Chondrichthyian palate

Made a latex cast of this fossil today. Still practicing the technique, so it didn't come out super pretty but it shows what the maxilla would've been like had it not been just an impression in the rock. Especially interesting is the teeth and how you can see that they actually curve inwards, which I didn't notice before. The latex also preserves the fine texture of the fossil cartilage, which I wasn't expecting, unfortunately due to the transparency of the cast you can't really see this in the photo. I want to try experimenting with coloring the latex or ammonium chloride later on to get better images, but so far I'm very satisfied with these results.

This super cool technique was taught to me by @izak_ who seems to have it down to a science with some of his projects, as they look fantastic. 

Terrific @Misha! I have seen this specimen on here a few times and thought it would latex well, nice work

Cast this in black and I think it looks even better, it gets rid of the transparency so here you can see much more detail. I did mess it up a bit and the teeth on this one didn't turn out as good, even though I thought I had a good method down for doing them which involved carefully filling the cavity bottom up with latex with a hypodermic needle. Might be because I didn't stuff them with cotton like last time and they got damaged when taking out the cast, but I'm not 100% sure. Either way, I'm happy with the result and probably won't be making any more casts of this piece
