“…Without description or figuration, it remains a nomen nudum. It most probably corresponds to our morphotype C. Metacrinus mazarronensis Roux and Montenat, 1977 is very close to M. berthei. It differs in having ZIP of cryptosymplexies with axial groove.…”

“…However, Astibia et al (2020) had attributed to the genus Metacrinus a few pluricolumnals from the Bartonian of the southwestern Pyrenean basin, which is connected with the northeastern Atlantic area, but this record needs confirmation. The Metacrininae remained in the western Mediterranean until the latest Miocene (Roux and Montenat 1977). The genus Isselicrinus, which appeared in the Upper Cretaceous and was distributed worldwide during the Eocene, was still present in the Miocene from Japan to the Caribbean via Crimea and northern Italy (Klikushin 1992;Donovan and Veltkamp 2001;Oji 1990).…”

“…Outside southeastern France, Miocene stalked crinoids (mainly isocrinids) were reported in the Mediterranean area and the Central Parathetys (Fig. 1): in Corsica at Bonifacio (Locard 1877), in Spain in the Betic Cordilleras (Roux and Montenat 1977), in Algeria (Pomel 1887;Dalloni 1917), in Malta (Cooke 1896), in northern Italy (Michelotti 1847;Noelli 1900;Albus 1931), in Austria in the Vienna basin (Kroh 2003) and in Hungary (Sandor 1983). They were dated to the Burdigalian (SE France, Algeria), Langhian (Corsica, northern Italy, Austria, Hungary, Malta) or Late Miocene (Betic Cordilleras).…”

“…They could be considered as having only an Indo-Pacific heritage (Whittle et al 2018). Nevertheless, Roux and Montenat (1977) had already attributed columnals and a single brachial from the Late Miocene of Spain to the genus Metacrinus.…”

Using recent samplings and specimens from ancient collections, 14 sites and five species of stalked crinoids have been listed in the Miocene of the southern Rhodanian basin (southeastern France). Three species and two genera are new for science: Papacrinus avignonensis n. gen., n sp. (Balanocrininae), Paraconocrinus rhodanicus n. sp. (Rhizocrinidae) and Gastecrinus vinealis n. gen., n. sp. (Incertae sedis). The identification among the Mediterranean Miocene fauna of the genus Metacrinus, now confined to the Indo-Pacific province, was confirmed by the discovery of brachial ossicles attributed to Metacrinus berthei. The richest and most diversified site was exposed during temporal excavations at the Place du Palais des Papes in Avignon. Four out of the five stalked crinoid species were found in this fossil assemblage in which M. berthei predominates. ?Endoxocrinus gastaldii is associated with M. berthei in several sites. Using dissociated ossicles, differences in quantitative and qualitative characters between these two species are deeply analyzed with their taphonomical, taxonomical and paleoecological consequences. Paleoreliefs and valleys, which had been incised during the Burdigalian, channeled currents. They favored stalked crinoid settlement on various substrates during the late Burdigalian—Lower Langhian transgression. Comparison with the extant fauna allows us to estimate the depth range of the biotopes with stalked crinoids from 100 to 250 m. These estimates are in agreement with those deduced from other paleontological studies.
