Ever wonder how Trex teeth are cleaned?
You probably haven’t, but after thinking about it maybe you are. We use a sand blaster which uses baking soda to remove glue, dirt, and grime to get these teeth to looking their best before either selling them or putting them on display. This tooth had alot of glue on it because it was fragile when it came out of the ground. Cleaning the glue off is much easier than glueing together hundreds of little pieces later.
Cleaning ancient fossils, especially something as magnificent as a T-Rex tooth, is truly a labor of love and a fascinating journey into the past. Beyond just making them look good for display or sale, proper fossil cleaning is crucial for scientific study and long-term preservation. When I first started working with these incredible relics, I quickly learned it's not just about scrubbing, it's about understanding the fossil itself, its matrix, and the best methods to reveal its intricate details without causing damage. While we often use a precise sandblaster with baking soda, as mentioned for removing stubborn glue and dirt, there are so many other techniques a fossil preparator might use. For instance, sometimes a fossil is encased in a very hard rock, requiring mechanical preparation using tools like air scribes or micro-jacks, which are essentially tiny jackhammers that chip away at the matrix. For other fossils, where the surrounding rock is softer, careful use of brushes and dental picks might be enough. Chemical cleaning can also be employed for specific types of matrix, although it requires extreme caution to avoid damaging the fossil itself. Each fossil tells a story, and part of deciphering that story involves using the right cleaning 'key'. One of the biggest challenges, as you saw with the T-Rex tooth that needed the 'glue off this Trex tooth', is dealing with fragile specimens. Often, when these fossils are first unearthed, they are incredibly delicate and might break into many pieces. Paleontologists in the field will apply plaster jackets or consolidants, including various glues, to hold them together for safe transport. Removing this field-applied glue back in the lab can be painstaking. You're not just cleaning dirt; you're meticulously chipping away at a substance designed to hold the fossil together, trying to reveal the natural surface without causing new fractures. It requires steady hands, immense patience, and often, magnification to see the tiny details. Every speck of matrix removed, every bit of glue carefully scraped away, brings you closer to the moment you see the fossil truly come alive, just as it was millions of years ago. It’s incredibly rewarding to be part of bringing these giants back into the light!
