Well there have been four major ice ages the earliest was around 2.7 to 2.3 billion years ago during the early Proterozoic Eon.
The last ice age ended 100 000 years ago.
The last, and present, ice age started about 2.6 million years ago, shortly after North and South America were joined to each other and preventing warm water from the Pacific from entering the North Atlantic Ocean.
The dragons were driven up to the caves by humans after the last ice age. The ice age had already happened before they were driven up. After the KT event, the earth was almost completely wiped out but only the READ MORE

Well for one thing, it didn’t. The definition of Ice Age is a period of extensive glaciation with brief interglacials between the points of highest glaciation. By that definition we’re are still in the middle of an ice age, a READ MORE
Yes, it is believe that there was a glaciation at the beginning of the ordovician, and posibly one nearing the end. It is generally thought to be a period of tropical temperatures, and high sea levels.
The geo-historic opposite of the Ice Ages (maximum glaciation) would be the periods of higher temperatures such as the Cretaceous Thermal Maximum (65 to 100 million years ago) and the Paleocene-Eocene Thermal Maximum (peaking about 55 million years ago).
