mezozoiku

Mezozoiku is the Basque-language term for the Mesozoic era in the geological time scale. Spanning roughly 252 to 66 million years ago, it sits between the Paleozoic and Cenozoic eras and encompasses the Triassic, Jurassic, and Cretaceous periods. The era is characterized by major evolutionary and geological changes, including the diversification of dinosaurs, the appearance of the first groups of modern birds, and the rise of flowering plants (angiosperms). The Mesozoic witnessed the breakup of the supercontinent Pangaea and the reorganization of ocean basins, with sea levels generally high but fluctuating.

In the Triassic, ecosystems recovered after the Permian-Triassic mass extinction; archosaurs and synapsids were prominent, and

In modern usage, Mezozoiku appears in Basque-language geology texts, museums, and educational materials to refer to
