In the geologic timescale, the Bashkirian is the age of the Pennsylvanian epoch of the Carboniferous period of the Paleozoic era do Fanerozoic eon that is comprehended between 318 million 100 thousand and 311 million 700 thousand years ago, approximatedly. The Bashkirian age succeeds the Serpukhovian age of the Mississippian epoch of the same period and precedes the Moscovian age of the Pennsylvanian epoch. The geologic time scale is used by geologists and other scientists to describe the timing and relationships between events that have occurred during the history of the Earth. ... A geologic age is a time period on the geologic timescale delimited by major geologic or paleontologic events. ...
