Fossilized Mushroom?

[Kobe3006]

I found this fossil while I was hunting deer in The Arizona Mountains. It resembles a mushroom but some people on here state mushrooms dont fossilize. Just looking for anwsers thanks.

This is not a mushroom, but rather half of a type of concretion. Nice one!

Maybe some sort of Petrified wood? 

That pattern is certainly interesting looking.

Welcome to the Forum.

 

We need to know where it was found, in what rock layer and how old the rocks are.

Dies a metal knife blade scratch the needle like areas?

Hiya,Kobe .

A rather nice find, and certainly not a mushroomy-toadstooly thingy.

A good guess is that this is a quartz pseudomomorph of a needle-like mineral that grew in a cavity. Original mineral possibilities include: calcite; aragonite and zeolites. Notice the needles vary their orientation from each other. Each needle is straight.

In organic fossils such as wood, corals, bryozoans etc. the adjacent long structures are very parallel to each other and they are not always straight. They can curve from top to bottom.

That is one of the best mushroom fake-outs we have seen on the forum. I can understand why some people would think it was fossil fungi!
