Erosion of the recently uplifted areas produced extensive Conditions on each continent changed somewhat because of these positional changes, however it was an overall increase in aridity through mountain-building that favored the expansion of grasslands. Eurasia also experienced increasing aridification during the Miocene. Since the pioneering works of Sellards (1915a; 1916b), it has long been recognized that the vertebrate fossils of the PBR belong to more than one geologic age. marine turtles and land tortoises also occur.
