The '''Eyam Limestone''' (formerly known as the '''Cawdor Group''', '''Cawdor Limestone''' or '''Eyam Group''') is a geologic formation in the Peak District, {{wipe|England}}. It preserves fossils dating back to the Viséan stage of the [[Earth:Carboniferous|Carboniferous]] period, and represents a marine environment.<ref name=":0">{{Cite web |title=BGS Lexicon of Named Rock Units - Result Details |url=https://webapps.bgs.ac.uk/lexicon/lexicon.cfm?pub=EYL |access-date=2023-09-01 |website=webapps.bgs.ac.uk}}</ref>

==Depositional environment==
At the time of deposition, Britain was just south of the [[Astronomy:Equator|equator]] (<5° S) and part of the [[Earth:Euramerica|Euramerica]] continent. Study of the growth rings of fossil wood from other localities indicate that the British Isles had a [[Earth:Monsoon|monsoon]]al climate during the early Carboniferous, with tropical rainfall seasonality.<ref>{{Cite journal |last=Falcon-Lang |first=H. J. |date=March 1999 |title=The Early Carboniferous (Courceyan–Arundian) monsoonal climate of the British Isles: evidence from growth rings in fossil woods |url=https://www.researchgate.net/publication/41816712 |journal=Geological Magazine |language=en |volume=136 |issue=2 |pages=177–187 |doi=10.1017/S0016756899002307 |s2cid=130499005 |issn=0016-7568}}</ref> The Eyam Limestone was deposited on an extensive, thick carbonate ramp and platform on the northeast margin of the Widmerpool Gulf (an extensive basin which existed as an area of open water during the time of deposition). [[Earth:Reef|Reef]]s and their associated fore-reef and [[Earth:Lagoon|lagoon]]al environments are represented in the Eyam Limestone, with [[Biology:Crinoid|crinoid]]s dominating the reef and providing habitats for other animals. The presence of photosymbiotic [[Biology:Coral|coral]] and micritic envelopes on some crinoid ossicles indicates the formation was deposited within the [[Earth:Photic zone|photic zone]] in a marine environment of normal salinity. The presence of the xenacanth ''[[Biology:Bransonella|Bransonella]]'' has been suggested to imply freshwater influence as xenacanths live mainly in freshwater habitats, however its presence in other marine formations suggests that ''Bransonella'' was a marine animal unlike its relatives.<ref name=":1">{{Cite journal |last1=Smith |first1=Roy |last2=Martill |first2=David M. |last3=Duffin |first3=Christopher |date=2017-06-01 |title=The shark-beds of the Eyam Limestone Formation (Lower Carboniferous, Viséan) of Steeplehouse Quarry, Wirksworth, Derbyshire, UK |url=https://www.academia.edu/33671880 |journal=Proceedings of the Geologists' Association |volume=128 |issue=3 |pages=374–400 |doi=10.1016/j.pgeola.2017.04.004 |issn=0016-7878}}</ref>

[[Chemistry:Apatite|Apatite]] crystals formed by the recrystallization of phosphatic overgrowths are present on some [[Biology:Conodont|conodont]] elements from the formation. As phosphatogenesis only occurs in the anoxic-oxic boundary while apatite [[Chemistry:Precipitation|precipitation]] occurs in the top few centimeters of the sediment column, this reveals that shallow sediment with low geothermal temperatures and dysoxic conditions were present in the Eyam Limestone.<ref name=":1" /><ref>{{Cite journal |last1=Sanz-López |first1=Javier |last2=Blanco-Ferrera |first2=Silvia |date=2012-10-01 |title=Overgrowths of large authigenic apatite crystals on the surface of conodonts from Cantabrian limestones (Spain) |url=https://doi.org/10.1007/s10347-012-0295-3 |journal=Facies |language=en |volume=58 |issue=4 |pages=707–726 |doi=10.1007/s10347-012-0295-3 |s2cid=140725466 |issn=1612-4820}}</ref>
