During the Cretaceous period (65 MYA), the Earth's landmasses were further breaking apart. This put evolution on speed, especially in Australia. Why? Many organisms were now allopatric. Many organisms got to experience new climates. Many organisms were now sympatric. Gymnosperm plants were on the rise, and thus provided new niches for animals. Mountains formed, thus influencing species distributions.
