Omnomosaurus Posted January 14, 2020 Share Posted January 14, 2020 It's nothing particularly exciting, but I just wanted to share what is possibly the prettiest looking Spinosauridae tooth I've ever seen. The enamel patterning on it is gorgeous, and very different to what I've come across on run-of-the-mill Spino teeth before. Both carinae and tip are also beautifully preserved. There is a pretty smooth enamel texture and no fluting, plus it's even sporting an offset, short mesial carina for an extra bit of personality. (51mm) Anyone else want to share their favourite colourful teeth? 10 Link to comment Share on other sites More sharing options...
Runner64 Posted January 14, 2020 Share Posted January 14, 2020 The coolest colored tooth is this Tyrannosaur tooth (cf. Tyrannosaurus rex) from the Javelina Formation. Is blue! Beautiful Spinosauridae by the way! Preserved great detail and color 3 Link to comment Share on other sites More sharing options...
caldigger Posted January 14, 2020 Share Posted January 14, 2020 Love the dendrites in the micro fissures! 1 Link to comment Share on other sites More sharing options...
Troodon Posted January 14, 2020 Share Posted January 14, 2020 Very interesting tooth and those dendrites are special. Any evidence of polishing or finish to bring out that luster? The characteristics with the short carina and some evidence of serrations makes it unusual, it's a nice tooth for your collection. 1 Link to comment Share on other sites More sharing options...

Omnomosaurus Posted January 14, 2020 Author Share Posted January 14, 2020 Thanks, all!

The characteristics with the short carina and some evidence of serrations makes it unusual, it's a nice tooth for your collection. It does look stunning in person and is definitely another oddity to add to the pile. I've looked again with a loope, and can't find any evidence of polishing, only the consolidate that's been applied (doesn't seem as "goopy" as a lot of the stuff used on KK teeth though). The apparent serrations were a shock...I wasn't sure if it was just wrinkled enamel on first viewing, but the enamel itself doesn't seem to have any real wrinkling anywhere on the crown; there is more of a braided texture, if anything.

Troodon Posted January 14, 2020 Share Posted January 14, 2020 We are seeing more and more teeth with this braided carina. They seem to be more defined than the figure in Hendricks features paper but the population stil appears to be very small to draw any conclusions 1 Link to comment Share on other sites More sharing options...

Here's the best angle I could get to catch the light on this tooth's serrations: 3 Link to comment Share on other sites More sharing options...
Troodon Posted January 14, 2020 Share Posted January 14, 2020 Nice but with the lack of skulls with teeth not sure we will ever get a definitive answer. 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted January 14, 2020 Share Posted January 14, 2020 Very special tooth, not only because of the dendrites. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Do you have a chemical explanation for what may cause the changes in color and those root etching patterns? I’m assuming the acidity of a plant root leaves a stain causing the patterns and color?
