Stocksdale Posted September 15, 2014 Share Posted September 15, 2014 I see material from the phosphate mines (Khouribga) dated as Maastrichtian. And the Kem Kem is dated to Cenomanian. So the phosphate mines are considerably younger. Also, is this Kem Kem area where all the Spinosaurus teeth on eBay are originating from or is there also another location? Somewhere, something incredible is waiting to be known.–Carl Sagan Link to comment Share on other sites More sharing options...
Troodon Posted September 15, 2014 Share Posted September 15, 2014 My understanding is that the Khouribga phosphate mines date from the late Cretaceous to Eocene. I would guess most of the Spino teeth you see are from the Kem Kem beds since that is the early Cenomanian exposure that contains Spino remains. There are different exposures in Niger and Algeria that produce Spino teeth. Link to comment Share on other sites More sharing options...
