Also known as Defence blocks from the Foster Yeomann 'Torr Works' Quarry, now located at Barton-on-Sea
Where: England, United Kingdom (51.9° N, 2.2° W: paleocoordinates 9.6° S, 0.8° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Clifton Down Limestone Formation, Holkerian (346.7 - 340.0 Ma)
• 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.
