Hello forum members! With the new Coronavirus raging across the world, I thought it would be nice to start some kind of advent calendar, using my own Squalicorax collection. Everyday I will post one or multiple Squalicorax teeth from one location. Let's see what ends sooner, my collection or the virus outbreak. I will start with the oldest tooth from the Albian substage and end with the teeth from the uppermost substage; the Maastrichtian. The first one is the oldest and also one of the smallest teeth in my collection. Unfortunately it is so sma

Hello all During my fossil hunt yesterday, I found these two shark teeth right next to each other. I assume both are the same species, I just don't know which one. They were found in the region around Mons/Bergen in Belgium, where both Campanian and Maastrichtian seem to occur. I don't know exactly which layer these came out of, since I found them in a collapsed wall. Sharks seem to be quite rare here, so really happy with them. As found: The second tooth: Thanks all for your help.

Recently I acquired a bulk lot of Moroccan shark teeth after doing some reading and a lot of sorting. I have more questions than identifications. To keep it simple I stuck with the “square rooted teeth for the first round. I’ve come up with five categories 1 two cusplets - Serratalamna? 2 multiple cusplets but small - ? 3 two cusplets - Cretolamna? 4 two cusplets and no or very weak transversal groove - Otudus? 5 strongly reduced cusplets - ? If other pictures are useful let me know.

Just returned from my fall collecting trip to South Dakota. Will focus on my finds and I've attached a couple of prior trips to see more of the area, fauna, finds and collecting gear.
