I found a very nice variety of items while hunting my new favorite creek. I think the formation is Eagle Ford. I found a nice ammonite bed that I"ll start checking after a good rise. I had to leave the 50 lb + ammonite until I can get a boat or raft in there to float it out 2 miles. The old US military button was my favorite find of the day. The button is 1902 or later but still very old and makes you wonder how it ended up there? Two of the shark teeth are pretty big.
