The Weeks Formation is known among collectors as a treasure trove of unusual trilobites but it has also preserved soft-bodied animals, some of them also being oddball arthropods hard to pin down to genus. This one seems almost ghostly, a spirit still partly present in the material world. At some point in the future, someone is going to be able to put a name on it.
