| Summary: | Channelaxinus ? sp. Fig. 9D–E Material examined ITALY – Emilia-Romagna • 1 spec.; Caselle A; NRM Mo 204840 (L = 20 mm). Description Moderately inflated shell; umbones elevated, small, pointed, prosogyrate; posterior sulcus very close to posterodorsal margin, deep, bordered by sharp ridge; two faint, posterodorsal ridges. Remarks With its sharp posterior ridge and groove, and the faint, radial posterodorsal ridge, this specimen resembles Channelaxinus sp. from the Middle Miocene Ca’ Cavalmagra seep deposit (Kiel & Taviani 2017: 450, fig. 5), and is hence tentatively place in Channelaxinus. With about 20 mm in length Channelaxinus sp. is notably larger than Thyasira sp. 1 and 2 reported above. Stratigraphic and geographic range Middle Miocene, northern Italy. ... : Published as part of Kiel, Steffen, Sami, Marco & Taviani, Marco, 2023, Mollusks (Gastropoda, Bivalvia) from Miocene cold-seep deposits in northern Italy: revisions and additions, pp. 115-160 in European Journal of Taxonomy 910 on page 142, DOI: 10.5852/ejt.2023.910.2365, http://zenodo.org/record/10350702 ... |
