The curly bivalve appears to be Exogyra ponderosa. The mold looks to be a pectinid (scallop), but can't be certain. Both are Cretaceous in age.

The translucent pebble may be gypsum.

That's a pretty creek!

Is that Walnut Creek south of Austin? Used to camp there when I lived in Texas. lots of Exogyra to be found. Great place to look for snakes too!

 

[Neogeo]

Don't know where I got Walnut Creek?? Must be another park I visited in the Hill Country. I meant to say Mckinney Falls State Park?
