TX Beach mystery fossil

[LandSeig]

I was off this last Thursday so we decided to make a run down to a local beach that produces fossils and the occasional Paleo artifacts and after these latest storms I figured that we would find something. The tide was all the way out and the weather was perfect, so we walked along looking for fossils and other goodies and my wife finds a nice little piece of soft-shell turtle shell in a gravel pile. We came to a blue clay layer that was down by the water line and a larger than normal rock caught my eye. As a rule we don’t have any rocks down here and right off I noticed that it didn’t look like the oyster reef pieces that are around.
Well I brought it home and started cleaning it up and it started to look like something fairly decent but what exactly I don’t know. I started testing it with various things and I buffed the rounded end down with a grinding disk to get a better look at the layers. First I used vinegar to check for calcium from shells and the white concretions bubbles but the brown enamel looking part did not. So I tried a flame test on the brown part and nothing, it’s definitely fossilized.
So It looks to me like solid layers of fossilized “enamel” that has growth lines and layers of calcium in between. I would like to think it is a part of a tooth but it would be something really big. So hopefully someone will recognize it and let me know thanks

It's petrified wood. My guess would be palmwood. Nice find!

Thanks for the reply, most of the petrified wood I find is in freshwater and is solid, but maybe saltwater affects it differently

Very interesting piece! I have found petrified wood in the mountains around where I live. Never found any on the beaches I have visited (several hundred miles from where I live! Thanks for sharing.

This is so cool looking!! The one part of it reminds me of a chunk of petrified wood I found in Colorado.
