found a rather large slab of what seems to be many different creatures and possibly plant life

Oooo cool! I love a multi speciman plate!

Your plate is served Randy..

@ChrisSarahRox, one of the questions is, are there more of the kind you posted initially? If so, could you give a rough estimate? Thank you!

Nice assortment of marine fossils, btw .

Thank you very much! To answer your question, yes. I have others very similar to the initial photos but they are a bit smaller and less right angles if you will.

Any chance of providing a overall shoot of the specimens? Just to see the variation. Thanks!

Of course I can, gladly. I will put a photo shoot together and have them ready by sunrise.

My apologies for the delay , here are the photos of some of the rocks found very near the initial photos.

Thank you very much for the additional pics!

Not as fossiliferous as the first one, but some of them look quite similar.

Have you tried a scratch test and an acid test on the compact, dark grey parts?

Try to scratch the dark, "glassy" looking parts with a steel nail or a knife blade - what happens?

Put a small drop of vinegar or diluted hydrochloric acid on a dark grey part - what happens?

I'm going to tag @PFOOLEY on this...

 

I've talked with Dr. Lucas about this area before, when we were discussing Lower Cretaceous rock exposures in NM. In the Puerco watershed, the rocks jump from Jurassic in age to Upper Cretaceous in age and that begged the question of "where is the Lower Cretaceous?". One area where the Lower Cretaceous is exposed is Hidalgo County. @ChrisSarahRox, based on the fossils you have shown, I would guess that your Turitella sp. hash is Lower Cretaceous (Aptian/Albian) and the brachiopods and crinoid stems are Mississippian in age. There are also Permian and Devonian outcrops in the area...quite a lot of diversity in the uplifted rocks of those mountains.

This is awesome to read and I could not be more appreciative for the time spent on photos I have shared and many questions I've asked. I hope to share many more with this forum and it would be safe to assume many more questions will follow.

My apologies for my delayed response, I will do as you have instructed and post the results tomorrow afternoon.
