Dinobot Posted April 2, 2020 Share Posted April 2, 2020 Hi there I recently purchased a Albertasaurus tooth. A portion is in a matrix and there are some broken off pieces. This would be my first attempt a putting a fossil back together. If you could provide any input on 1. if it would devalue it by doing it, 2. how I should do it, 3. and what tools or glue or putty I should use. If you could dumb down the language for me that would be appreciated, like I said this is my first time! 1 Link to comment Share on other sites More sharing options...
Pterygotus Posted April 2, 2020 Share Posted April 2, 2020 I like to use superglue or cyanoacrylate but some other members may give a better alternative . 2 Link to comment Share on other sites More sharing options...

Ok thanks! And what's the best way to remove the larger portion of the tooth from the matrix? Link to comment Share on other sites More sharing options...
Runner64 Posted April 2, 2020 Share Posted April 2, 2020 If it is a clean break, I have used PaleoBond before and I was happy with the repair outcome. 1 Link to comment Share on other sites More sharing options...

Just wondering where this was found? as Albertosaurus is only found in the Horseshoe Canyon Formation so far. 1 Link to comment Share on other sites More sharing options...
Randyw Posted April 2, 2020 Share Posted April 2, 2020 I also use super glue for my repairs. Thin for tight clean breaks and thick for uglier breaks that don’t match up well. As for cleaning. A sharp tool like a dental pick or sharpened nail should work if matrix not to hard or electric engraver or the like for harder matrix. Oh and no a good repair job shouldn’t devalue it any. 2 Link to comment Share on other sites More sharing options...
Troodon Posted April 2, 2020 Share Posted April 2, 2020 I typically dab a debonder like acetone on the matrix to soak and soften it before I try to remove it. I like using a xacto knife to scrape off the matrix. Another consideration is the application of a consolidant on the tooth before I work on it to avoid any further breakage and seal hair line cracks. Where is the tooth from? 3 Link to comment Share on other sites More sharing options...

Dinosaur man / Troodon I was told hell creek formation by the seller on the auction site? Hmm do you think it is something else then? Link to comment Share on other sites More sharing options...

Hmm do you think it is something else then? If it were Albertosaurus, it should be from Horseshoe Canyon Formation (Campanian) in Alberta. If from Hell Creek Formation, it is either T. rex or Nanotyrannus. Do you have the exact location it was found? (Town, County, State). 2 Link to comment Share on other sites More sharing options...

Hmm do you think it is something else then? Yes see Runner64 comments. When your done the repair we can take another look and it might point us to Rex or Nano. However Need a county where its from preservation looks a bit like Judith River 2 Link to comment Share on other sites More sharing options...
Ptychodus04 Posted April 2, 2020 Share Posted April 2, 2020 As mentioned above, drop a bit of acetone or ethanol on the matrix to soften it up and remove as much as you can with a needle. I use cyanoacrylate for repairs like this. Take your time and dry fit the pieces to be sure you aren't gluing yourself into a corner where you can't get the next piece to fit. 1 Regards, Kris Global Paleo Services, LLC https://globalpaleoservices.com http://instagram.com/globalpaleoservices http://instagram.com/kris.howe Link to comment Share on other sites More sharing options...
Dinobot Posted April 2, 2020 Author Share Posted April 2, 2020 So the seller said he found it in Hill county Montana. I've cleaned it up the best I could with a dental pic and toothbrush, the acetone really helped! I haven'tattached the pieces I can only figure out where one of the piece go so far. What is your thoughts on what it is? 1 Link to comment Share on other sites More sharing options...

dinosaur man Posted April 2, 2020 Share Posted April 2, 2020 This is not part of the Hell Creek Formation and is part of the Judith River Formation. It also looks like a Tyrannosaur but to hard to tell species considering the condition of the tooth (to hard to tell position). Cool tooth! 1 Link to comment Share on other sites More sharing options...
Troodon Posted April 2, 2020 Share Posted April 2, 2020 Hill County is what I expected it's the JudithRiver FM like dinosaur man indicated. So the tooth cannot be described to a genus/species and is an "indeterminate Tyrannosaurid" since none have been described from the JRF.. It's a puzzle or unfortunately might not have all of the pieces to put more together, nice job 2 Link to comment Share on other sites More sharing options...

Somehow I picked up an expensive sport (Ice Hockey) late in life. Beautiful tooth, welcome to prepping. 1 Link to comment Share on other sites More sharing options...
