I’m using a “Chicago pneumatic”, a workhorse engraving pen, not built for fossil prep technically, but widely adopted in the past- though now more options exist from a few companies that are more $$ but built for the purpose. We use a range for different tasks! 🦴

3rd thread in my Cyonosaurus behind-the-scenes process:
First cast out of the mold here turned out great! Sometimes the first time I fill a new mold, I’m learning how to work with it & it isn't always a useable cast, but no major defects this time. My son gave a hand demolding🙏
