Huntonia Posted December 28, 2019 Share Posted December 28, 2019 I purchased a nice Redlichia Mansuyi trilobite a while ago. Most of the matrix still feels solid and hard however some of it (which feels kind of like clay to me) seems to have dried and is flaking off. Do I need to be worried? Would it be necessary to consolidate the fossil with paraloid or something similar? Link to comment Share on other sites More sharing options...
Pterygotus Posted December 28, 2019 Share Posted December 28, 2019 Hello. If you’re worried about the fossil being destroyed, then I would use Paraloid B72 to coat it in. Link to comment Share on other sites More sharing options...
Huntonia Posted December 28, 2019 Author Share Posted December 28, 2019 That's what I was thinking but I'll have to buy more acetone and it's a bit of a pain to do in the climate I live in. If possible I'd like to avoid doing that. Link to comment Share on other sites More sharing options...
connorp Posted December 28, 2019 Share Posted December 28, 2019 Can I see a picture of the trilobite itself? The mud shales the fossil came from are highly weathered so it's not unusual for the matrix to be very brittle. Link to comment Share on other sites More sharing options...
Huntonia Posted December 28, 2019 Author Share Posted December 28, 2019 Sure thing. All the matrix around the trilobite seems fine it's just a layer on the back that seems to be losing its integrity Link to comment Share on other sites More sharing options...
connorp Posted December 28, 2019 Share Posted December 28, 2019 I don't think anything needs to be done, looks pretty standard for Chengjiang fossils. Link to comment Share on other sites More sharing options...
Huntonia Posted December 28, 2019 Author Share Posted December 28, 2019 Thanks for the help as always. Chinese trilobites are really not my area, maybe should have done a bit more research before buying one! Link to comment Share on other sites More sharing options...

If possible I'd like to avoid doing that. I’ve heard about a thin layer of cyanoacrylate glue being used but never personally tried it. Its apparently harder to remove than paraloid.
