One more for today - Timor Ammonite Help request

Recommended Posts

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.

Possibly Paralegoceras ?

Why? (NOT meant in a bad way, Dave, but I think you know that. ^_^)

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.

 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

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!!! :fingerscrossed:)

Ludwiga - I do see your point!  While it is a PRETTY piece, much is lost in the polishing process. 

Andreas... An elegant solution.

If anyone here knows his Triassic and Permian ammonites, then it's Andreas, so go with it!

Again, the central detail is polished away... Suture pattern can be seen, however.
