Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: "lower part of the Laogou section... Tungurian Stage of Middle Miocene" and equivalent to MN6 |
Lithology and environment
Primary lithology: | gray,yellow sandstone |
Secondary lithology: | red claystone |
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" | |
Environment: | fluvial indet. |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils |
Disassociated minor elements: | many |
Collection methods and comments
Reason for describing collection: | taxonomic analysis |
Collection method comments: "about 500 isolated teeth" of Platybelodon and Gomphotherium, which "are the dominant elements"; Hispanotherium matritense is represented by 20 teeth
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 |
