#3 looks like half a walnut, possibly fossilized. Post these in the fossil forum for better results. Go back to forums and scroll way down. Nice Finds!

They are Cretaceous fossils out of the Edwards Limestone. I'd have to look up some, but the small snails are Exogyras and very common here.

Wondering if the #2's are worm casts? Or is that only found in salt water? I got a bunch of fossils at an estate sale that looked simikar. Thought they were rib bones, but the geologist I worked with at the time (what a luxury, right?) said marine worm casts. I'll post pix under fossils (eventually).
