Barstow Formation

Type of Preservation: 
impression
General notes: 
Later Middle Miocene (EBERTLY & STANLEY 1978) in Mojave Desert, California, USA. Calcareous nodules contain small silicified arthropods (crustaceans, arachnids and insects, mainly immatures biting midges and diving beetles) of excellent preservation state (SEIPLE 1983 and references therein)

Dominican amber

Type of Preservation: 
fossil resin
General notes: 
The fossilised resin of a leguminose tree Hymenaea, of the Early to Middle Miocene age, is been collecting in various sites of the Dominican Republic (ITURRALDE & MACPHEE 1996). Dominican arthropods are extremely numerous and diverse: the collection kept in the Smithsonian Institution (Washington DC, USA) comprises some 5,000 pieces, about 3,000 of them being studied more carefully have yielded more then 9,000 fossils (Rasnitsyn unpublished). The general appearance of the fauna is that of the average Central American tropical forest, except for a few exotic elements, and most species and some genera being extinct (POINAR 1992a, and references therein).

Merit-Pila

Type of Preservation: 
fossil resin
General notes: 
This resin was found in Merit- Pila coal-pit in central Sarawak, Malaysia. The coal belongs to the Nylau Formation (Early-Middle Miocene). Seven insect orders (mainly dipterans and hymenopterans), as well as spiders, mites, diplopods and chilopods have been recorded (HILMER et al. 1992).

Shanwang

Type of Preservation: 
impression
General notes: 
400 insect species belonging to 84 families and 12 orders have been described from the Middle Miocene diatomites of the Shanwang Formation in 22 km East of Linqu, Shandong Province, China (ZHANG 1989, ZHANG et al. 1994).

Stavropol

Synonyms: 
Stavropol
Type of Preservation: 
impression
General notes: 
Numerous and diverse insects are found in marls and calcified mudstone nodules of the Middle Miocene, exposed in Vishnevaya Balka (Valley) next to Senghileevskoye Lake near Stavropol, as well as at Temnolesskaya near Stavropol (Central North Caucasus, southern Russia). According GONTSHAROVA (1989: 65), these deposits are Late (latest in Vishnevaya) Tchokrakian (East Paratethian regional stage of the Neogene). Insects indicate savannah-like landscape for the lower part of the section and subtropical forests for the upper one (BECKERMIGDISOVA 1964, 1967, DLUSSKY 1981b).
