Stratigraphy
Formation:Panaca
Stratigraphic resolution:group of beds
Stratigraphy comments: said to be Blancan I and between 4.95 and 4.50 based on biochronology (lower bound) and paleomag (upper bound) by Mead and Taylor 2005
Lithology and environment
Primary lithology: siltstone
Secondary lithology: sandstone
Lithology description: formation is "approximately 427 m... horizontally stratified siltstones, sandstones, and mudstones, with occasional small artesian spring-formed lacustrine deposits" (Mead and Taylor 2005)
Environment:fluvial-lacustrine indet.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils,mesofossils
Collection methods and comments
Collection methods:selective quarrying
Reason for describing collection:general faunal/floral analysis
Museum repositories:AMNH
Taxonomic list comments:see Golgotha Watermill Pothole Quarry (Hemphillian)
UALP 8197 is only 10 m NE of Limestone Corner and 1 m higher stratigraphically; both are 1.6 km NE of Panaca
? Teleoceras sp. of Stock 1921 from LACM 3546 is implied to be from low in the section, but this appears to be based on a priori biochronological considerations
