Its lower Miocene members show indications of weak coastal upwelling, with fossil assemblages and calcareous-siliceous rocks formed from diatoms and coccolithophorids.

The lower Miocene molasse in the north of the plain was covered by outwash alluvium of the Is�re, whose terraces today still mark the shape of the Valentinois.
13.
As tectonic uplift of central Borneo continued into the lower Miocene, the westernmost portion of the Kutai Basin was inverted above sea level, forming the Upper Kutai Basin.

Family : " Cadurcotherium " rakoveci, whose fragments were found in Ugljevik, Croatia within brown coal, dated to the Upper Oligocene ( or lower Miocene ).
15.
A single species has been identified from the fossil record; " Alepes pin " ( Bannikov, 1985 ), described from the Lower Miocene in eastern Crimean Oblast.

Juan Tavera further narrowed the age of the formation in 1968 and 1979 by proposing a Burdigalian ( Lower Miocene ) age for Navidad, Lincancheo and Rapel which were then the three subunits of Navidad Formation.

The unit represents a period of around 7.5 million years from 24 Ma ( million years before present ) to 17.5 covering, with the Vaqueros Formation, the entirety of the lower Miocene.

The large McLure Formation, of upper Miocene age, forms an impermeable cap beneath which enormous quantities of oil have pooled over millions of years, principally in the Temblor Formation, which is of Middle and Lower Miocene age.
19.
The fossil record for nuthatches is sparse, and in Europe is limited to the extinct " Sitta senogalliensis " from the Lower Miocene in Italy and somewhat later material from France; the family appears to be of relatively recent origin.
20.
In the northern part of the map area, Sespe Formation is overlain by and inter-fingers with the upper Oligocene to lower Miocene Vaqueros Formation that is composed of transitional and marine sandstone, siltstone, and claystone with local sandy coquina beds.
