Found a little gold mine of Turrilites, Echinoids and bivalves

I've driven by this field for years with a big ravine in the distance and decided to check it out since it wasn't fenced or posted and glad I did. The ravine was a good 30-40 yards long, probably 10ft+ at deep end and around 5ft wide, as I got closer the dirt changed to grey clay mud with little vegetation, the surface was sandy and rocky. First thing I saw was the large Echinoid, then peices of what I thought were ammonites until I found a more intact one, then I thought Turritella but didn't quite fit. Had a heck of a time trying to ID them and finally ran across Turrilites, I think that's what they are. I went in shallow end of ravine to grab a few things and ended up with 10lbs of mud stuck to my feet so anything else was retrieved by reaching over edge of ravine. Couldn't tell what half of it was until I got home and washed them off. So here goes my ID efforts, Hemiaster echinoids,  a Texigryphaea,  the group with clam, and possibly a Trigonia, and what looks like deformed echinoid ?  Not sure about the last 2 tiny ones, some kind of bivalves?  This is the most fossils I've found in one spot and I'm unfamiliar with some so appreciate any help!

Congrats on your discoveries!  I think your IDs are reasonable with a few tweaks.  The echinoids look like Hemiasters.  That is a Texigryphea.  The heteromorphs look more like a Mariella species.  You have a worn Trigonia mold.  Not sure about the large bivalve, but the two smaller ones are Plicatula.  

 

Based on this grouping and your description, you were likely in the Grayson formation, not the Eagle Ford.

The surface geology might be mapped as Eagle Ford, but the "ravine" cut down into the Grayson.

Actually I just looked at map and according to it I was in Woodbine, I just assumed Eagle Ford because I didn't see anything red.
