Paleozoic era
The Mesozoic era ended with a massive impact caused by an asteroid hitting Earth, leading to the extinction of the dinosaurs.
When the ice age ended, the land once covered with ice was covered with newly exposed land and water from melting ice sheets. This led to the formation of new landscapes and ecosystems as vegetation began to grow in the previously glaciated areas.
When the ice age ended, the land that was once covered in ice was now covered in vegetation and water. This led to the formation of lakes, rivers, and forests as the glaciers retreated. The land also became suitable for habitation by various species of plants and animals.
The last period when glaciers covered most of the earth was the Pleistocene Epoch, which lasted from about 2.6 million to 11,700 years ago. This era is often referred to as the "Ice Age" due to the extensive ice sheets that existed during this time.
When the ice age ended, land once covered by ice was mostly barren and devoid of vegetation. It took time for plant life to gradually colonize these areas, leading to the development of new ecosystems.
Well nobody does really know yet when that "period of time" was if it even happened.
