A Beauty of a Spinosaurid Tooth

Recommended Posts

Runner64

The coolest colored tooth is this Tyrannosaur tooth (cf. Tyrannosaurus rex) from the Javelina Formation. Is blue!

Love the dendrites in the micro fissures!

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.

Nice color, looks like root etching created that hue.

Wow, I love the etching on that tooth! There can't be many out there with a blue hue.

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.

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

It'll be interesting to see in the end whether these teeth are chalked up to being "residual" denticulated Spino teeth, or something different.

 

Here's the best angle I could get to catch the light on this tooth's serrations:

Nice but with the lack of skulls with teeth not sure we will ever get a definitive  answer.

Very special tooth, not only because of the dendrites.

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?

You know about as much as I do.  Never seen anything published on root etching but I'm assuming it's what you said,  acidity.

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?

 

Beautiful tooth! 

 

My most colourful has to be this baryonyx tooth. Including a photo from the previous owner on their high quality camera

Now that's a beautiful looking (and rare) tooth!

 

The pallet is very similar to mine. High-five for the colourful Spinosauridae! :ighappy:
