Which Paleozoic invertebrates had become extinct by the end of the Paleozoic?
Trilobites, eurypterids, and blastoids are examples of Paleozoic invertebrates that became extinct by the end of the Paleozoic era. These marine creatures were once diverse and abundant but disappeared due to various environmental changes and extinction events at the end of the era.
Which life forms dominates the early middle and late parts of paleozoic era?
During the early Paleozoic era, marine invertebrates such as trilobites dominated. In the middle Paleozoic, fish and early land plants became more prominent. By the late Paleozoic, amphibians, reptiles, and forests of ferns and seed plants were thriving.
What is one major geologic development during the Paleozoic era?
One major geologic development during the Paleozoic era was the formation and breakup of the supercontinent Pangaea. This event had significant impacts on ocean circulation, climate, and the distribution of landmasses and species.
Which era of geologic history marks a time when life rapidly became more complex when marine life became more diverse and plants first emerged on Earth?
The era that marks a significant increase in the complexity of life, particularly with the diversification of marine life and the emergence of plants on Earth, is the Paleozoic Era. This era began around 541 million years ago with the Cambrian Period, known for the "Cambrian Explosion," when many phyla of marine organisms rapidly evolved. The Paleozoic also saw the first land plants appear, contributing to the complexity of ecosystems.
Why are more fossils found in the paleozoic era than in the precambrian era?
During the Precambrian times, life was mostly limited to single celled organisms. Life that was not single cellular didn't have any hard body part (like teeth, bones, shells, etc.) and so they weren't preserved.
