fossilsonwheels posted a topic in Member Fossil Trades Bulletin BoardI have small amounts of micro matrix that I’d be willing to trade. My preference would be to trade both to one person for ease of shipping. Old Church Formation, Oligocene Virginia I had separated some matrix before searching any of it specifically to trade some and rethought it after I found a Pristiophorus rostral lol I decided to not search it though as the intent was to give somebody else a chance to have fun searching. It is very productive matrix. I can see a couple of shark teeth in there. Among the possible shark teeth are Notorynchus, Squatina, Carcharias, Alop
I recently acquired some matrix via trade from @will stevenson. This matrix is from Hallencourt France. Just the second time we gotten to go through the entire process of breaking down matrix to a searchable form. I am still in the process of breaking it down and only have searched probably less than 20%. I wanted to begin the post now as I had a few minutes to write. The material is Early Campanian in age and from the North of France. Unlike my first experience breaking matrix down which was from a location with no publication, there is a publication. Sharks from the Late Cretace
This tiny 2mm tooth has me absolutely stumped. It is from Hallencourt France so Campanian in age. There is nothing that matches up well in the publication. My first thought was perhaps a posterior Chiloscyllium or something along those lines but none of the Chiloscyllium in my collection have striations or some faint ridges nor do any in the paper. This tooth does. Perhaps a juvenile? The root doesn’t look Lamniformes. Doesn’t look Carcharhiniformes so I’m not seeing Scyliorhinus. My other thought was possibly a juvenile Heterodontus. I have and have seen some weird Bullhead
MarcoSr posted a topic in Fossil Hunting TripsSome of my fossil hunting trips take place at home breaking down and looking through matrix obtained from collectors worldwide. This matrix came from the Cretaceous (Campanian) of Hallencourt France. Most of the nicer specimens that I found in this matrix were in the 1.5mm to 4 or 5mm size range. Almost all of the larger teeth were damaged (missing roots, broken root lobes, crown damage). The matrix is a very hard chalk which requires a pick ax or jack hammer to get the matrix from the formation which adds to the tooth damage. I am posting below pictures of a small number of the nicer and more
