DE&i Posted May 27, 2017 Share Posted May 27, 2017 (edited) Name: Petrodus patelliformis (dermal denticles)Age: CarboniferousLocation: Steeplehouse quarry, Wirksworth, Derbyshire, United Kingdom I haven’t got around to separating or giving it my best shot to an i.d. on the associated crinoids as yet, but I thought you would like to see my work in progress. If you would like to view the PDF below it makes for a very interesting read. Steeplehouse quarry p.s. the scale bar is in mm Edited May 27, 2017 by DE&i Wrongly researched as Eocene when in fact Carboniferous Regards.....D&E&i The only certainty with fossil hunting is the uncertainty. https://lnk.bio/Darren.Withers Link to comment Share on other sites More sharing options...
Goldkaiser Posted May 27, 2017 Share Posted May 27, 2017 Hi DE&i, If these are from the same steeplehouse quarry in Derbyshire I know I believe the fossils are actually much older then Eocene in age and are in fact Carboniferous in age. I visited the site quite a bit while I was studying geology last year and the Material looks very similar GK Link to comment Share on other sites More sharing options...
DE&i Posted May 27, 2017 Author Share Posted May 27, 2017 Thank you @Goldkaiser you are indeed correct and to be honest I completely researched the wrong link. So I'll apply my edit now for the record.

DE&i Posted May 27, 2017 Author Share Posted May 27, 2017 Additional information quoted below from the ukfossils.co.uk website which I thought was very informative. " The shark remains are the most interesting aspect of this quarry. The bedding plains of the large slabs are full of dermal tubercles of the shark-like fish, Petrodus patelliformis. These are hard to see and most are worn, but they are 5 to 8mm in size and look a bit like squashed limpets. Tiny teeth from another shark, Anachronistes fordi, can also be found. Remains from both of these sharks are normally rare from the Carboniferous, but are quite common here, suggesting that a shoal of them suffered a mass mortality event.
