Diversity in stegosaurian and theropod dinosaurs. 131 Ma First pine trees. 140 Ma Orb-weaver spiders appear. 135 Ma Rise of the angiosperms. Some of these flowering plants bear structures that attract insects and other animals to spread pollen; other angiosperms are pollinated by wind or water. This innovation causes a major burst of animal ...
Researchers believe that fossilized feces and vomit from dinosaurs are shedding light on how the ancient creatures evolved to become dominant on Earth. A recently published study analyzed hundreds ...
