The aim of this paper is to document the ammonite fauna of the upper part of the Late Tithonian collected at the key section of Le Chouet (Drôme, SE France). Emphasis is laid on new and poorly known Ataxioceratidae, Himalayitidae and Neocomitidae from the upper part of the Tithonian. Among the Ataxioceratidae, a new account on the taxonomy and relationship between Paraulacosphinctes Schindewolf and Moravisphinctes Tavera is presented. Regarding the Himalayitidae, the range and content of Micracanthoceras Spath is discussed and two new genera are introduced: Ardesciella gen. nov., for a group of Mediterranean ammonites that is homoeomorphic with the Andean genus Corongoceras Spath, and Pratumidiscus gen. nov. for a specimen that shows morphological similarities with the Boreal genera Riasanites Spath and Riasanella Mitta. Finally, the occurrence of Neocomitidae in the uppermost Tithonian is documented by the presence of the reputedly Berriasian genera Busnardoiceras Tavera and Pseudargentiniceras Spath.
In 1949 the concept of protected geological sites was first established in UK law by Nature Conservancy (NC) as ‘Sites of Special Scientific Interest’ (SSSIs). In 1977 a systematic site selection process - the Geological Conservation Review (GCR) was established by the UK-wide Nature Conservancy Council (NCC) which identified over 3000 features of geological interest nationally (excluding Northern Ireland), including around 275 representing aspects of Jurassic stratigraphy and palaeontology. These GCR sites formed the basis for all subsequent geoconservation SSSI designation including under strengthened legislation in 1981 and 2002. The fragmentation of the NCC in 1991 established separate country conservation bodies in Scotland (Scottish Natural Heritage), Wales (Countryside Council for Wales), and England (English Nature) with a fourth, the Joint Nature Conservation Committee (JNCC) to oversee certain national and international activities. In Northern Ireland, however, nature conservation remained the responsibility of the Environment and Heritage Service of the Department of the Environment. With the establishment of these five separate organisations, policy and practice began to diverge. The consequences of this divergence are discussed with particular reference to its effects on the conservation of sites of Jurassic palaeontological and stratigraphical importance. Recommendations for future conservation strategies and procedures are proposed.

In 1949 the first concept of a protected geological site was introduced into UK law and within a few years the country had a network of such, now known as "Sites of Special Scientific Interest" (SSSIs). This initial law was strengthened in 1981, but in the meantime a systematic site selection process had also been established by the GB-wide Nature Conservancy Council (NCC) known as the Geological Conservation Review. This process led to the identification of over 3000 features of geological interest nationally (excluding Northern Ireland), including around 275 representing aspects of Jurassic stratigraphy and palaeontology. These "GCR" sites formed the basis for all subsequent geoconservation SSSI designation. Site conservation activity by the NCC was on a learning curve in the earlier days with the legal possibilities of the 1981 act being explored and techniques and philosophies being developed. Political moves, however, led to the fragmentation of the NCC in 1991 to established separate country conservation bodies in Scotland, Wales and England with a fourth to co-ordinate certain national and international activities. In Northern Ireland, however, nature conservation remained the responsibility of the Department of the Environment. With the establishment of these five separate organisations, policy and practice inevitably began to diverge. Wales established a regionalised distribution of geological advisors who take responsibility for much site-based casework. In Scotland, a small group of centrally based geologists provides advice, although in practice most casework is carried out by local, ecological, conservation officers. In England, however, a trend established towards the end of the NCC continued, with more and more key decisions being made by a centrally based group of geological advisors, with limited external scientific input. In addition, local, ecological conservation officers have increasingly been expected to not only give day to day advice on the management of geological sites, but also to set conservation objectives and monitor the same sites. These approaches have not only contributed to significant losses of key parts of several protected Jurassic sites and their contained palaeontological heritage, but also to a high level of under-recording of such damage. In October 2006, however, as a new organisation will take over nature conservation administration in England - "Natural England" - and the time is therefore right to rethink such approaches. Several proposed aims and objectives for the future will therefore be presented, which are not only of relevance to the UK as a whole, but also to the rest of Europe. It is ironic that in the 21st century in one of the countries that first established a systematic approach to geological conservation, especially site selection, significant damage to and losses of Jurassic heritage continue to be observed - a re-assessment of conservation strategies is therefore much needed.
