Since Pangea was prior the Ice Age, how were the global sea levels?

They were higher than they are today because there was no ice
This was the case after the asteroid too all throughout the Paleocene to Eocene earth was much warmer
then during the Eocene-Oligocene transition Antarctica began freezing over after the formation of the Drake Passage created the South Atlantic Current and sea levels began to fall, earth also began cooling and so glaciers in southeastern Greenland began to appear
During the Oligocene and Miocene Antarctica was mostly a tundra climate with there still being some tree cover around the coasts
then ice age happened after the Pliocene and turned Antarctica into a barren wasteland
