NoahW24 Posted October 5, 2021 Share Posted October 5, 2021 Hi all! I’ve got this heavily weathered Ceraurus, and I’m trying to figure out if it’s best to leave the critter in the rugged natural state or if more of him might be buried: any pointers on determining this? Trying to think twice and dremel once to avoid mistakes… Thanks! Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted October 5, 2021 Share Posted October 5, 2021 (edited) Looks terrifyingly fragile to me. I'd be too scared to touch it, myself, but others will know more. @Kane? @Malcolmt?

Kane Posted October 5, 2021 Share Posted October 5, 2021 With that much shell seemingly missing, I would leave it be. Also, cheirurids like this one will get ruined fast if using a Dremel; these require careful abrasion at low PSI. Any Ceraurus I prep is done with baking soda, 20 PSI at the highest, and as low as 7 for finer details around the pygidial, genal, and pleural spines (which are the thinnest shelled). 4 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Very good to know about shell thickness here- I did not know about the variations on the different segments!

Kane Posted October 5, 2021 Share Posted October 5, 2021 I personally would not even risk a hand prep on these critters. I see a crack running across the cephalon that might best be stabilized, as well as some of those thin layers just beneath the trilobite that seem to want to pop off. 4 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Malcolmt Posted October 5, 2021 Share Posted October 5, 2021 This one will not get a whole lot better even with professional help. I would just keep it as is. 1 1 Link to comment Share on other sites More sharing options...
