Lee Creek Carcharhinus

[sixgill pete]

Okay I have 2 small Carcharhinus teeth from Lee Creek here. The first I am sure is Carcharhinus macloti. The shoulders have multiple cusplets and the blade is non-serrated. On the labial side of the tooth the enamel stops at the root.  

 

                   

 

The second tooth has multiple cusplets on the shoulders and on the labial side the enamel is rolled up on the root, as in falciformis. However  falciformis has a serrated main blade, and the blade on this tooth is also non-serrate. Is this also C. macloti, with "extra" enamel? Or possibly a juvenile C. falciformis with undeveloped serrations?

I wish I could help. I just wanted to comment that I have not seen teeth like these before and I find them interesting.

Both teeth look like C. macloti to me.  The shoulders of the second tooth don't match C. falciformis.  See examples of extant C. falciformis below:

The second tooth looks like it may have been swallowed and somewhat eroded by stomach acid.

Thanks Marco, your pics of the C. falciformis show the tooth is definitely not that. I think C. macloti is correct. 

 

Ron, woul that have caused the "extra" enamel? Maybe eroded the root to uncover it?
