Question

use the drop - down menus to match each description to the geologic era it describes
the first birds and flowering plants appeared during this era. this is also when the most well - known dinosaurs lived

mammals, including humans, emerged during this era

at the beginning of this era, animals lived only in water. by the end, some early dinosaurs emerged

Explanation:

• Mesozoic Era: The Mesozoic is known as the "Age of Dinosaurs." Birds (evolved from theropod dinosaurs) and flowering plants (angiosperms) first appeared during this era.
• Cenozoic Era: The Cenozoic is the "Age of Mammals." After the mass - extinction at the end of the Mesozoic (which wiped out non - avian dinosaurs), mammals diversified, and over time, humans (a type of mammal) evolved.
• Paleozoic Era: At the start of the Paleozoic, most animals were aquatic (e.g., trilobites). By the end of the Paleozoic (specifically, the late Triassic, which is sometimes considered the transition to the Mesozoic in terms of some dinosaur evolution), early dinosaurs began to emerge.
