Devonica

Devonica is a term that has been used in various contexts, but it most commonly refers to the Devonian period of geological time. This period, which spanned from approximately 419.2 to 358.9 million years ago, is a significant chapter in Earth's history. It is characterized by major developments in the evolution of life.

During the Devonian, terrestrial plants began to diversify and spread, forming the first forests. This colonization of land by flora had a profound impact on the planet's atmosphere and geology. Simultaneously, marine life flourished. Jawed fishes, often referred to as the "Age of Fishes," became dominant, with a wide array of new forms appearing. Ammonoids, a group of marine mollusks, also became abundant.

The name "Devonian" itself originates from Devonshire, England, where rocks from this period were first extensively studied. Geologists use the study of Devonian strata to understand past environments, climates, and the evolutionary pathways of life. The end of the Devonian period was marked by a significant extinction event, though its precise causes and extent are still subjects of scientific research.
