Clam Shrimp This primitive crustacean is rarer to find than complete trilobites. Found by my gf Paula today (8/19). When alive 380 million years ago,this shell contained a shrimp looking animal. A rare find and large for the species. A pic of a closely related Asmussia (Devonian) shows the anatomy with eyes and antennae. Paula found the fossil exposed in the shale at the streams edge. She called me over to look at it and she of course thought it was a brachiopod. That's understandable. She found a killer Orthospirifer a week earlier at this same locality. It looks like a brachiopod so you can imagine her confusion when I told her it was a branchiopod Some of you like Paula may have never heard of clam shrimp before. But you may have seen or heard of fairy shrimp (Sea Monkeys) and Triops that are alive today. They are all in the same class - Branchiopoda. Thanks, Mikeymig
