Post Oak Creek Sherman Texas Memorial Day pickings

Hi everyone! It’s been a while, but I finally made it back out fossil hunting! Missed being here! 

 

Here are a few of my pickings from Memorial Day on Post Oak Creek in Sherman, Texas. As you can see there are lot of small shark teeth. Most are broken unfortunately. The large piece is a mystery. At first glance it looks similar to the mammoth enamel I have found in the past, but what do you all think??? It has a smooth surface on one side, and a slightly pitted surface on the other. Worn by the elements and/or stained? I can’t tell what this is. There are a few smaller unidentifiable pieces, too. One has what appears to be two triangular shapes on top of each other. No clue! The other small piece has the appearance of (bone?), but the feel of rock. The large black piece? Flint maybe? Any help would be appreciated!

Nice finds.

Hiya shel67...good to see that you're getting a chance to get back out in the 'field' again.

 

Interestingly, that Pleistocene specimen you have there doesn't appear to be from a mammoth or a horse.  It appears to be a partial tooth of an artiodactyl...possibly from a bovid (bison or cow) or one of the large camels that were native to this area during the Pleistocene.  I found a similar fragment in the Clear Creek Local Fauna area near Denton back in the 1980s that I initially thought was mammoth but Dr. Bob Slaughter (deceased) at SMU identified it as Camelops.

This one is very interesting. Almost looks like a weathered dermal denticle top.

Can we see the bottom side of it?

Nice finds! This very much resembles a rhyncholite, i.e. the mineralized portion of the upper jaw from a cephalopod. I am not sure how to distinguish whether it is from a nautiloid, ammonite, or other cephalopod. Rhyncholites are generally uncommon in Texas. Here are a few other rhyncholite specimens from the Late Cretaceous of Texas to compare with:

Can we see some more pictures of this specimen from the sides and the bottom?

Hin,

 

OK with Heteromorph : rhyncholite.

 

Please put numbers to you pics, it is more easy to answer...
