RJB Posted January 28, 2017 Share Posted January 28, 2017 While I was at Quartzite I did buy a few things. I found this at a building that sold mostly Morrocan stuff and was told that this came from there, but I don't believe a thing im told by them. I have done some work on this specimen to make it as best I can, but I have no clue as to what Genus, what species, what formation or anything else for that matter? Any help would be great.

abyssunder Posted January 28, 2017 Share Posted January 28, 2017 (edited) Maybe it's a Douvilleiceras sp. ammonite. (Madagascar?) Collignon,1963_Albien.pdf In the back of it (right side) looks to be a Perisphinctes sp.. (Morocco).

RJB Posted January 28, 2017 Author Share Posted January 28, 2017 Thank you abbyssunder. I was told that it was from Morroco, but I also was guessing that it was from Madasgascar? here are some more pics . RB Link to comment Share on other sites More sharing options...
Wrangellian Posted January 28, 2017 Share Posted January 28, 2017 I agree, it does look like a Madagascar Douvilleiceras. The info I got for my specimen is: D. mammilatum, Lower Cret, Ambarimaningian (L. Albian, ~112my) Mitsinjo?, Mahajanga, Madag. (Boeny Region?) Lots of question marks beside this info, so don't bet too much money on it. Would love to go to the Quartzsite thing someday, must be mind-blowing...

Ludwigia Posted January 28, 2017 Share Posted January 28, 2017 +1 for Douvilleiceras. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
abyssunder Posted January 28, 2017 Share Posted January 28, 2017 They are nice specimens, I'm happy to see they are not polished (too much). They are from Madagascar, the preservation patterns are similar to what I have from there.Here is the typical specimen for Perisphinctes from the region (Madagascar), easily polished, with respect: " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Coco Posted January 28, 2017 Share Posted January 28, 2017 Hi, I am not a specialist in ammonites, but when I saw your pics, I said myself "oh ! Doudous !" (for Douvilleiceras). We don't often see these species on the forum and those of the Troyes region (France) are magnificent. We can't find there any more but I would have liked well going over there...

abyssunder Posted January 29, 2017 Share Posted January 29, 2017 ...unfortunately. I don't understand why they make this.
