چکیده انگلیسی
A collection of papers, mostly from amongst those presented to an international meeting held in Sherborne, Dorset, UK, at the end of September 2015 is published as a memorial to Professor John H. Callomon, a physical chemist, who gained a worldwide reputation amongst the palaeontological community for his fundamental contributions to sexual dimorphism in Jurassic ammonites and to Jurassic stratigraphy, particularly of the Boreal Realm. He is remembered too for his encouragement of amateur geologists, several of whom have gone on to become internationally recognised palaeontologists themselves and are included amongst the contributors to this volume. The papers in this collection include ideas at the forefront of Jurassic palaeontology and the stratigraphical refinement that is possible with detailed work on ammonite faunas. Thus, it is demonstrated that it is possible to correlate to ammonite zonal level over a distance of some 7500Â km and it is now clear that ammonite biohorizons frequently allow of correlations of significantly shorter periods than 100Â ka.
