Texas mysteries from the North Sulfer river (teeth, fish?, more)

[Kenna in Texas]

Good morning! After a few visits to the North Sulfer River in north Texas, I am asking for help id-ing 14 finds (plus one from Williamson county, Texas). A few teeth and bone, and objects that are just intriguing. There are multiple views in each image - please let me know if an additional image/info is helpful. Many thanks in advance for any responses!

I'm seeing lots of rocks and concretions/nodules. Not seeing any fossils here, though. 

Wait for other opinions. though.

I agree, other than 5, which looks like bone to me.

Thank you for the quick replies. I anticipated that #'s 4,8,10 and 15 may well be rocks. For the others, though, I wonder if my photography skill failed me, but will wait for a few more replies if incoming. Appreciate it!

mystery #1 is definitely not a fish, unfortunately. but #5, as the others have said, is bone. its really weathered, so its difficult to say what element it represents.

I agree with my fellow forum members, 5 is the only fossil, bone and its not really diagnostic enough to proffer an ID.

Thanks, Petalodus and Advantage, for taking a look. With more poking around I agree that #1 is no fish. 

 

For everyone, I’ll point out what I am seeing in #1 and offer a comparison I just found.

 

#1 has an opening in the bone in the upper left portion. (Yes, the one side of #1 is clearly bone when held in the hand.)  The attached close-up shows that this is not a random opening or damage but an eye socket with a protective brow ridge. The next photo is a close up of the bottom edge of #1, showing teeth, and revealing that edge to be a maxilla.

 

Now for the comparison: This is an amphibian from New Mexico, Stenokranio boldi             . (Photo taken from research paper, courtesy of Fischer Jan). Compare the highlighted portion with #1.

 

I am not saying that #1 is clearly a Stenokranio boldi. But I do think they may be close cousins. 

 

Anyhoo, I do appreciate all the responses!

Unfortunately, your one has no bone texture or indication of being a fossil skull.
