“…25. The Coyame Formation resembles the Lampazos Formation, with the difference being, that the Coyame yielded ammonites of Lower Albian age (Ovando-Figueroa et al 2018), and thus probably embraced the complete Lower Albian interval. The Coyame Formation is overlain by the shallow-water carbonate platform limestones of the Glen Rose Formation.…”

It is noteworthy that the lower Mural Limestone is represented by siliclastic rock, while the upper Mural Limestone and the Alisitos Formation are carbonates.The invertebrate fossils -including corals -from the Albian Espinazo del Diablo Formation in Sonora are until now poorly reported, in comparison with the above-mentioned areas. The preliminary report of the coral fauna (Baron-Szabo & González-León 1999) noted 13 species. Most of these species were not reported from the Upper Aptian to Lower Albian rocks of the nearby Mural Formation. Due to the close paleogeographic position of the coral fauna from the Bisbee Basin in the present study, a similar taxonomic composition could be expected, even if both faunas show a small difference in age. Further, the coral faunas from the Mural Formation range from the Late Aptian to Early Albian, but those from the Espinazo del Diablo Formation are of a Middle Albian age. Coral faunas, such as various Middle Albian formations (which are species-poor) of the Fredericksburg Group of the Texas platform (Wells 1933), are poorly known (Löser 2013a(Löser , 2016b. Middle Albian shallow marine corals are also known from Greece (Löser & Raeder 1995). Apart from this, all coral records of the Middle Albian are restricted to small solitary ahermatypic deep-water corals. A more detailed examination of the coral fauna of the Espinazo del Diablo Formation in Mexico does, therefore, fills a gap in the knowledge of Albian coral faunas at a global scale.

“…The Parahoplitidae Parahoplites is considered a cosmopolitan upper Aptian ammonite (Lehmann et al 2015). The genus unfortunately suffered from extreme taxonomic splitting (Klein and Bogdanova 2013), and homeomorphy has led to erroneous taxonomic interpretations, in particular with the New World faunas (Ovando-Figueroa et al 2018?). Parahoplites should be limited to the various Boreal-Atlantic species, for which the taxonomy needs simplification.…”

The present contribution describes a new rich ammonite material from the Aptian-type area, Vaucluse, France, made accessible by the expansion of the wine cellar of Domaine de Château-Blanc at Roussillon, located at ca. 8 km northwest of Apt. This temporary outcrop exposed a few meters of sandstones and sandy, glauconitic marls, characterising the fifth unit of the Aptian-type series. The ammonite specimens are preserved as crushed, internal moulds with phosphatised shells, and are assigned to the Acanthohoplitidae Egoianiceras angulatum, Egoianiceras lautum, ?Egoianiceras exiquecostatum, and Acanthohoplites sp., together with poorly-preserved Parahoplitidae (Parahoplites sp.). This assemblage is coeval to the Fallot black shale episodes occurring in the nearby Vocontian Basin, and correlates to the uppermost Epicheloniceras martini Zone of Dutour (2005), or the lower Colombiceras tobleri Zone of Dauphin (2002), an age which challenges the younger ammonite-age calibration previously established for the fifth unit.
