Post Oak Creek November 2020

[flyingpenut]

Here are some finds from two trips in early November. Several ptychodus with one nice large one, a ton of shark teeth shards, a couple pieces of mammal enamel, and some unknowns. Im posting the shark teeth first and then will post the pictures of some of the others. Let me know what you think. Anyone know the species of the teeth in picture 1? I was specifically wondering about number 3 from the first picture. Pictures 6-10 are closeups.

Haven't been in awhile. No recent floods and heavy crowds have been discouraging, especially after a 5-hour drive from Houston. You did pretty well, under the circumstances. Creek needs a good wash.

Thanks. Im with you on that. A little bad weather might be just what the creek needs.

Great finds! 

 

first pic:

1. Squalicorax sp. (falcatus?) - probably one of the best I've seen from there

2. Scapanorhynchus sp. (raphiodon?)

3. Cretodus crassidens - cusplet, from a big one (from pics 6,7,8), 9 is different, a goblin cusplet

4. Scapanorhynchus sp. (texanus?)

5. Squalicorax sp.

6. Squalicorax sp. (falcatus?)

7. Scapanorhynchus texanus

 

second pic:

1. Ptychodus mortoni - very jealous, would like to see that one closer too

2. Ptychodus sp. (whipplei?) - more pics for better id

3. Ptychodus whipplei

Here are closeups of the other oddities I promised. Item 1 is a mammal tooth but no idea what kind. I have a close up of the chewing surface in picture B. I see several of item 2 around the river but didn't know if they were geological or common bivalves or something like that. That close up is picture C. I also see item 3 frequently and cant figure out if the perfectly round hole in these rocks are natural or man made. Does anyone know? Item 4 is just a bunch of chunkosaurus or possibly modern bone but figured I would give a closeup in picture D. Items 5 are two small similar items. See pictures E and F for the closeup of the structure pattern. No enamel so not a shark but I didn't know if a fish or reptile tooth would have that type of surface pattern or if it was just a small piece of broken bone. Item 6 looks to be petrified wood. Item 7 baculite?

Thanks you very much for the IDs. Here are the close ups of the first two Ptychodus. Ptychodus 4 and 5 have worn surface grooves so probably not able to ID.
