TXV24 Posted January 9, 2018 Share Posted January 9, 2018 Hi, This doesn't appear to be a mammal jaw. Instead I'm fairly certain this is the lower jaw of an amiid (Bowfin) fish. I've collected quite a few from the Eocene/Oligocene of the UK and there's a strong resemblance to your specimen. Amiids lived (and still do) in a wide range of freshwater (and some brackish) environments, which I think matches nicely with some of the depositional environments of the Kem Kem. Hope this helps.

Hunter0811 Posted January 9, 2018 Author Share Posted January 9, 2018 Hmm i believe you but i can't find anything on the internet about it, can you send a few pictures from your bowfish jaw? Also the fish doesn't seem that big to me... i'll send a few more pics of the jaw... Link to comment Share on other sites More sharing options...
fossilized6s Posted January 9, 2018 Share Posted January 9, 2018 I agree, it's not mammalian.

doushantuo Posted January 9, 2018 Share Posted January 9, 2018 If amiid,it might be Calamopleurus.Known from Kem Kem Link to comment Share on other sites More sharing options...
TXV24 Posted January 9, 2018 Share Posted January 9, 2018 @Hunter0811 Bowfins can be pretty big fish, and some older genera and subfamilies could grow much larger than modern species. Here is an image of probably one the best examples I have, although it's slightly beach worn. This is probably the genus Amia, but there are several subfamilies with the Amiidae yours could originate from. There is a genus called Calamopleurus from the lower Cretaceous of Africa which could be a likely candidate for your Kem Kem jaw, but I wouldn't be able to say for certain.

fifbrindacier Posted January 9, 2018 Share Posted January 9, 2018 Seeing that pic of @TXV24's bowfish, i see the resemblance with your specimen, so i'll go with him.
