Fossil / Agate ID Very strange petrified fossils? Bone?

[mpwil483]

These were found 30 miles South-East of Prescott, AZ. The Locality is Know for Early Neolithic Mammalian fossils. I didn't make it down to the valley where they were supposed to be, although I started picking up scattered agates and chalcedony. Upon arriving home I lightly cleaned and cut some of my finds. Little did I know, all my finds seemed to be fossils 3-5lbs. The pictures I posted are of 2 clear/amber with white inclusions...found separately. Although they seem to fit together quite well. 4" x 2'' when connected approx weight 2oz- 3oz. I'm lost...and have been reaching these and others I found for months. It appears bone was petrified but looks like some anomaly that its so distinct and the inclusions are white/tan which I Imagine are inorganic and have been replaced with minerals. Which even protrude out of the chalcedony in several areas.

Anyone have any clue what this is?

I think your first impression was correct...chalcedony. I see zero evidence of former life. Nice finds, regardless!
