howard_l Posted March 22, 2017 Share Posted March 22, 2017 Looks like a Mesozoic Ammonite Howard_L http://triloman.wix.com/kentucky-fossils Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 22, 2017 Share Posted March 22, 2017 According to this website, Besom Hill is Upper Carboniferous in age. It also notes that goniatites are frequently found there. I think I can see simple sutures on the item, so goniatite sounds correct. Neat finds - those should prep out nicely. Regards, EDIT: This book on Google Books mentions the genus Goniatites reticulatus and Goniatites gibsoni Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

fifbrindacier Posted March 22, 2017 Share Posted March 22, 2017 Goniatite or ammonite, we all agree to say it's a cephalopod, you well see the siphon on the first photo.

Strepsodus Posted March 22, 2017 Share Posted March 22, 2017 Hi. I think that's a Gastrioceras listeri Goniatite. Well done. Daniel Link to comment Share on other sites More sharing options...
TqB Posted March 22, 2017 Share Posted March 22, 2017 I agree with Tim and Daniel, Upper Carboniferous goniatites for sure and they look like Gastrioceras. Tarquin Link to comment Share on other sites More sharing options...
doushantuo Posted March 22, 2017 Share Posted March 22, 2017 might be G listeri(Yeadonian/Langsettian) Link to comment Share on other sites More sharing options...
Strepsodus Posted March 22, 2017 Share Posted March 22, 2017 Hi. Here are some Gastrioceras listeri goniatites which I found at another site. The Listeri marine band can be found at Besom hill so I think your fossil is almost certainly Gastrioceras listeri. Unfortunately they are almost impossible to prep so it would probably be best to leave it as it is. Daniel Link to comment Share on other sites More sharing options...

Daniel Why are they almost impossible to prep? Are they very fragile?

The matrix seems to stick to the shell. Also there are a lot of faults in the concretions which often run through the fossils. Some of the goniatites from the marine band are filled with calcite and others are filled with the same material as the concretion. The concretions which contain goniatites with calcite are usually full of crushed goniatites. Some of them are still fully 3d but the centres of a lot of them are crushed. The goniatites which are filled with the same material as the concretion are usually better preserved but the centres are very hard to prepare. There seems to be 3 main types of concretion in the Marine band- the ones with the goniatites filled with calcite, the ones with goniatites filled with the same material as the concretion and a more sandy type of concretion which contains a lot more well preserved fossils though the concretions are much harder to find.

Strepsodus Posted March 22, 2017 Share Posted March 22, 2017 Hi. I forgot to say some of the concretions contain both goniatites filled with calcite and goniatites filled with the same material as the concretions. Daniel Link to comment Share on other sites More sharing options...
abyssunder Posted March 25, 2017 Share Posted March 25, 2017 It is good to know the presence of dimorphism in Gastrioceras listeri, that's why there are variations in form within the same species. excerpt from R. A. Davis et al. 1996. Mature modifications and sexual dimorphism. Ammonoid Paleobiology. Volume 13 of Topics in Geobiology; Chapter 13.

Ludwigia Posted March 25, 2017 Share Posted March 25, 2017 Looks like you've got a good calcite steinkern there at any rate. Nice find! Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
abyssunder Posted March 25, 2017 Share Posted March 25, 2017 I think this document would be helpful, so, I'll put it here for further reference : E. Hull, J. W. Salter. 1864. The Geology Of The Country Around Oldham, Including Manchester And Its Suburbs. Memoirs Of The Geological Survey Of Great Britain And Of The Museum Of Practical Geology. A lot of fossils, including Goniatites species, are mentioned in this old book; Goniatites listeri - appears in his old name.
