Palaeozoic Shark Tooth

[Peat Burns]

@TNCollector et al. This one seems rather non-descript.  Any ideas?  Helodus? Chomatodus? Psephodus?  I have no idea...  Location and age info in tags.

I'm still new to some of this.  How do I see the tags?

Depending on your device, they should be up under the thread title (Salem fm, Mississippian, Kentucky)

Thanks for the quick response.  Could be a problem with my device.  I don't see the tags.  I use the Chromium browser with the Ubuntu operating system.  Chromium is "Chrome" for Linux.

Could be an issue with the Theme you are using. 
Tags don't show in the classic theme in some browsers. 

See this post.

Thanks, Tim, that did the trick.

Very nice love the colour! Looks like Psephodus or possibly Psammodus.

Sorry for the late response, that is a nice tooth. I have quite a few very similar to it.

 

This appears to be a maxillary tooth of Psammodus lovianus. 

 

For more information on this tooth, see Figure 7a, Plate XIV in the 1883 version of the Geological Survey of Illinois, Volume VII by A. H. Worthen. 

 

The Psammodus genus is well known across the globe, but this particular species was originally described from specimens found in the Burlington Limestone. I have found a few in exposures in both Tennessee and Kentucky, so your tooth can't really be placed with any particular locality that I know of.

Thank you!  Much appreciated.
