Strange looking fossil from Arizona

Hello fellow hunters

 

Many thanks to the responses for my last post which allowed me to ID a fossil rock as Stramatolite and not tule root.

 

I found this marine looking fossil about one month ago in the Golden Shores area of Mohave Valley AZ where marine fossils are abundant.

 

This rock is 6 inches by 4 inches and 1-2 inches thick. It weighs about 1-2 pounds.

 

I cannot find any images online to help ID it?  Any help is greatly appreciated.P6140187.thumb.JPG.54ccff9739345ba84b4b39a01d0df412.JPG

I'm not seeing anything fossily about this item - looks like a water worn piece of dolostone or limestone, maybe with some nodules in it?

Seems to be geologic in nature, to me.

The lighter middle nodules I would say stromatolite again, but the layering is absent. For this I'm gonna say a large old concretion with a newer clay concretion attached.
