Landscape River Rock Finds

[AggieGrass]

Howdy, 

 

Couple day old member here. I am a Landscape Professional and I see alot of river rock. Lately I've moved to Austin, TX and have noticed alot of petrified wood in the rock materials we use. I'm 99% positive it is all native, locally sourced in the Texas Hill Country. 

 

Anyway I have a few pieces I'm curious to whether it's machine marks or not and a couple pieces I'm not sure if they're just gnarly rocks or not. Petrified wood ID is what brought me here and I found some good info so I signed up. Any information and help is greatly appreciated. Thanks yall!

These two are the pieces I found a couple weeks ago that really got me started looking.

The first one looks like it's a brachiopod, but I'm not sure about the others.

Welcome to the forum. Your first two specimens are an oyster, looks like Exogyra sp. which are common in the Cretaceous deposits of Texas. #3 is a silicate mineral along the lines of chert/agate. This is the same for #6 and #7. #4 looks like an imprint from an orthocone cephalopod to me and 5 and 8 look like petrified wood.

Welcome to the Forum.   

 

I agree with member Thomas.Dodson.

Yeah I am not great at ID'ing marine animals, but at least I tried.

Awesome! thank yall for the help. But I did not do well at describing the pictures. Next I will haha. So 1-3 are the same piece, same for 4, 5 and 8, 9. The others are individual pieces. Also I missed 1. 

 

Look forward to learning from/with yall. Thanks again!

This one looks like banded chert.

Sweet. That's what Mr. Dodson thought too

Welcome from a local.  

 

Indeed, you have an Exogyra, some banded chert, a partial gastropod mold (most of the local chert originates from the Cretaceous Edwards Formation), more chert, a couple of pieces of petrified wood, and the spiral of a gastropod in cross section.
