Geobiology of Ancient Ecosystems

Geobiology of Ancient Ecosystems is the interdisciplinary study of the interactions between biological organisms and their geological environments throughout Earth's history, focusing on how these relationships have shaped past ecosystems and influenced the evolution of life. This field combines principles from biology, geology, and paleontology to reconstruct ancient habitats and understand the dynamics of life in different geological contexts.

Key Terms

Fossil
Remains or traces of ancient organisms preserved in rock.

Example: Dinosaur bones are fossils that help us understand prehistoric life.

Paleoecology
The study of ancient ecosystems and their interactions.

Example: Paleoecologists analyze sediment layers to reconstruct past environments.

Biogeochemical Cycle
The movement of elements through biological and geological processes.

Example: The carbon cycle involves the exchange of carbon among the atmosphere, oceans, and living organisms.

Mass Extinction
A significant and rapid decrease in biodiversity on Earth.

Example: The Permian-Triassic extinction event wiped out about 90% of species.

Geological Time Scale
A timeline that organizes Earth's history into different periods.

Example: The Mesozoic era is known as the age of dinosaurs.

Ecosystem
A community of living organisms and their physical environment.

Example: A coral reef is a diverse ecosystem with many species.
