Stratigraphy
Formation:North Horn Member:Joe's Valley
Local section:NHorn Local bed:3
Local order:bottom to top
Stratigraphic resolution:group of beds
Stratigraphy comments: close to the bottom of a reversed magnetic polarity zone interpreted as C28r, but there is no tie point in the section: see Lucas et al. 1997
Lithology and environment
Environment:terrestrial indet.
Taphonomy
Modes of preservation:body
Collection methods and comments
Reason for describing collection:general faunal/floral analysis
Taxonomic list comments:129 m below upper contact of Fm.
see Cifelli et al. 1995 for revised stratigraphic nomenclature
this is usually considered Wagonroad sensu stricto
"Ellipsodon ? sp." of Tomida and Butler 1980 is not mentioned anywhere by Robison; I assume it is a misidentification
