| - The fossil, holotype TPII 2000-09-29, was donated to science by an anonymous benefactor. It is part of the collection of Thanksgiving Point Institute, Inc. and displayed in the North American Museum of Ancient Life at Lehi, Utah. It includes an incomplete skull and mandible (lower jaws) and much of the postcranial skeleton, i.e. the parts behind the head. The skull of Tanycolagreus is less well known than its postcranial anatomy, and only the following elements have been found: left nasal, left lacrimal, left premaxilla and one premaxillary tooth, left postorbital, left quadratojugal, incomplete left squamosal, right quadrate, right splenial, left articular, and two cheek teeth. A paratype has been assigned to the species: specimen AMNH 587 consisting of an incomplete hand also collected from Bone Cabin Quarry and originally in 1903 by Henry Fairfield Osborn referred to Ornitholestes hermanni.[3] Two other fossils have been referred to Tanycolagreus: UUVP 2999, a premaxilla, originally in 1974 referred to Stokesosaurus clevelandi,[4] from the Cleveland-Lloyd Quarry of Utah; and USNM 5737, a pair of distal pubes from Colorado earlier in 1920 by Charles Whitney Gilmore referred to Coelurus.[5] These specimens are from the later Brushy Basin Member.[2] Tanycolagreus is present in stratigraphic zone 2 of the Morrison. Remains possibly referrable to Stokesosaurus have been recovered from stratigraphic zone 5 of the Morrison Formation.[6] A life restoration of Tanycolagreus is also on display at the North American Museum of Ancient Life, where it is portrayed as preying upon a small ornithischian dinosaur, Othnielia rex.
