Stratigraphy
Formation:Clifton Down Limestone
Local section:Foster Yeomann Torr Works Quarry
Stratigraphy comments: All specimens are from the large blocks of Carboniferous Limestone comprising the lower part of the sea defence/costal protection works at Barton-on-Sea. The Presence of palaechinid echinoids is regarded as indicative of the Clifton Down Limestone Formation, which is correlated with the Holkerian stage of the Dinantian. A specimen of Melonechinus sp. was collected from the Clifton Down Limestone Formation at the Foster Yeoman Torr Works quarry at Merehead in 1981 by Mr. Simon Cook. Similaryly, Archaeocidaris whatleyensis, is from the Clifton Down Limestone Formation, albeit from the ARC Whatley Quarry, near Frome, Somerset. Trilobites from the Barton blocks broadly confirm this assessment; for example, Cummingella sp. is a genus that ranges through the Dinantian.
Lithology and environment
Primary lithology:shelly/skeletal lithified "limestone"
Includes fossils?Y
Lithology description: Although the limestone is very tough -- the kind that causes a hammer to bounce off when struck and at the saame tiem producing a foetid, sulphurous smell of hydrocarbons -- when it is weathered it produces well-preserved fossils.
Environment:marine indet.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection excludes:some macrofossils
Collection methods:selective quarrying,field collection
Reason for describing collection:taxonomic analysis
Museum repositories:BMNH
Taxonomic list comments:Echinoids, crinoids, corals, bryozoans, trilobites, brachiopods, and gastopods are found in these blocks. Only the echinoderm fauna is listed. Collection is made from large defence blocks (Sea wall) located at Barton-on-Sea, but quarried from the Foster Yeoman Torr Works quarry at Merehead
