shel67 Posted May 29, 2018 Share Posted May 29, 2018 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!

ynot Posted May 29, 2018 Share Posted May 29, 2018 Equine or bovid, need pictures of the chewing surface. Could be chert or a quartzite type rock, not seeing fossil here. Bone fragment(?) No idea. Nice finds. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough." My Fossil collection - My Mineral collection My favorite thread on TFF.

Fruitbat Posted May 29, 2018 Share Posted May 29, 2018 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. -Joe Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...
abyssunder Posted May 29, 2018 Share Posted May 29, 2018 This one is very interesting. Almost looks like a weathered dermal denticle top. Can we see the bottom side of it?

Heteromorph Posted May 29, 2018 Share Posted May 29, 2018 5 hours ago, ynot said: 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: FOSSIL COLLECTING REPORT December, 2011. Page 258. Waco Getaway. Down a few posts. Can we see some more pictures of this specimen from the sides and the bottom? Link to comment Share on other sites More sharing options...
Coco Posted May 30, 2018 Share Posted May 30, 2018 Hin, OK with Heteromorph : rhyncholite. Please put numbers to you pics, it is more easy to answer...
