00:00Imagine discovering where a fossil was located 200 million years ago.
00:04Scientists at the University of Barcelona have made that possible with a new online tool.
00:10It's called the PaleoCoordinates Calculator, or PACA.
00:14The platform converts today's coordinates into their ancient positions as Earth's tectonic plates moved.
00:21Users simply upload a file with a location and its geological age.
00:25In just seconds, PACA reconstructs where that place existed in Earth's distant past.
00:31The tool compares results using five major global plate tectonic models.
00:36It also measures uncertainty, helping researchers judge the reliability of each reconstruction.
00:42Scientists tested PACA with 142 reconstructions from locations around the world.
00:48The results showed an average error of less than 17 meters.
00:51That accuracy closely matches traditional desktop software, while making the process much easier.
00:58Researchers say PACA could help scientists, educators, and students explore Earth's ancient history like never before.
