Pp. 538–541. {{ISBN|0-520-24209-2}}.</ref> is a geological [[Formation (geology)|formation]] in [[Oxfordshire]] in the [[United Kingdom]]. It dates to the [[Middle Jurassic]], mid-[[Bathonian]] stage.<ref name=benson2009>Benson, R.B.J. (2009).

Previously these were thought to belong to the [[Sharp's Hill Formation]], but boreholes and shaft sections suggest that at least three horizons within the Taynton Limestone were quarried for the slate.<ref>{{Cite journal|last1=Boneham|first1=B.F.W.|last2=Wyatt|first2=R.J.|date=January 1993|title=The stratigraphical position of the Middle Jurassic (Bathonian) Stonesfield Slate of Stonesfield, Oxfordshire, UK|journal=Proceedings of the Geologists' Association|volume=104|issue=2|pages=123–136|doi=10.1016/S0016-7878(08)80014-4|bibcode=1993PrGA..104..123B }}</ref> 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, ''[[Megalosaurus]].''
