Not exactly sure what this is..I inherited a couple fossils..all I know is it's a fossil..it's very heavy.i thought maybe trillobites. Or a broken tree branch..my ex husband passed away and left me a box of fossil rocks..and this one is a real curious one..any information is helpful.

Was there a set of carving tools with his things? This look like stone carving to me.

Not seeing any identifiable fossils in the first image, and definitely not in the following images.  

Unfortunately, this looks like all carving, at this point.

I agree but that second one is really nice. 

[Rockwood]

From the look of the first one, they may be sort of inspired by the natural features of concretion.

Well all I know is that it is something.im gonna get back ahold of university of Arizona. And let there geology dept. look at it.when I'd spoke with someone they wanted to slice it open.  And I was totally  against that.ill keep everyone posted.thanks for your help.

They may be concretions with possible fossils inside, which would explain why they would want to slice them open, but at least the second one looks like someone was busy carving away at it for hours. Please let us know about the results of the examination at the university.
