Fossa

The fossa changed by becoming an omnivore so instead of teeth for just eating meat it has molars for grinding up berries and other plants. The environment became a vast desert surrounded by a much larger ocean than we have today because of polar ice caps and glaciers melting. It is a desert because of climate change and deforestation. There is very little life on Madagascar now other than a few animals and very little amount of people, because of the lack of food and fresh water.
