Unclean Split - I now need to a very fine split to piece together the full fossil.
fossil_fun posted a topic in Fossil Preparation
Hello, I recently found a fully articulated fossil after splitting Altamira shale. However, the break was not even. I now have the fossil in two pieces and want to put them together. However, the bottom portion is not fully exposed but very thin. I need to split it in order to have the fully exposed fossil, but am worried that it will just break into a million pieces if I try. As you can see from the picture, I need the small rock to fully split along the fossil line. Any recommendations on how to approach this?- 6 replies

From the album: Elasmobranchs
I do not own this rare tooth. It is from the collection of paleontologist Joe Cōcke, which he found locally and gladly allowed me to photograph.-

So I'm aiming to visit some of the Altamira Shale (Monterey Formation Shale) exposures in my city and try to find some fossils in fallen shale pieces. However, I simply cannot find a good way to split shale (I also have small rocks of Altamira Shale in my backyard, which could be seen as a sort of "practice"). The shale that I get are usually very hard and compact, as seems to not crack very easily with the materials I have. I don't have a real chisel, but I makeshift them (nail, screws, and screwdrivers). When I use them, it seems to just dig a hole in the area where I'm striking at and creates no cracks. Does anyone who has experience with Monterey Shale know the best way to split a shale like this, preferably clean in half? (It seems that the rocks I'm trying to split are the exact same rocks found in any other part of the Monterey Formation, like Jalama Beach)
