Step back in time 150 million years to the Jurassic Period, where a colossal creature roamed the Earth. In the quaint French village of Plagne, an extraordinary discovery has unveiled the world’s longest sauropod trackway, offering a glimpse into the lives of these gentle giants.
The Plagne Sauropod Trackway
Uncovered in 2009, this remarkable trackway stretches over 155 meters (508 feet), surpassing the previous record holder in Texas. The series of 110 footprints, left by a massive sauropod, provides invaluable insights into the anatomy, behavior, and environment of these prehistoric behemoths.
A Glimpse into the Past
- A New Species: Scientists have classified the Plagne sauropod as Brontopodus plagnensis, a new ichnospecies based on its unique track characteristics.
- Colossal Proportions: The creature that left these prints was estimated to be at least 35 meters (115 feet) long and weighed between 35 and 40 tons.
- Gait and Speed: The trackway reveals a leisurely pace of 4 km/h (2.5 mph), with an average stride of 2.8 meters (9 feet).
- Foot and Hand Anatomy: The well-preserved footprints showcase five toes on each foot and five fingers on each hand, providing clues about the sauropod’s weight-bearing capabilities.
Environmental Insights
The Plagne trackway offers a window into the Jurassic environment. The limestone platform where the tracks were found suggests a shallow marine setting with nearby islands, providing ideal conditions for sauropod foraging and migration.
A Testament to Ancient Giants
The Plagne sauropod trackway stands as a testament to the dominance of sauropods during the Jurassic Period. These gentle giants, with their colossal size and unique adaptations, continue to captivate our imaginations and inspire scientific exploration.
