Is this a rudist fossil?

I just found this in Medina County Texas.  Glen Rose Formation.  I am pretty sure it is a rudist fossil?  Please let me know what y’all think.  Thank you.

I can't see enough characters to say YES.

Possibly. But as abyssunder pointed out it is a bit lacking in detail. But there are plenty of rudists in the Glen Rose with that approximate shape and it is also fairly typical in it's "poor" preservation for what one would expect.

At first sight, it reminds me of a segment of a hippuritid rudists with the pillars exposed. But when I look closer, I have problems.

I don´t see shell material, but:

Do they occur as steinkerns/imprints/mold/casts?

What species of hippuritid rudists do occur there?

 

And I have a problem with the marked area:

Why the discontinuity? Maybe a second, smaller segment?

I don´t know, of pics from below and above may be of any help, and if they are even possible.

The reason I thought it was a rudist is because I recently posted a fossil that was identified as a rudist.  They line up exactly the same and look a like to me.  Therefore, I am assuming that is is a rudist.  Here are some photos of the other piece that was identified on this forum as a rudist.  Thank you.

Yes, they are! Thanks for showing the other specimen, this is more clearly a partial rudist, but I am not 100% sure, though. But I am not experienced enough with such partial specimens and have no experience with the rudists in your area, of course :headscratch:.

Keep on hunting, maybe more complete specimens may show up!

The Glen Rose Formation is Upper Aptian to Lower Albian, so the possible rudist(s) can't be compared with the Late Cretaceous Campanian rudist, unfortunately.
I'm leaning toward caprinid rudist in a poor preservation, but it's just a guess. :)
