Fossilssk Posted December 16, 2023 Share Posted December 16, 2023 Hi, Can anyone help me with ID of these Moroccan phosphate beds shark teeth? Scale is in CM. Thanks in advance. 2 Link to comment Share on other sites More sharing options...
North Posted December 17, 2023 Share Posted December 17, 2023 To my eyes, left one looks like Cretalamna maroccana. Middle one sand tiger like tooth. Not sure about species, but similar are often sold as Striatolamia macrota. Right one looks like small Otodus obliquus. Im not that great with shark teeth, so if Im wrong please correct. 1 There's no such thing as too many teeth. Link to comment Share on other sites More sharing options...
shark57 Posted December 18, 2023 Share Posted December 18, 2023 I believe the one on the left is Cretalamna appendicula. If the center tooth is Striatolamia, then this tooth is from the same time period (Paleocene or early Eocene). The tooth on the right could be a Cretalamna appendicula anterior tooth. If you had the age of the formation these could be confirmed, the Moroccan stuff can be anywhere from Cretaceous to Eocene. Link to comment Share on other sites More sharing options...

I thought C. appendiculata was more of an US and C. maroccana more like African species? Otherwise I would have placed left one too as appendiculata. (Edit: I might be confusing C. biauriculata in here.) Edited December 18, 2023 by North There's no such thing as too many teeth. Link to comment Share on other sites More sharing options...

Unfortunately, all I know is that it's from phosphate mines region of Morroco. But I believe I found one tooth of S. aschersoni (not in the photo) which should be a cretaceous species, but the teeth could be just a mix from different periods.

shark57 Posted December 23, 2023 Share Posted December 23, 2023 Serratolamna aschersoni is a late Paleocene to early Eocene species. Search here on the forum for it and you will see Eocene specimens. Link to comment Share on other sites More sharing options...
