StoneAgeQuarry Posted November 23, 2019 Share Posted November 23, 2019 I recently acquired a collection of assorted rocks and minerals. Many of these specimens are from the 70's, 80's and 90's ( am in the US). In this group there is two ammonite in matrix specimens. I believe they are Russian due to them being pyritized. I am having a difficult time finding info about what species and what value these specimens may have. I go to the Tucson show every year and I don't often see ammonites like this. I was told to come here to find the experts! Thank you for your time, I look forward to posting more now that I am a member StoneAgeQuarry Link to comment Share on other sites More sharing options...
StoneAgeQuarry Posted November 23, 2019 Author Share Posted November 23, 2019 Here is the second specimen. Thick guys. All of these have pretty opalescent Nacre If I need to post better photos I can do that. First (Above post) Single ammonite in matrix is 55mm tall x 45mm width x 14mm in thickness at the thickest part. Second (Bellow post) ammonites in matrix are (Left one first, Right one second) 47mm tall x 45mm width x 35mm in thickness 45mm tall x 34mm width x 32mm in thickness Thanks, StoneAgeQuarry Link to comment Share on other sites More sharing options...
caldigger Posted November 23, 2019 Share Posted November 23, 2019 The first one appears to be Quenstedtoceras, can't help you for the second. 1 Link to comment Share on other sites More sharing options...
RuMert Posted November 23, 2019 Share Posted November 23, 2019 The first one is probably Amoeboceras (abundant in Oxfordian-Kimmeridgian), the second possibly - Rondiceras (Callovian). Not garanteed though:) 1 My sites & reports Link to comment Share on other sites More sharing options...
StoneAgeQuarry Posted November 26, 2019 Author Share Posted November 26, 2019 Thank you for the input guys! Does anyone have any idea what the value could be? I haven't had anyone offer to buy them on here so they must not be super collectible. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted November 26, 2019 Share Posted November 26, 2019 Hello, and a very warm welcome to TFF from Morocco. I'm sure many members would be delighted to have these rather beautiful ammonites in their collections. But we cannot give valuations on the forum. They'll be worth whatever someone is willing to pay for them. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
jpc Posted November 26, 2019 Share Posted November 26, 2019 for values, try looking them up for sale on the interwebs. That'll give you a good idea. We can only give good IDs. : ) Link to comment Share on other sites More sharing options...
