The paper in the works now, including megainvertebrates and vertebrates but only from this single locality. Off hand I don't know of other vertebrate remains in the Wilson Grove, but wouldn't be surprised that there are some in local museum (CAS, UCMP).
Hey Chuck - there is a handful of other specimens from the Wilson Grove at UCMP, and also that dwarf baleen whale skull figured in your 2004 OFR on the formation. Not Bloomfield Quarry but a separate locality. And there's a cranium of Balaenula sp. and a mandible of Parapontoporia sp. from Trenton, with several dozen additional bits from the River Road locality.
