Dozens of footprints from ancient sauropods, a kind of creature that scientists believe may have been the largest dinosaur ever, have been discovered in Scotland. These 170-million-year-old footprints are also the oldest ever discovered in Scotland. The sauropod footprints were located in a lagoon on the Isle of Skye, near a group of footprints from theropods, more ancient cousins of Tyrannosaurus Rex. “It shows both long-necked and meat-eaters were on the same site at the same time living together, side-by-side,” Dr. Steve Brusatte of Edinburgh University told the Telegraph. “It captures a moment in time 170 million years ago when they were just hanging out in a lagoon, living on the beach, back when Scotland was much warmer and dinosaurs were beginning their march to global dominance.”

Scientists believe that the sauropods who left the footprints were least 49 feet long and weighed more than 10 tons. The theropods are thought to have stood at least six feet tall. In total, researchers documented approximately 50 footprints near Brothers’ Point on the Isle of Skye’s Trotternish peninsula. This wet and wild location made it difficult for scientists to study the footprints on-site, though drones helped, particularly in creating a map of the dig site.

Despite its challenging environment, Scotland‘s Isle of Skye has proven to be a bountiful trove of dinosaur fossils. “This tracksite is the second discovery of sauropod footprints on Skye,” study lead author Paige dePolo told Science Daily. “It was found in rocks that were slightly older than those previously found at Duntulm on the island and demonstrates the presence of sauropods in this part of the world through a longer timescale than previously known. This site is a useful building block for us to continue fleshing out a picture of what dinosaurs were like on Skye in the Middle Jurassic.”
