I've been visiting a little site in the Miocene Burgidalian on and off where you can scratch shark teeth out of the fine sandy conglomerate of the upper marine molasse. They are all tiny, but cute, ranging in size from 6-15mm. They were deposited in a narrow arm of the Tethys ocean at the time when the sea was retreating for the last time out of southern Germany and Switzerland, being forced out by the steadily northward moving African plate which was causing the Alps to raise themeselves up into the heights. I guess it was a spawning ground for little sharks, the larger ones spending most of their time in the open sea to the south. Anyway, I don't know all that much about shark teeth, but I've been studying the various types of Carcharias teeth, which apparently make up the majority of teeth found in these layers. I'm just wondering if they all belong to this genus, or if maybe some other ones are there amongst them, or if at least different species are represented. For this reason, I'm posting some of them here in the hopes that someone in the know can have a look at them and tell me more about them. Perhaps in which part of the jaw they are lodged, or even if the one or the other tooth belongs to a different genus. I'll number the photos for better orientation. Thanks in advance for your help. 1 2 3 4 5 6 7 I was also wondering if the following object is a shell-crusher tooth or if it's just a tiny, shiny pebble. It has a length of 6mm.
