Final answer:
The Mesozoic Era is not older than the Paleozoic Era. It is actually younger than the Paleozoic Era.
Step-by-step explanation:
No, the statement is False. The Mesozoic Era actually follows (is younger than) the Paleozoic Era. The Mesozoic Era is also known as the age of dinosaurs, which lasted from 245 to 65 million years ago. On the other hand, the Paleozoic Era lasted from 544 to 245 million years ago and is characterized by the Cambrian explosion at the beginning and the Permian extinction at the end.
