Explanation:
Cave lions, sabre-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths were prevailing species of the Quaternary period. Without the dinosaurs, plant life had an opportunity to flourish during the Cenozoic era.
The Quaternary period was dominated by cave lions, saber-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths. Plant life had a chance to thrive during the Cenozoic era without the dinosaurs.
From the Cenozoic period nearly 66 million years ago to the present day, life is considered recent.
Plants and animals look the one most like they do today during this time period.
The Cenozoic Era is divided into even smaller periods known as Epochs, so there will be even more guideposts in this Era.
Because of the extinction of many groups of giant mammals during the Cenozoic era, smaller species were able to thrive and diversify because their predators no longer existed.
Thus, big cats, saber-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths monopolized the Quaternary period.
Plant life had a chance to thrive without the dinosaurs during the Cenozoic era.
