Dpaul7 Posted June 8, 2018 Share Posted June 8, 2018 Here is a polished Ammonite from Timor. Ceratite type? (I think it is but I am still a newbie at these) Can someone help with an ID? I have a couple more, will wait for a later time to post. Link to comment Share on other sites More sharing options...
Dpaul7 Posted June 8, 2018 Author Share Posted June 8, 2018 Possibly Paralegoceras ? Link to comment Share on other sites More sharing options...
doushantuo Posted June 8, 2018 Share Posted June 8, 2018 Why? (NOT meant in a bad way, Dave, but I think you know that. ) Link to comment Share on other sites More sharing options...
Ludwigia Posted June 8, 2018 Share Posted June 8, 2018 I think you'll just have to leave that one at Ceratite non det. There's no precise stratigraphical information, practically all of the structural indicators on the shell have been sanded and polished away and the inner whorls can't be observed.

andreas Posted June 8, 2018 Share Posted June 8, 2018 Permian ammonoid for sure. Triassic ones do show a different matrix. Though strong sanded and polished I would lean towards Paralegoceras sp. But I would label it with cf. Paralegoceras sp. There are a bunch of similar ammonoids in Metalegoceratidae 2 Link to comment Share on other sites More sharing options...
Dpaul7 Posted June 8, 2018 Author Share Posted June 8, 2018 8 hours ago, doushantuo said: Why? (NOT meant in a bad way, Dave, but I think you know that. ) I had compared the suture lines to two others that were identified that way, that also came from Timor. (I thought that was a way to do it!!! ) Ludwiga - I do see your point! While it is a PRETTY piece, much is lost in the polishing process. Andreas... An elegant solution.

Ludwigia Posted June 8, 2018 Share Posted June 8, 2018 If anyone here knows his Triassic and Permian ammonites, then it's Andreas, so go with it! Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Dpaul7 Posted June 8, 2018 Author Share Posted June 8, 2018 Again, the central detail is polished away... Suture pattern can be seen, however. Link to comment Share on other sites More sharing options...
Dpaul7 Posted June 8, 2018 Author Share Posted June 8, 2018 Here is an interesting file on the Genus (also called Metalegoceras) Go to https://en.wikipedia.org/wiki/Metalegoceras At the bottom of the page find On Paralegoceras sundaicum Haniel and related forms (1933) Link to comment Share on other sites More sharing options...
