Why are today's land mammals so much smaller than prehistoric mammals?

Well, one possibility is due to competition for food. Large animals need much more food than smaller ones to survive. So, in times of food shortage, the large ones will not have enough to eat or will fight each other for what is available and tend to die off faster than the smaller ones which need relatively little to survive. Another possibility: availability of shelter. Large animals have harder times finding shelter during storms, winter freezes, and other natural catastrophes, while smaller animals can hide much more easily.
