Have you ever wondered where your home would have been millions of years ago?
A new online tool developed by an international team of Earth scientists can now give you that answer.
Led by Professor Douwe van Hinsbergen from Utrecht University, the team has created a website called Paleolatitude.org.
It allows anyone to type in a location and see what latitude it occupied in the distant past, going back as far as 320 million years ago when all continents were joined together in the supercontinent Pangea.
The research behind this tool was published in PLOS One.
This tool is based on a highly detailed scientific model known as the Utrecht Paleogeography Model.
It helps scientists reconstruct how Earth’s surface has changed over time, including the movement of continents, the formation of mountains, and even the disappearance of entire tectonic plates.
Compared to earlier models, this one is much more precise and includes smaller tectonic plates and even “lost continents” that no longer exist today.
Understanding where a place was located in the past is important because latitude strongly influences climate. Areas near the equator receive more direct sunlight and tend to be warmer, while regions closer to the poles are cooler.
When scientists study ancient rocks, fossils, or climates, they need to know where those materials were located at the time they formed—not where they are today. This is because Earth’s tectonic plates are constantly moving, sometimes carrying land across vast distances over millions of years.
For example, researchers studying fossils in the Netherlands found that 245 million years ago, the region had a climate similar to today’s Persian Gulf, with deserts and tropical seas. This wasn’t because the entire planet was hotter, but because the land that is now the Netherlands was once located much closer to the equator.
To build their model, scientists followed two main steps. First, they reconstructed how tectonic plates moved over time by studying folded rocks in mountain ranges. These rocks were originally flat but became bent and twisted as plates collided. By “unfolding” them, scientists can piece together how continents once fit together.
Next, they used magnetic signals preserved in rocks to determine past latitudes. When rocks form, tiny magnetic minerals inside them align with Earth’s magnetic field. Because the angle of this field changes depending on latitude, scientists can use these magnetic clues to estimate where the rock was located when it formed. By combining this with information about the rock’s age, they can trace the long journey of continents across the globe.
This new model has exciting uses beyond mapping ancient geography. It can help scientists better understand how life on Earth has changed over time. Fossils found in mountain rocks can now be placed more accurately in their original locations, helping researchers study how species evolved, migrated, or went extinct in response to changing climates.
The model also allows scientists to study major events like mass extinctions in greater detail. By knowing which regions became too harsh for life and which areas remained habitable, researchers can learn valuable lessons about how ecosystems respond to environmental change.
Looking ahead, the team plans to extend the model even further back in time, possibly to 550 million years ago during the early rise of complex life. For now, this tool offers a fascinating way to explore Earth’s deep history and discover that the ground beneath your feet has traveled a long and remarkable journey.
