Tortonian Thermal Maximum

Last updated

The Tortonian Thermal Maximum (TTM) was an interval of relatively warm global climate that occurred during the Tortonian stage of the Neogene period.

Contents

Timing

The TTM occurred approximately 10.8 Ma, during the early part of the Tortonian. [1]

Effects

Global mean surface temperature was about 16.4 °C during the TTM. [2] Lake Pannon, the largest lake in Europe, experienced enhanced nutrient inputs that caused blooms of nannoplankton. [3] Potamidids experienced an expansion in their geographic range, with them entering the Paratethys from the proto-Mediterranean. [4]
