Description
Channelaxinus ? sp.
Fig. 9D–E
Material examinedITALY – Emilia-Romagna • 1 spec.; Caselle A; NRM Mo 204840 (L = 20 mm).
DescriptionModerately inflated shell; umbones elevated, small, pointed, prosogyrate; posterior sulcus very close to posterodorsal margin, deep, bordered by sharp ridge; two faint, posterodorsal ridges.
RemarksWith 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 rangeMiddle Miocene, northern Italy.
