The Cenozoic is just as much the age of savannas, the age of co-dependent flowering plants and insects, and the age of birds. [40] Grasses also played a very important role in this era, shaping the evolution of the birds and mammals that fed on them. One group that diversified significantly in the Cenozoic as well were the snakes.
During the early Cenozoic, after the extinction of the non-bird dinosaurs, mammals underwent an evolutionary diversification, and some bird groups around the world developed a tendency towards gigantism; this included the Gastornithidae, the Dromornithidae, the Palaeognathae, and the Phorusrhacidae.

Phorusrhacids, as they are known by their scientific name, were meat-eating birds that during the Cenozoic Era were at the top of the food chain. They had slender bodies, huge beaks and could run ...
The evolution of birds began in the Jurassic Period, with the earliest birds derived from a clade of theropod dinosaurs named Paraves. [1] Birds are categorized as a biological class, Aves. For more than a century, the small theropod dinosaur Archaeopteryx lithographica from the Late Jurassic period was considered to have been the earliest bird.
A skeleton of the Cenozoic fossil bird Gastornis. Birds evolved from certain feathered theropod dinosaurs, and there is no real dividing line between birds and non-avian dinosaurs except that some of the former survived the Cretaceous–Paleogene extinction event while the latter did not.
Prehistoric birds of the Late Quaternary−Holocene Epoch, in the Quaternary Period of the Cenozoic Era. Pages in category "Late Quaternary prehistoric birds" ...
Gastornis is an extinct genus of large, flightless birds that lived during the mid-Paleocene to mid-Eocene epochs of the Paleogene period. Most fossils have been found in Europe, and possible specimens are known in North America and Asia.
