The last few fieldtrips didn’t deliver a lot of fossils, so now I got time to get started at my backlog of fossil preps from the Lompret quarry. I still have well over 100kg of material to sort and to prep from there. Last weekend while rummaging through a few of those boxes I picked up one that got my interest. A Fragment of a large nodule with a part of a nicely sized Gephuroceratid poking out. After a good look, there were a couple of other fossil fragments visible in there, sadly the matrix was extremely hard. I had to use a grinder and hammer and chisel to get through it, the problem was that apart from the few visible specimens I was grinding in to it blind, so It happened that I grinded through a few fossils that weren’t visible on the outside. But from time to time I was lucky and exposed a few more fossils, including a nice small pyritized Manticoceras. After that I got the specimens out, I used a grinder to go over the matrix and used colour deepener on the fossils, this gives a nice colour contrast between the fossils and the matrix. The fossils visible on the finished piece are: a few Gephurocertids like Manticoceras sp., a little Tornoceratid, a Bactrites sp., a fragment of a nautiloid orthocone and a brachiopod Ryocarhynchus tumidus. The piece is from the late Devonian, Frasnian, Matagne formation near Chimayin Belgium. A goniatite poking out Grinding, chiseling and airscribing... almost done: All cleaned up picture with scale:
