Vball Posted November 1, 2014 Share Posted November 1, 2014 Looking for Help with the IDs for these. Bought these at a Rock and Gem show but they had no info on them. Number 1 is 1 inch at it's widest point. Thanks!!! Vball Link to comment Share on other sites More sharing options...
howard_l Posted November 1, 2014 Share Posted November 1, 2014 I am not very knowledgeable on Mesozoic Ammonites which these appear to be, but for a more exact identification the suture pattern must be observed. The photos you have presented do not present them very well. Also if you know where they were collected, that could help someone who might be more familiar with Mesozoic Ammonites.

tmaier Posted November 1, 2014 Share Posted November 1, 2014 It would be best to have more detailed photos. I don't have any ammonites in my collection, never found any in the field. BUT... I want to try classifying these and see how close I get. The ammonite people will be along later to straighten things out. 1. family Placenticerashttp://www.google.com/images?q=Placenticeras&btnG=Search&hl=en&gbv=12. family Eoderoceratidaehttp://www.google.com/search?q=Eoderoceratidae&btnG=Search&hl=en&gbv=1&tbm=isch3. family Placenticerashttp://www.google.com/images?q=Placenticeras&btnG=Search&hl=en&gbv=14. family Acanthoceratidae, genus Mantellicerashttp://www.google.com/images?q=mantelliceras&btnG=Search&hl=en&gbv=1&nfpr=1 Link to comment Share on other sites More sharing options...
Vball Posted November 1, 2014 Author Share Posted November 1, 2014 Pretty sure these are from the Jurassic. There was a Hildoceras Bifrons from UK in the box if that helps it was the only one with an ID. I'm thinking they are from Charmouth or Whitby area but not sure. They were bought in an estate sale so they were probably collected a while ago. I'm hoping they are common ones. Thanks again, Mike Link to comment Share on other sites More sharing options...
Ludwigia Posted November 1, 2014 Share Posted November 1, 2014 Number 4 looks like Amaltheus to me. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
tmaier Posted November 1, 2014 Share Posted November 1, 2014 Number 4 looks like Amaltheus to me. It does look like that. Notice how thin that genus is. How thin is your specimen? http://www.google.com/images?q=Amaltheus&btnG=Search&hl=en&gbv=1&nfpr=1 http://en.wikipedia.org/wiki/Amaltheus Link to comment Share on other sites More sharing options...
Vball Posted November 2, 2014 Author Share Posted November 2, 2014 1 & 4 are thin 4 has a rim around it & It does look like that Amaltheus. Number 2 looks alot like this Catacoeloceras http://andysfossils.files.wordpress.com/2013/04/cata4_s.jpg Number 3 is thicker. Link to comment Share on other sites More sharing options...
Ludwigia Posted November 2, 2014 Share Posted November 2, 2014 Number 2 looks alot like this Catacoeloceras I agree. 3 might be Tragophylloceras. Looks like we're having to do with the southern Jurassic coast. I can't for the likes of me figure out what number 1 could be, though. Greetings from the Lake of Constance.

TqB Posted November 2, 2014 Share Posted November 2, 2014 No. 3 could be Oxynoticeras, a common pyrite one at Charmouth. Tarquin Link to comment Share on other sites More sharing options...
Ammojoe Posted November 7, 2014 Share Posted November 7, 2014 Location, location, location. It's very difficult to determine the identity of Mesozoic ammonites without knowing the location. The specimens are interesting and a trouble to pinpoint down precisely. I'm currently away at the moment, but will give my two cents worth, without any access to reference material. You certainly don't have any Catacoeloceras, Lytoceras or Amaltheus there. Instead I think some of your specimens are from the Bishop's Cleeve area. The first specimen is tricky, and could be an Oxynoticeras - I am not really sure. Number two should be a Bifericeras from Bishop's Cleeve. Number three I agree with Tarquin, an Oxynoticeras, but probably from the Charmouth area. Number four is most likely another Oxynoticeras from the Bishop's Cleeve area. But it all depends on the location; those would be my initial thoughts though. Kind regards, Joe Link to comment Share on other sites More sharing options...
Ptychodus04 Posted November 7, 2014 Share Posted November 7, 2014 Pretty sure these are from the Jurassic. There was a Hildoceras Bifrons from UK in the box if that helps it was the only one with an ID. I'm thinking they are from Charmouth or Whitby area but not sure. I agree, they look like Jurassic ammonites to me. Probably Oxford Clay from the Peterborough area. I most likely have examples of all of those specimens in my collection (unfortunately they are at home, and I am at work...). I'll take a look. You can also send a PM to Evangelos50. He is a UK collector and is the source of all my Jurassic UK ammonites.

Kosmoceras Posted November 7, 2014 Share Posted November 7, 2014 Probably Oxford Clay from the Peterborough area. There are a number of different formations which contain pyrite ammonites in the UK; without having personally collected at them, how have you come to that conclusion?

Vball Posted November 8, 2014 Author Share Posted November 8, 2014 Thanks for checking these out Guys. I was hoping they would be easy to ID. I didn't realize there were so many pyritized Ammos in the UK. This is why I almost never buy stuff that isn't labeled but I really liked these. If you need any more pics let me know my camera doesn't take very good macro pics but I'll see what I can do. Thanks Again, Mike Link to comment Share on other sites More sharing options...

milou115 Posted November 8, 2014 Share Posted November 8, 2014 Hello ! In my opinion it could also come from France (Aveyron) Toarcian in age 1 Osperleioceras bicarinatum 2 Dactylioceratidae => Catacoeloceras (as said before), or Mucrodactylites ? 3 No idea, Oxynoticeras (Sinemurian could be an idea) but there are also Hlidoceratidae (Toarcian) that could look like this one 4 Amaltheidae ? (as said before) Link to comment Share on other sites More sharing options...

Although I have never personally collected a Tyrannosaurus Rex, I have a general knowledge of what they look like. The ammonites look like some in my collection from the area. It was a suggestion. I pity the person who only trusts knowledge gained from first hand experience.

Regrettably there is a misinterpretation; no offence was intended through my curiosity, just an explanation. What I want to express is that a broad familiarity with the different areas needs to be assessed to come up with a likely location. Unlike a T-Rex, pyrite ammonites are not so well recognisable. I too would pity someone who would only trust personal experience, but there is a limit to what can be achieved without firsthand practice in some cases.

Ptychodus04 Posted November 10, 2014 Share Posted November 10, 2014 Perhaps I am more ignorant of Jurassic ammonites than I thought. My experience on this side of the pond with Cretaceous ammonites has been that they are very specific to the formation they are found in. I look forward to being further educated on this topic.

milou115 Posted November 13, 2014 Share Posted November 13, 2014 Hello !! Number 3 is obviously not a phylloceratid Number 2 : without stratigraphic precisions and further preparation it is impossible to be formal on the species of your Catacoeloceras ! You can check our webpage on these ammonites from Aveyron : http://lithotheque.franceserv.com/region/fiche_localisation.php?etage=Toarcien&departement=12 Enjoy !
