Need help identifying fossils

[Kristi Waters]

Hi I apologize in advance if I’m in the wrong place as I’m seeking any information regarding several fossils I have stumbled across in Arizona near the Colorado River.

 

These fossils however are located high on top of a mountain. I sent photos a while back to the Grand Canyon paleontologist who identified them as being from the Cambrian Period.

 

I have since found many other interesting fossils with one looking much like the claw of a prehistoric animal.

Many of my fossils appear to be rocks that look like they are filled with cement which I’m assuming would be ash from a volcano. If anyone has any information it would be greatly appreciated.

 

Thank you for your time.

Hi,

 

You are in the right place to identify your specimens. That said, it is advisable not to put so many photos on a single post. In addition, it would be nice to number your photos as for example A1, A2, B1 etc, A representing a specimen, B another etc...

 

Arizona is a large state, a more precise location would help with identification as it helps determine stratification, and therefore potential fossils. Measurements in cm or inches also help with good identification.

 

I can’t distinguish anything that would tell me that you have one or more fossils, but others will arrive and complete my answer.

I'm seeing what might be fossilized inclusions, maybe coral for instance, in photos number 10, 11, 13, 14, 15 & 16, but we would need the information that Coco is asking for in order to get more definite.

Your rocks look like limestone with chert. Pool acid should cause the limestone to fizz and a metal blade will scratch the limestone. The chert will not fizz in acid or be scratched with a metal blade. 
 

Assuming all rocks are from the same formation; they are probably from the Permian Kaibab Limestone. I think that I see the common sponge, Actinocoelia maeandrina and a branching bryozoan.

Welcome to the forum! As Coco said, size and numbering your items can help tremendously with getting your items identified. 

That said, this photo also looks to me to show fossil material, but marine fossils aren't my area of expertise, so I would defer to others to confirm or rule out an ID.
