Llocene epoch

2. Which organisms lived during the Cenozoic
era? sc.7.E.6.4
A trilobites
B saber-toothed cats
Opterosaurs
D plesiosaurs

Answer 1

During the Cenozoic era, also known as the age of mammals, creatures like saber-toothed cats were present. Trilobites, pterosaurs, and plesiosaurs lived in earlier geological periods, not the Cenozoic.

Step-by-step explanation:

The organisms that lived during the Cenozoic era, which is often referred to as the age of mammals, include various mammals that evolved to fill many niches after the extinction of the dinosaurs. Notable creatures from this era include the saber-toothed cats, which thrived until their extinction. Trilobites, pterosaurs, and plesiosaurs, on the other hand, were characteristic of earlier eras: Trilobites flourished in the Paleozoic era, whereas pterosaurs and plesiosaurs were dominant in the Mesozoic era. The last ice age of the Quaternary Period of the Cenozoic era led to many extinctions including the wooly mammoth, but by its end approximately 12,000 years ago, Homo sapiens had evolved.

Answer 2

During the Cenozoic era, which began about 65 million years ago and continues into the present, the Earth was dominated by relatively small animals, including mammals, birds, reptiles, and amphibians. Invertebrates, fish, reptiles, and other organisms were essentially of modern types, but mammals, birds, protozoa, and flowering plants still evolved and developed during this era. The Cenozoic era is also known as the "Age of Mammals," and North America's characteristic landscapes began to develop during this time. Common Cenozoic fossils include cat-like carnivores, early horses, and ice age woolly mammoths. Therefore, the organisms that lived during the Cenozoic era include mammals, birds, reptiles, amphibians, invertebrates, fish, protozoa, and flowering plants12345.
