The Hop 5:

 

1: Isurus retroflexus: A huge mako. By far my largest tooth yet, with a 2” slant height. Smooth cutting edge and cloudy colors on the crown.

 

2: Carcharodon hastalis: Found by my dad. His best tooth from the trip. Absolutely pristine condition and beautiful colors. Very tiny but visible cusps near the root.

 

3: Hemipristis serra: A small but pretty Hemi. Not in perfect condition, but the colors and lines on the crown make it look quite cool.

 

4: Carcharodon hastalis: This White Shark tooth...is a white shark tooth! Very small and worn down, but super cool white/cream color. But clearly not modern.

 

5: Negaprion eurybathrodono: This is my largest Lemon yet, and it’s absolutely stunning. Very nice colors and a sharp tip, which is atypical of a Lemon.

This tooth looks more like Anotodus retroflexus a.k.a. Isurus retroflexus.  Major shark researchers like Herman and Cappetta now consider retroflexus to be a giant Alopiidae, so this species is now considered a giant thresher instead of a mako.  This has not been embraced by the masses of collectors yet.

I had a feeling it wasn't actually desori. Of the large teeth found in Miocene exposures, that was the species it seemed to resemble most, but it certainly seemed atypical. I believe your identification is correct. Because this is my largest tooth, and a nice one at that, I plan on framing it. Do you suggest I label it as Anotodus or Isurus? Thanks!

I agree with Herman and Cappetta, so I would label it " Anotodus retroflexus".  If you aren't sure, you can label it  " Anotodus retroflexus a.k.a. Isurus retroflexus" or keep it as "Isurus retroflexus" if you don't feel the tooth is a giant Alopiidae.  This is an example of why I don't label anything in my collection other than with the time period and site information.  I have seen just too many name changes over the 45 years that I've collected shark teeth.  I got tired of changing labels and I know what everything is.

Woah, wait, what? I missed this! Retroflexus may be a thresher!?!

Herman has been saying for years that retroflexus is a thresher.  Cappetta originally disagreed.  However this is what Cappetta said in 2012 and a plate showing Anotodus retroflexus teeth:

Thanks for that, I can certainly see the resemblance! You learn something new everyday.
