Above the center there are several good siphons with or without burrows and an abundance of organic casts now holes about 1/2 wide, long and 1/4 to 3/8 inch wide. I have seen these holes in many other sandstones but what opinions they represent I do not know. On smooth surfaces I also saw unmistakable but small gastropod trailings.
