The era known as the "Age of Invertebrates" primarily refers to the Paleozoic Era, particularly the Cambrian and Ordovician periods, when invertebrate life forms flourished and diversified dramatically. During this time, organisms such as trilobites, brachiopods, and mollusks became prominent in marine ecosystems. This period set the foundation for the evolution of more complex life forms, including vertebrates, which began to appear later in the Paleozoic. The dominance of invertebrates continued well into the subsequent periods of the Paleozoic.
The Age of the Invertebrates, also known as the Paleozoic Era, occurred approximately 542-251 million years ago. This era was characterized by the dominance and diversity of invertebrate animals, with significant evolution and diversification of marine life during this time.

The Neolithic Era is also known as the New Stone Age.
The Mesozoic Era is known as the Age of Reptiles.
The age of invertebrates is primarily known as the Paleozoic Era, particularly during the Cambrian period, which began around 541 million years ago. This era saw a significant explosion of marine life, with invertebrates such as trilobites, mollusks, and echinoderms becoming dominant. The fossil record from this time showcases a diverse array of invertebrate species that played crucial roles in early ecosystems.
The Paleozoic Era is also known as the age of ancient life.
The Cenozoic Era. This began 65.5 million years ago.
