I'd like to know the species of these sharks teeth. Especially the bigger one. :] hope for help and thanks. More pics and info below.

Hi mosasaurs lovers, I looked around on different american fossils web sites , and I found, is nowhere a description or list about different species of Mosasaurs from Morocco . So I'll try humbly to fix it . Feel free to correct me if you see something wrong. The Moroccan phosphate history began in 1921 , Moroccan phosphate mines operate three layers of phosphates . Level 1 : Ypresian phosphate bed Level 2 : Thanetian phosphate bed Level 3 : Maestrichian phosphate bed Level 4 : Maestrichian grey phosphate at Sidi-Chenan quarry, ben guerir and youssoufia Level 5 : Maestrichian, grey phosphate,white bones: ben guerir and youssoufia level 6: Maestrichian, grey phosphate,white bones: ben guerir and youssoufia Most of the material on a market belong to oued zem and sidi -daoui zone; even though you will find them under Khouribga denomination, nothing comes from Khouribga... Of course, mosasaurs belong to the level 3, and 4 different species are studied by scientists of the French Museum of Natural History in Paris . Today the last record of different mosasaurs species is at list 18 and probably 20. (personal opinion ) Listed like below : †Halisaurus. arambourgi .(Bardet, Pereda Suberbiola, Iarochène, Bouya & Amaghzaz, 2005) †Halisaurus.sp not described yet †Halisaurus walkeri .(Lingham-Solier, 1998) ( i used this name temporarily, until one studie about this mosasaur show-up ) †Prognathodon sp Dollo, 1889 †thalassotitan atrox 2022 ex †Prognathodon anceps ex leiodon anceps slender form massive form perhaps sexual dimorphism ( personal opinion ) †Prognathodon solvayi Dollo, 1889 †Prognathodon hudae kaddumi 2009 †Prognathodon. currii (Christiansen & Bonde, 2002) †Eremiasaurus heterodontus , gen. et sp. nov sp ( AR.
