The problematic fossil Jinonicella from the Lower Silurian of Gotland
- 2006

Ingår i: GFF. - 2000-0863. ; 128, s. 39-42
-
Tidskriftsartikel (refereegranskat)abstract
- The minute problematic fossil Jinonicella kolebabai Pokorny 1978 is described from the Lower Silurian (Wenlock, middle Sheinwoodian) of the Nar-I core from southern Gotland. Growth lines indicate that the characteristic tubular snorkel of Jinonicella grew by envelopment of an emargination in the median dorsal aperture and not as a perforation through the dorsal surface of the shell. The direction of shell coiling indicates that Jinonicella kolebabai can not be closely related to scaphopods (?Devonian, Carboniferous-Recent). If it is a mollusc, it may represent an independent adaptation to the infaunal scaphopod mode of life.
