The two were the changes in vertebrates and the evolving of the fish into reptilian form.
The explosion of life in the Cambrian and the mass extinction of the Permian.
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.
The word "noted" is used to indicate that something has been observed, recognized, or acknowledged. For example, "She noted the changes in his behavior" means that she recognized or observed the changes in his behavior.

In two phase locking there are two phases. The first phase is known as Expanding Phase and locks are issued in this phase. No lock is released. Then after change all changes are committed and the second phase starts that is the Shrinking Phase in which all the changes are noted and the locks are released. No locks are issued in this phase
Mesozoic Era and Paleozoic Era.
The first period in the Paleozoic Era was the Cambrian.
The Paleozoic supercontinent ice cap method is a hypothesis that suggests ice caps formed over the supercontinent of Pangaea during the Paleozoic era, leading to global cooling and glaciation. This theory is based on the positioning of landmasses in the Southern Hemisphere during this time, which could have facilitated the buildup of ice sheets and contributed to significant climate changes.
Cenozoic, Paleozoic, and Mesozoic are examples of geological eras that represent distinct time periods in Earth's history. They help classify and organize the vast timeline of Earth's evolutionary and climatic changes. Each era is characterized by specific events, such as the rise of mammals in the Cenozoic era or the dominance of dinosaurs in the Mesozoic era.
The melting of the Paleozoic supercontinent, often referred to as Gondwana, is attributed to several factors, primarily tectonic activity and changes in climate. As continental plates shifted, volcanic activity increased, releasing greenhouse gases that raised global temperatures. Additionally, the breakup of the supercontinent altered ocean currents and climate patterns, further contributing to the melting of ice traps that had accumulated during the late Paleozoic era. This interplay of geological and climatic changes facilitated the transition from glacial to warmer conditions.
