| Formation: | Hujialiang | ||||
| 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 | |
