Dracarys Posted February 22, 2020 Share Posted February 22, 2020 I have a theropod tooth that has hard rock matrix attached to base. What is the best technique to remove it safely? Thanks in advance. 1 Link to comment Share on other sites More sharing options...
Huntonia Posted February 22, 2020 Share Posted February 22, 2020 Well I'm anything but an expert but here's my advice from what little I know. If you have the patience you could wear down the matrix with a dental pick or a needle of some kind. If you have an air abrasive you could probably use that on very low pressure. However wait for more opinions, mine is off course very inexperienced and quite possible wrong. 1 Link to comment Share on other sites More sharing options...
Troodon Posted February 22, 2020 Share Posted February 22, 2020 What's worked for me is a sharpe Xacto knife and slowly scrap the matrix off. However before I do that I consolidate the tooth especially the base in the root cavity. Then I put solvent on the area I'm working on to try to soften the matrix and glue, if present. Every tooth is different so work slowly. 6 Link to comment Share on other sites More sharing options...

You must be slow and deliberate. Link to comment Share on other sites More sharing options...
caldigger Posted February 24, 2020 Share Posted February 24, 2020 Yes, when it comes to fossils, slow and careful is definately the way to go. Shortcuts usually lead to broken pieces. Link to comment Share on other sites More sharing options...
