Paleotemperature record of the Middle Devonian Kacak Episode.

ABSTRACT: The Middle Devonian Epoch, ~ 393-383 million years ago, is known for a peak in diversity and highest latitudinal distribution of coral and stromatoporoid reefs. About 388 million years ago, during the late Eifelian and earliest Givetian, climax conditions were interrupted by the polyphased Kačák Episode, a short-lived period of marine dys-/anoxia associated with climate warming that lasted less than 500 kyr. Reconstruction of the seawater temperature contributes to a better understanding of the climate conditions marine biota were exposed to during the event interval. To date, conodont apatite-based paleotemperatures across the Eifelian-Givetian boundary interval have been published from Belarus, France, Germany and North America (10-36° S paleolatitude). Here we provide new δ¹⁸
