Texas - Ivory or fossilized wood?

[johnnyvaldez7.jv]

I've had this with a bunch of unusual rocks I have cause I believed it to be fossilized wood. And it still may be, but I saw other post of Ivory pieces found and Schreger lines...and I thought this might qualify. The lines are throughout l each layer. I don't know anything about Texas fossilized wood and the trees from then...perhaps someone who does know Ivory and Schreger lines can tell me if this is that. It's a 3.5 inch piece.

Howdy!

Can we see some pictures of the ends? That's the place you want to look for Shreger lines. Also where in Texas did you find it? Is from the Southeast? That area has a TON of Eocene petrified wood especially near College Station and Houston.

Here are the ends with some side views...and yes...I'm southwest of Houston.  I don't really see any lines on the ends...maybe there's some faintly...so if that's the place to look then it could definitely be wood and I'm cool with that.  But...I have a question.  You know how a river can smooth and wear down bones smooth on the edges....I found a bunch of fossilized bone that way. Could it do so to ivory as well or does that stay intact and identifiable regardless? And I'm gonna look into Eocene petrified wood locally...had no idea. Thanks!

I'm not seeing any Schreger lines.

Shreger lines look like lots of little crosses and I'm not seeing any. Here have a look. 

But yeah, petrified wood from what I've been told is the Eocene Yegua formation is really common in that area. It comes from near college Station and is carried down on the Brazos River. It's very easy to find river tumbled specimens on gravel bars where you can also occasionally find Pleistocene Vertebrate remains. Most of the petrified wood is Oak, and some Legume. But Palm wood is also well known to be found and if you're really REALLY lucky, snakewood. But you'll probably find a bunch of fossils ivory before you see any snakewood. That stuff is the Texas petrified wood equivalent of Dakotaraptor.

This looks like one of the the very heavily petrified/silicified pieces of wood I find from time to time.  They have almost a ring to them if you tap them with anything metal.

Yeah it sure does ring like that.  I have a box full of unusual rocks so I thought I'd ask about this one.  I'm glad this forum is here...lots of smart folks to give answers to the things I'm clueless about.  But I'm learning. Plus the reference photos are outstanding that help me to learn.
