Very nice, one I dont have in my collection. What are the roundish objects to the side of the echinoid?----Tom

I have a handful now and all from the same local and layer. But sometimes I found three and the next handful of trips zero.

Oh, almost forgot. The round things are really big foramnifera. Orbitolina texana. They are one-celled animals and an index fossil for the Glen Rose Formation. They occur sometimes in huge thick beds. At this site there is a bed more than a meter thick of them. Literally gazillions.
