WebPasserine (perching) birds also evolved, expanding dramatically midway through the era. The first primates appeared early in the Cenozoic. Fossil evidence suggests that the first hominins (human ancestors) appeared roughly six million years ago, and modern humans arose some 300,000 years ago. WebIn the Mesozoic Era (about 252 million to 66 million years ago), the most important of the synapsids were the archosaurs, or “ruling reptiles,” and the therapsids were, in general, small active carnivores. greenlife cannabis calgary
