Includes fossils?Y
Lithology description: "the fossiliferous sandstone bearing H. matritense underlies the sandstone bearing Platybelodong grangeri [position of other fossils not indicated]. Between the two fossiliferous beds, there is a bed of red clay... [H. matritense bed consists of] fluvial gray-yellowish sandstones with gravel"

Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Disassociated minor elements:many
Collection methods and comments
Reason for describing collection:taxonomic analysis

collector, date of collection, and museum repository not indicated
Taxonomic list comments:some chance that this is the same as the "Hezheng" collection with poor locality data (42257), but the faunal list doesn't match
