svcgoat Posted January 26, 2023 Share Posted January 26, 2023 I got a big box of unprepped material from the lance formation here are a couple pieces I started cleaning off. First piece Approx 6x5cm Link to comment Share on other sites More sharing options...

rocket Posted January 26, 2023 Share Posted January 26, 2023 good luck! I am curious how it will look like when it´s finished So, I take my coffee, popcorn and wait Link to comment Share on other sites More sharing options...
hadrosauridae Posted January 27, 2023 Share Posted January 27, 2023 Looks like they have a lot of glue and matrix on the surface, so it could be a challenge. Keep us updated on the progress.

Pliosaur Posted January 27, 2023 Share Posted January 27, 2023 Would like to see how it looks after it has been cleaned and prepped! Seems pretty fragmentary but hopefully you'll be able to identify some part of it, good luck! Link to comment Share on other sites More sharing options...
svcgoat Posted January 27, 2023 Author Share Posted January 27, 2023 @Pliosaur How should I remove the glue? I have debonder but I dont want the thing to fall apart. Link to comment Share on other sites More sharing options...
jpc Posted January 28, 2023 Share Posted January 28, 2023 what kind of glue did the collectors use? This is important to know. Most folks use vinac or butvar in the field, which comes off with acetone. If they used cyanoacrylate (superglue) it is much harder to remove, especially if it what is holding the sandstone together. Superglue really bonds well with Lance Fm sandstone and is a pain in the butt to remove. The fact that you mentioned debonder suggests it is superglue. Debonder will work but you must be patient. 1 Link to comment Share on other sites More sharing options...
Pliosaur Posted January 28, 2023 Share Posted January 28, 2023 Agree with @jpc here’s an article that mentions how to remove super glue from fossils if that’s the case, you can also try applying areas with a light cloth to places where there is excessive glue Link to comment Share on other sites More sharing options...
svcgoat Posted January 28, 2023 Author Share Posted January 28, 2023 Ill ask the seller what was used but I do have a debonder from paleobond Link to comment Share on other sites More sharing options...
jpc Posted January 28, 2023 Share Posted January 28, 2023 the seller may not know if they didn't actually collect it. But the debonder should work on both superglue and any acetone based glue. But be careful that you don't completely teak all the bone pieces apart while trying to remove sandstone. Link to comment Share on other sites More sharing options...
Troodon Posted January 28, 2023 Share Posted January 28, 2023 I know too may diggers and collectors that use Paleobond PB002 and Starbond to cover the bones at dig sites. Just adds so much work to the prep side. Good luck Link to comment Share on other sites More sharing options...

Every year I go out and tell myself "I'm not covering everything in PB02 this time, I can do better!" and then I get the fossils uncovered and they are just a mosaic of fractures and I say "Oh snarge, if I dont cover it in PB02, its going to fall apart before I can get it out, much less the ride back home".

I understand but lots of times its a general purpose application. I'm not sure it needed to be used on the OP specimens. I use PB002 on cracks but PB4417 on wider area. It's a field prep that's a lot easier to remove. Link to comment Share on other sites More sharing options...

It must be a dire sitaution for me to use these things in the field. Link to comment Share on other sites More sharing options...

They take longer to set but are sooooo much easier to deal with back in the lab. 1 Link to comment Share on other sites More sharing options...

svcgoat Posted January 28, 2023 Author Share Posted January 28, 2023 Yeah I haven't prepped in the field yet as California is mostly marine but when I go to Montana in June I wonder what I'll use Link to comment Share on other sites More sharing options...

I need to just leave the PB02 in the truck so I quit reaching for it automatically. "There is no shortage of fossils.
