It dates to the <a href="/facts/Middle_Jurassic/3XQSmQgU">Middle Jurassic</a>, mid-<a href="/facts/Bathonian/wDyT99az">Bathonian</a> stage. It predominantly consists of <a href="/facts/Oolite/2GNzb4AJ">ooidal</a> <a href="/facts/Grainstone/l7LEocXv">grainstone</a>. The term "Stonesfield Slate" refers to slaty limestone horizons within the formation that during the 18th and 19th centuries were extensively quarried for use in roof tiling within the vicinity of <a href="/facts/Stonesfield/Q9TlB9hP">Stonesfield</a>, <a href="/facts/Oxfordshire/dc4jQkHB">Oxfordshire</a>. Previously these were thought to belong to the <a href="/facts/Sharp%2527s_Hill_Formation/phQXXvPE">Sharp's Hill Formation</a>, but boreholes and shaft sections suggest that at least three horizons within the Taynton Limestone were quarried for the slate. These horizons are well known for producing a diverse set of fossils including those of plants, insects as well as vertebrates, including some of the earliest known mammals, pterosaurs as well as those of first dinosaur ever described, <i><a href="/facts/Megalosaurus/7Jtw1cYc">Megalosaurus</a>.</i>
