Lee Creek Micro Id Needed


John Hamilton

Recommended Posts

I found this 1.5 mm tooth in my LeeCreek matrix yesterday but can't ID it. If you have any suggestions they would be greatly appreciated. I also decided to try my hand at using photo stacking software and I think the results are pretty good for the first time.

Photos look really good. Which stacking software are you using? Is it easy to use?

Thanks Marco. I used CombineZP (freeware) and it was fairly easy to figure out.

John, I am thinking it may be a rather worn Rhincodon.

Looks like my rhincodon tooth, but much more worn.

Guys I would probably agree with your ID but I can't find a single example of rhincodon that has a central formen like this tooth has. So for now it will stay unidentified.

I didn't try to make an id on this tooth earlier because the wear makes any id pretty speculative. That being said, I don't think your tooth is a Rhincodon. It looks like a lot of the enamel is missing by the root. If the enamel was where I think it was on your tooth, the blade angle to the root is not right for a Rhincodon. However I also don't believe the pore you are seeing is a central formen. The basking shark teeth that I have, tend to have root pores. But they can be in many places on the root, especially if the root is worn down. When I first saw your tooth basking shark came to mind. The angle of the blade to the root (based on where I believe the enamel went to), the general nondescript shape of the root, the root pore etc. all made me think basking shark. However there is no way I could say that positively because of the tooth condition. The tooth could be just a cusplet of a tooth although there are reasons why I don't think that is the case either. Below is a basking shark tooth from Maryland. It looks a bit different from those from Bakersfield CA that I have but is one that you could compare your tooth to and make your own decision.

Marco,

Thanks for the reply. I wanted it to be a filter feeder (cetorhinus or megachasma) but as you stated it is just to worn to make a positive ID. I have a few more teeth that I'm unsure of and would like to get your thoughts on them if you have time. I'll PM you some pictures after I finish my lunch.
