Decapod assemblage from the late Miocene (early-middle Messinian) of the Romagna Apennines nearby Brisighella, Emilia-Romagna (N Italy)

Abstract

An assemblage of axiidean and brachyuran decapods is reported from the late Miocene pre-evaporitic (early-middle Messinian) limestone of Cò di Sasso, nearby Brisighella (Ravenna, Emilia- Romagna), located in Romagna Apennines (NE Italy). Except Monodaeus bortolottii Delle Cave, 1988 (Xanthidae MacLeay, 1838), which is reported here for the first time in Miocene, all the other specimens have been assigned to species previously known in the Italian Miocene (Messinian s.l.), but never reported in this area. The report of Galathea cf. G. weinfurteri Bachmayer, 1950 (Galatheidae Samouelle, 1819) and Medorippe ampla Garassino, De Angeli, Gallo and Pasini, 2004 (Dorippidae MacLeay, 1838) enlarges the stratigraphic range of these Miocene species. This report enlarges our limited knowledge on the composition and distribution of the axiidean, anomuran, and brachyuran decapods during the early-middle Messinian before the evaporitic event in the Mediterranean Basin.

First report of decapod crustaceans from the middle–late Miocene of Valmarecchia, Romagna Apennines (Emilia-Romagna, Italy)

“…No crustacean records were previously reported from these layers, except for a single decapod caridean assigned to Palaemon monsdamarum PaSini & garaSSino, 2018, from the Messinian tripoli of Mondaino (Rimini, Emilia-Romagna) (PaSini & garaSSino 2018). Other previous reports of Miocene decapods from the Romagna Apennines are limited to some anomurans, axiideans, and brachyurans from two localities nearby Brisighella (Ravenna, Emilia-Romagna), which belong to the early-middle Messinian (PaSini et al 2019). Hence, the new report from Valmarecchia outcrops enhances the scarce knowledge on the presence and distribution of crustaceans around the palaeo-Adriatic Gulf during the middle-late Miocene prior to the onset of the Mediterranean Salinity Crisis.…”

New Report of Decapod and Isopod Crustaceans From the Lowermiddle Pleistocene of Montalbano Jonico, Matera (Basilicata, Southern Italy)

“…Recently, this species was also reported from the Early Pleistocene of Poggi Gialli (Sinalunga, Tuscany) byDe Angeli, Garassino & Pasini in Baldanza et al (2017) and from the Pliocene of Faenza (Ravenna, Emilia-Romagna)(Pasini et al 2018). Finally,Pasini et al (2019) reported M. bortolottii specimen from the Miocene of Brisighella (Ravenna, Emilia-Romagna).The report of M. bortolotii from Basilicata attests to its wide palaeogeographic distribution in Italy and its wide stratigraphic range from the Miocene to the Early Pleistocene.…”

Review of brachyuran crabs from the late Miocene (Messinian) of Oran, Algeria

“…Goneplax gulderi was previously reported from the Miocene of Austria (Baden) (Bachmayer, 1953) and Miocene and Pliocene of Italy (Tuscany, Emilia-Romagna) (Pasini et al 2019, 2020). Its first report in North Africa enlarges its palaeobiogeographic range around the Proto-Mediterranean Basin.…”
