Abstract
ABSTRACT The oldest known specimens of the enigmatic mollusc Jinonicella kolebabai Pokorný, 1978 are redescribed from Middle Ordovician strata of Ukraine and Belarus. The phosphatic internal moulds preserve imprints of growth lines, hitherto only documented in Silurian specimens. The persistent distribution of Jinonicella in the Baltoscandian basin of the Russian Platform suggests that this was the centre of origin of this taxon. During the Silurian, Jinonicella inhabited Siberia and Laurentia, and the smaller European terranes of Bohemia and the Carnic Alps. In the Devonian, Jinonicella is reported from Laurentia, Bohemia and the Rhenish Massif.
期刊介绍：
GFF is the journal of the Geological Society of Sweden. It is an international scientific journal that publishes papers in English covering the whole field of geology and palaeontology, i.e. petrology, mineralogy, stratigraphy, systematic palaeontology, palaeogeography, historical geology and Quaternary geology. Systematic descriptions of fossils, minerals and rocks are an important part of GFF''s publishing record. Papers on regional or local geology should deal with Balto-Scandian or Northern European geology, or with geologically related areas. Papers on geophysics, geochemistry, biogeochemistry, climatology and hydrology should have a geological context. Descriptions of new methods (analytical, instrumental or numerical), should be relevant to the broad scope of the journal. Review articles are welcome, and may be solicited occasionally. Thematic issues are also possible.
