Aurelius Posted February 13, 2017 Share Posted February 13, 2017 Hi there. I got a large lot of teeth from Morocco today. They were mostly shark, but with quite a large number of mosasaur teeth, some ray plates, crocodile teeth, bone material etc. There are several pieces I couldn't identify, but this is the most puzzling one of the lot. It's obviously (to a layperson like me, and keeping in mind that I don't have a clue) a mammalian tooth. As such, it can't be contemporary to the other material. However, it does have lots of matrix jammed into the top of the tooth, which is solid rock and not just sand. It's indistinguishable from the typical phosphate bed matrix, to my eyes. My guess would still be that it's fairly modern, but does anybody have any ideas please? Thanks in advance. Link to comment Share on other sites More sharing options...
jpc Posted February 13, 2017 Share Posted February 13, 2017 looks like a broken sawfish tooth. You are holding the root end in the last picture. 3 Link to comment Share on other sites More sharing options...
Aurelius Posted February 13, 2017 Author Share Posted February 13, 2017 Ahhh yes, thank you - I did say I didn't have a clue! Link to comment Share on other sites More sharing options...
abyssunder Posted February 14, 2017 Share Posted February 14, 2017 I agree. Prior to any comparative determination you have to clean the specimen. Here is a list of possible sclerorynchid sawfishes from Morocco: Ctenopristis nougareti - Maastrichtian/Thanetian (redeposition)Dalpiazia stromeri - MaastrichtianGanopristis leptodon - MaastrichtianOnchopristis numidus - CenomanianSchizorhiza stromeri - MaastrichtianSclerorhynchus palaeocenicus - Paleocene (misident.)Sclerorhynchus sp. - Senonian 1 " 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.

siteseer Posted February 16, 2017 Share Posted February 16, 2017 From the size and the matrix I would say it's Dalpiazia stromeri. 2 Link to comment Share on other sites More sharing options...
