What ice age happening during the carboniferous?

During the Carboniferous period, approximately 359 to 299 million years ago, there was no significant ice age comparable to those in later geological periods like the Pleistocene. Instead, the climate was generally warm and humid, leading to the extensive formation of coal swamps. However, towards the end of the Carboniferous, there were signs of glaciation in the Southern Hemisphere, particularly in present-day Gondwana, indicating a cooler climate shift that eventually contributed to the formation of ice sheets.
