The Pennsylvanian ammonoidsGastrioceras magoffinensen. sp.,Maximites nassichukin. sp.,Dimorphoceratoides adamsin. sp.,Bisatoceras? sp.,Phaneroceras chesnutin. sp., and Christioceratidae gen. indet. occur in the Magoffin Member of the Four Corners Formation in eastern Kentucky. The interval represented by the Magoffin ammonoid fauna should be known as theGastrioceras magoffinenseAssemblage Zone. This overlies the well-knownDiaboloceras neumeieriZone, represented in the Kendrick Shale Member of the Hyden Formation in eastern Kentucky. TheGastrioceras magoffinenseZone correlates to theDiaboloceras varicostatum–Winslowoceras henbestiZone in the Winslow Member of the Atoka Formation in northwestern Arkansas. Ammonoids and associated conodonts, includingDeclinognathodus marginodosusand its descendantD. donetzianus, indicate an early Atokan age corresponding to the basal Bolsovian (basal Westphalian C) Substage in western Europe and the Bashkirian–Moscovian Stage boundary interval in eastern Europe and the South Urals.

Stratigraphic Position

Abstract. The ammonoid fauna from the Late Devonian Three Forks Shale of Montana is revised. Six taxa were recognised, which belong to the genera Tornoceras, Pernoceras, Raymondiceras, Platyclymenia, Pleuroclymenia, and Carinoclymenia. The ammonoid assemblage suggests a stratigraphic position within the middle Famennian, most probably the Platyclymenia annulata Zone. The ammonoids display extreme septal crowding in intermediate as well as adult growth stages, which can be regarded as evidence for instable palaeoecological conditions during lifetime of the animals. Die Ammonoideenfauna aus dem oberdevonischen Three Forks Shale von Montana wird revidiert. Sechs Taxa werden unterschieden; sie gehören zu den Gattungen Tornoceras, Pernoceras, Raymondiceras, Platyclymenia, Pleuroclymenia und Carinoclymenia. Die Ammonoideen-Vergesellschaftung spricht für eine stratigraphische Position im mittleren Famennium, wahrscheinlich in der Platyclymenia annulata Zone. Die Ammonoideen zeigen auffällige Drängung der Septen in intermediären und adulten Wachstumsstadien, die als Hinweis auf instabile Lebensbedingungen für die Tiere gewertet werden kann. doi:10.1002/mmng.200600008

Ammonoid Fauna

A small ammonoid fauna, of probable middle Early Tournaisian age, is described from the Gara el Kahla near Timimoun, Gourara, Algerian Sahara. The following taxa are described: <i>Acutimitoceras algeriense</i> n. sp., <i>Acutimitoceras sinulobatum</i> n. sp., <i>Acutimitoceras</i> sp. A, <i>Hasselbachia gourara</i> n. sp., <i>Gattendorfia jacquelinae</i> n. sp., <i>Gattendorfia</i> cf. <i>crassa</i> Schmidt. 1924, <i>Kahlacanites</i> n. gen., <i>Kahlacanites meyendorfi</i> n. sp., <i>Kahlacanites mariae</i> n. sp., and <i>Kahlacanites timimounensis</i> n. sp. <br><br> Eine kleine Ammonoideenfauna mit wahrscheinlich mittlerem Untertournai-Alter von der Gara el Kahla bei Timimoun (Gourara, Algerische Sahara) wird untersucht. Die folgenden Taxa warden beschrieben: <i>Acutimitoceras algeriense</i> n. sp., <i>Acutimitoceras sinulobatum</i> n. sp., <i>Acutimitoceras</i> sp. A, <i>Hasselbachia gourara</i> n. sp., <i>Gattendorfia jacquelinae</i> n. sp., <i>Gattendorfia</i> cf. <i>crassa</i> Schmidt, 1924, <i>Kahlacanites</i> n. gen., <i>Kahlacanites meyendorffi</i> n. sp., <i>Kahlacanites mariae</i> n. sp. und <i>Kahlacanites timimounensis</i> n. sp. <br><br> doi:<a href="http://dx.doi.org/10.1002/mmng.20040070107" target="_blank">10.1002/mmng.20040070107</a>
