Biogeography is the study of how plants and animals are distributed around the world and why they live where they do. It helps us understand why certain creatures are found in some places but not others.

noun
Biogeography looks at how factors like climate, land formations, and the movement of continents affect where different species live. It combines ideas from biology, geography, and geology to explain patterns of life on Earth.
For dinosaur scientists, biogeography is super important. It helps them figure out how dinosaurs spread across the world millions of years ago. By studying where dinosaur fossils are found, scientists can piece together how these ancient creatures moved and adapted to different environments over time.
Think of a map showing where all the elephants in the world live today. That’s a bit like what biogeographers do, but they also try to explain why elephants live in those places. For dinosaurs, they use fossil maps to understand where different species lived in the past.
Did you know that some dinosaurs that lived in North America have relatives found in Asia? Biogeography helps explain this! During the time of the dinosaurs, these continents were sometimes connected, allowing dinosaurs to move between them.
How does biogeography help us understand dinosaur evolution? Biogeography shows how dinosaurs spread and changed over time. By looking at where different dinosaur fossils are found, scientists can track how species moved across continents and adapted to new environments. This helps explain how new dinosaur species evolved.
What tools do scientists use in biogeography? Scientists use many tools in biogeography. They study fossils and rocks to understand ancient environments. They use maps to plot where species are found. They also use computer models to simulate how species might have moved or changed over time.
Can biogeography predict where new fossils might be found? Yes! Biogeography can give scientists clues about where to look for new fossils. If they know that certain types of dinosaurs lived in particular environments, they can search for similar environments from the same time period in other parts of the world.
