Abstract
A new specimen of the Coleoidea from the Charmouth Mudstone Formation of the Dorset Coast has been identified as Loligosepia bucklandi (Voltz, 1840). The specimen includes the gladius and jaw fragments, which represent one of few records of its kind, but the head area, arms, hooks and suckers are not discernible. It can be favourably compared to other L. bucklandi fossils in the Natural History Museum in London and the J.F. Jackson Collection in the National Museum Wales in Cardiff. The range of L. bucklandi is determined to be from the Turneri Zone, Brooki Subzone to the Obtusum Zone, Stellare Subzone of the lower Sinemurian, with the new specimen stratigraphically a little older than the precisely located specimens in the J.F. Jackson Collection.
期刊介绍：
The policy of the Geological Quarterly is to publish significant contributions of information and geological insight relevant to an international readership. The journal has been issued since 1957 at the Polish Geological Institute - National Research Institute and, at present, is the leading Earth sciences journal in Poland. All aspects of Earth and related sciences, and universal and broad regional rather than locally oriented topics are covered.
The journal is intended to be an international forum for the exchange of information and ideas, particularly on important geological topics of Central Europe.
