Is this a fossil?

[Benjaminpb]

Hey guys, I'm new to this site. I'm hoping someone can help me identify some fossils I've found here in central Texas recently.

I've done some research and found out that the fossils here are mostly from the Cretaceous period. I was walking around in a creek bed today with two of my kids and we found some things that look like old bones. I'm obviously unsure of what they are and would really appreciate some feedback. Thank's, Ben P.

Welcome to the forum from New York!  Can you take a pic of the ends as well as the opposite side? Also what Is the size of the item?

I'm getting a burrow cast vibe on this one:

Thank's for the warm welcome darctooth! I am actually going to be on vacation in New York in about three weeks.

I'm having trouble posting pics on here but I will continue to try. It's only letting me post one at a time.

Welcome from Texas. 

 

I agree with Fossildude19 (Tim), this looks like a burrow cast (the harder, consolidated remnants of sediment within an ancient marine burrow).  They can be very common in some formations around Central Texas.

+1 for burrow.

Thank's for the prompt feedback everyone!

I have a few more fossils that I'm curious about as well. I'll post them on a new thread soon. Thank's again,Ben P.

Here's the rest of what we found today.

Any thoughts?

I think those with pinched ends are likely coprolites. They look very similar to coprolites I've examined from the Eagle Ford Formation. The two longer ones look more like burrow casts, but could be coprolites as well. If you lightly touch the tip of your tongue to coprolites from this formation, they should stick. If they don't stick, I think your are looking at burrows casts.

You are coming to New York, in the middle  of February,  and you call it a vacation? I hope you you know how to Ski ! Lol.

And you sound so convincing!

You think I'm kidding?

Hhhhhmmmmm, lick fossilized poop for science?.....I'll do it!

This also works for fossilized bone provided it is not siliceous. Let me know if you have stickage!

What county were they found in?

[Benjaminpb]

Round Rock Tx.

williamson county

Round Rock covers several different geologic formations, ranging from Lower to Upper Cretaceous.  It's hard to see details in your images, but most of what I can see appears to be either burrow casts or possible parts of rudists from west of I-35.

Hmmm, stickage not stinkage.....

I recently told lady friend to tap small round specimens she had picked up on her teeth. If it clicks it was at least stoney. If it does not click throw it away.....

They were rabbit pellets.

Her response was, what's a rabbit pellet?

You can guess what her reaction to my answer was!!!!

@bone2stone that's the best story i have heard in a long time, made my morning.

[Plax]

top center rock I think I see a steinkern of an oyster or trigonia

[Benjaminpb]

That's funny bone2stone! You should have told her they were milk duds.

Anyways.....I really appreciate everyone's input. I'm not sure that there's a general consensus yet though. Here's a few more pictures, hopefully they help. I'm very curious about the cracking at the ends. My daughter found the large rock with what appears to be one "growing" in it.

I agree with JohnJ. Some of them (if not all) share the internal mold morphology of rudists, especially of Caprinids. Here are some examples.

@bone2stone that is the best one yet!
