drbush Posted April 5, 2020 Share Posted April 5, 2020 Hi friends, I wish you all good health, can you help me with this? I went to Khrase city, Rus formation, Eocene, to the east of Riyadh and found many shark teeth. It was a surface find. can you kindly help me identify the species. 1st one is 15 mm by 16mm , 2nd is 15 by 10 mm, 3rd is 20 by 10 mm. 1 Link to comment Share on other sites More sharing options...
Andy B Posted April 5, 2020 Share Posted April 5, 2020 cool teeth. the only one that looks familiar to my novice eyes is the top right. looks tigershark'ish to me. never hunted the Eocene though. 1 Link to comment Share on other sites More sharing options...

Andy B Posted April 5, 2020 Share Posted April 5, 2020 59 minutes ago, will stevenson said: 1.physolageus segundus 2.abdounia spp? 3abdounia spp? Wouldn't the relatively larger size and significant serrations rule out physolageus segundus? We have these I believe in the Cretaceous of NJ but they are typically too small to find in a pan with 1/4" screen. 1 Link to comment Share on other sites More sharing options...

Notidanodon Posted April 5, 2020 Share Posted April 5, 2020 Actually I revise my statement anyone is welcome to chip in but I think it could be galeocerdo eaglesomi like this one Link to comment Share on other sites More sharing options...
drbush Posted April 6, 2020 Author Share Posted April 6, 2020 sn no 1 is physogaleus contortus. 2. galeocerdo eaglesomi. 3. abdounia sp. is that right? Link to comment Share on other sites More sharing options...
Notidanodon Posted April 6, 2020 Share Posted April 6, 2020 I’m not sure on the abdounua spp but otherwise I think so Link to comment Share on other sites More sharing options...
Al Dente Posted April 6, 2020 Share Posted April 6, 2020 I don't think the last two are Galeocerdo. Galeocerdo should have some serrations extending onto the tip as you can see in Will's example. I have a tooth from the late Eocene of Togo that is similar to these two teeth. I don't have an ID for it. Link to comment Share on other sites More sharing options...

Daniel_63 Posted April 19, 2020 Share Posted April 19, 2020 Rus formation is early eocene, isn't it? Link to comment Share on other sites More sharing options...
