Caption: A fossil specimen of Anthracoceras paucilobum Phillips. A fossil ammonite. (Mollusca, Cephalopoda, Ammonoidea.) Kingshill No. 3 Shaft (1949), Lanarkshire, Scotland.
Description: Anthracoceras is a goniatite characteristic of marine bands of the Middle Coal Measures of Britain. British Geological Survey Biostratigraphy Collection number GSE 11150. It has a globose very involute and compressed shell ornamented with a delicate transverse striae. This specimen is from strata associated with the Carboniferous, Upper Limestone Group, Calmy Limestone. The early ammonoids of Devonian and Carboniferous times were characterized by having simple 'goniatitic' sutures of simple zig-zags. While goniatites survived into the Permian they were replaced during the Triassic to the Cretaceous with forms with complex sutures.
