MarcoSr Posted December 28, 2017 Share Posted December 28, 2017 I want to thank Alexandre @Quriosity for matrix from the Miocene of France (Miocene, Langhian Age, lower "dark" horizon, Loupian Quarry, France) and the Cretaceous of the Congo (Cretaceous, Maastrichtian,Tchivoula Quarry, near Hinda, Congo). The matrix was very fine. It was processed and ready to search. I spent almost a year and a half almost exclusively with the terrestrial Eocene/Oligocene matrix from my sons' ranch in Nebraska. It was nice to get back to marine matrix especially from two sites that I hadn't searched before. In the Miocene matrix from France (This was a very small sample size of a very fine matrix) I found a number of bony fish teeth, 7 Dasyatis teeth, 3 shark teeth, and two dermal denticles. Here is a picture of everything in a 1.75” diameter gem jar cup. Here are pictures of the 3 shark teeth. They are pretty small around .4 to .5 mm. Here is a picture of one of the Dasyatis teeth which were all under 1 mm. In the Cretaceous matrix from the Congo I found a good number of bony fish teeth, a good number of ray and sawfish teeth, and at least one shark tooth. Because of the matrix size I really didn’t expect to find shark teeth. I did recognize a number of species from the Maastrichtian of Morocco. However I did find several species that looked different. At some point I’ll take a lot more pictures of the ray and sawfish teeth. Here is a picture of the bony fish teeth in a 1.75” diameter gem jar cup. Here is a picture of the ray and sawfish teeth in a 1.75” diameter gem jar cup. Here is a picture of the shark tooth and a few odd specimens in a 1.75” diameter gem jar cup. Here is a picture of the 2 mm shark tooth. I’m not sure if this is a shark tooth with a damaged root or maybe a ray tooth, something like Cretomanta.

ynot Posted December 29, 2017 Share Posted December 29, 2017 Nice! You come up with such unique matrixes to search and find some nice pieces in most of the matrix.

Shark teeth around .4 mm are tough to take pictures of because it is very difficult to position specimens that small without damaging them.

At some point I hope to move to South Dakota and spend lots of time looking for micros in formations like the Lance Formation and Hell Creek Formation. I've only looked at a small amount of matrix from these formations so far. Marco Sr. "Any day that you can fossil hunt is a great day."
