Few fossil I need help with...

[Hat]

Hello. I went on a long hike a few days ago and stumbled upon this in a large Cambrian rock. I believe most of the outcrops in this area are very early Cambrian as I find a lot of Archaeocyathids. Is this structure somehow related to the Archaeocyathids? It's about 6 inches in diameter. I have an average sized hand.

 

 

 

 

Another fossil I'm trying to figure out is this....

 

 

Sorry the pic is a bit dark. I'm thinking maybe it's a priapulid with the bottom section broken off? The probiscus appears retracted on the upper right hand side, and the segmentation of the organism is clear.

 

Thanks.

I also would like to know, are these also parts of Archaeocyathids, or is this something else? They all came from the same area of lower Cambrian rock where I find lots of easily identifiable Archaeocyathids and brachiopods.

 

Thank you.

Also, brightened and flipped you dark pic.

All very cool, must be nice to hike and find this stuff.

Yeah, here's a few more pics from the hike. It's near Silver City NM.

Maybe I need to move to New Mexico, Washington only has igneous rocks on my hikes, so no fossils

TqB is one of the TFF members and Tim was tagging Him to look at Your pieces.

They are strange looking fossils and it will be interesting to see what they are.

Oh. Ok. Cool.

Here's a few images of what I am identifying as Archaeocyathids. I'm fairly sure that's what the are, but I'm only an amateur.

It's how to tag a member - "@" followed by username.

 

I'm not sure about your first two but I'm pretty sure the rest are solitary rugose corals and must be post-Cambrian (Middle Ordovician is the earliest possible).

 

Archaeocyathids can look similar but the central cavity is always empty. The third and fourth photos show complete tabulae (horizontal plates) going across them which archaeocyathids don't have. The septa and dissepiments also look typical of rugose corals.

Your latest three photos are solitary rugose corals too (also known as horn corals).

Interesting.

I think your first two photos may be Chaetetes (a kind of sponge, once thought to be a coral).

Haven't visited in a while...such beautiful country.  I can see the "Kneeling Nun"! 

 

(Cooke's and The Burros should have some ammonites!)
