Baculites in Travis County TX, id and prep questions

[rickeclectic]

I found these baculites near a creek in central Texas. They seem to be in pretty rough shape so hard to identify, but any help appreciated. One of them does show a suture (see closeup) and also when they broke coming out I saw the joint lines. I was able to glue them back together.

I am nervous about doing any real prep work on them as it looks like if I even put a dremel plastic brush on them I will destroy any remaining sutures.

Opinions on id and / or prep?

Yep, baculites.  The good / bad news is that the suture lines are full depth, not just on the surface, but these are mineral infills of the shell, so much closer to being steinkerns than a replacement fossil, so there is nothing left to prep out, its fully exposed.  

 

If you want to improve the appearance, you need glue and sandpaper.  Soak the surface with a super--thin superglue, then polish it with ever increasing grades of wet sanding, up to about 1200 or higher.  Some specimens show the suture pattern really well, some are very week.
