Lincolnshire Limestone Formation
geological formation in England
The Lincolnshire Limestone Formation is a geological formation in England, part of the Inferior Oolite Group of the (Bajocian) Middle Jurassic strata of eastern England. It was formed around 170 million years ago, in a shallow, warm sea on the margin of the London Platform and has estuarine beds above and below it. There are two sub-divisions, the Upper and Lower Lincolnshire Limestone.
It is typically about 30 m thick, reaching a maximum of over 40 m in south Lincolnshire. The lower division varies in thickness between 15 m and 21 m and the upper is typically between 10 m and 16 m thick.
The dividing marker is the 'Crossi' bed which is distinguished by the fossils of the brachiopod Acanthothris crossi it contains. The Crossi bed forms the top of the Lower Lincolnshire limestone. The bottom of the Lower Lincolnshire limestone has some of the characteristics of the underlying Lower Estuarine Series, in that it tends to contain more than usual amounts of sand. A stone from this part of the formation which was commercially exploited is the Collyweston stone slate which was used for roofing for several centuries. It is now largely replaced in new work by concrete imitations.
The public source identifies “Lincolnshire Limestone Formation” as geological formation in England. This brief keeps that definition visible, then builds a research path around Lincolnshire, Limestone and Formation.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Lincolnshire Limestone Formation”, the useful work is to connect “geological formation in England” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 1, 2026. The linked authority identifier is Q6551283. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
