Moozillion Posted September 1, 2018 Share Posted September 1, 2018 (edited) I bought this ammonite many years ago, and I only know it is from Madagascar. I don't know anything else about the particular location within Madagascar or any layer it was found in, etc. So I realize it may not be possible to tell what type it is, but it would be fun to know, if possible. Hmmmm...the program won't let me upload for some reason...the images are 12 MB, 13 and 14. Does that mean I'll have to adjust them to a smaller size file in order to upload? I was trying to have good detail for identification. Edited September 1, 2018 by Moozillion Link to comment Share on other sites More sharing options...

If it still gives You an over size limit, refresh the page. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Moozillion Posted September 1, 2018 Author Share Posted September 1, 2018 OK, one more time... It's about 2 inches by 2.5 inches, if that helps. Link to comment Share on other sites More sharing options...
indominus rex Posted September 1, 2018 Share Posted September 1, 2018 I believe it is a Cleinoceras that has been polished on both sides. Regards, indominus rex 2 Life started in the ocean. And so did my interest in fossils. Link to comment Share on other sites More sharing options...

The sharp and clear bifurcation of every rib seem closer to this than to the separation of ribs in Cleoniceras. You know far more than I, but I'm interested and always trying to learn, so excuse my questioning you.. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

FossilDAWG Posted September 1, 2018 Share Posted September 1, 2018 I agree that the fossil is a perisphinctid. The ribs are not typical of Cleoniceras. Don 1 Link to comment Share on other sites More sharing options...
