primum sp. nov., Girtyoceras gordoni sp. nov., Girtyoceras hamiltonense sp. nov., Dimorphoceras worki sp. nov., Dimorphoceras rileyi sp. nov., Metadimorphoceras mangeri sp. nov., Metadimorphoceras richardsi sp. nov., Kazakhoceras bylundi sp. nov., Goniatites americanus Gordon, 1971, Goniatites deceptus sp. nov., Goniatites eganensis sp. nov., Goniatites sowerbyi sp. nov., and Praedaraelites loeblichi (Miller and Furnish, 1940)

“…Separation of species is almost completely based on suture line characters. Twelve of the species were erected on material from Europe; these derive from a wide stratigraphic interval ranging from the middle Late Visan Goniatites crenistria interval to the Kinderscoutian R1 Zone in Europe (Moore 1939) and even in the Yeadonian G1 Zone in Arkansas (Manger 1988 grouped as follows (for a phylogenetic concept of the genus, see Manger 1988):…”

Five Late Viséan ammonoid assemblages of North Variscan provenance are described from the locality Chebket el Hamra (Jerada Basin, north‐eastern Morocco). These assemblages are composed of 27 species of the genera Eoglyphioceras, Girtyoceras, Sulcogirtyoceras, Metadimorphoceras, Goniatites, Arnsbergites, Hibernicoceras, Paraglyphioceras, Lusitanoceras, Sudeticeras, Neoglyphioceras, Lusitanites, Ferganoceras, Praedaraelites, and Pronorites. The new subfamily Arnsbergitinae is described, as well as the thirteen new species Eoglyphioceras minutum n. sp., Girtyoceras ibnkhaldouni n. sp., Metadimorphoceras anguinosum n. sp., Arnsbergites ferrus n. sp., Arnsbergites proiecturus n. sp., Arnsbergites rufus n. sp., Hibernicoceras touissitense n. sp., Hibernicoceras artilobatum n. sp., Paraglyphioceras celeris n. sp., Lusitanoceras zirari n. sp., Sudeticeras ibnbajjahi n. sp., Sudeticeras horoni n. sp., and Pronorites owodenkoi n. sp.
