triászjúra

Triászjúra is a paleontological term referring to the geological period encompassing the Late Triassic and the Early Jurassic epochs. This time span, roughly from 237 to 174 million years ago, marks a significant transition in Earth's history, particularly in the evolution of life. It witnessed the breakup of the supercontinent Pangaea, leading to significant geographical and climatic changes.

During the Triassic-Jurassic boundary, there was a major extinction event, the Triassic-Jurassic extinction, which wiped out a significant portion of marine and terrestrial life. This event paved the way for the diversification and dominance of new groups of organisms in the Jurassic period. Among the most notable developments was the rise of dinosaurs, which began to flourish and occupy various ecological niches. Pterosaurs, the first flying vertebrates, also appeared during this time.

In the oceans, marine reptiles like ichthyosaurs and plesiosaurs became prominent predators. The plant life also underwent changes, with gymnosperms becoming more widespread. The Triászjúra period is crucial for understanding the evolutionary pathways that led to the Mesozoic Era's characteristic fauna and flora, setting the stage for the "Age of Dinosaurs." The geological formations from this era provide valuable insights into the paleogeography and environmental conditions of the time.
