Ancient Mongolian Trackway Rediscovered, Revealing 31 Giant Dinosaur Footprints

Rediscovered in northern Mongolia, a 120-million-year-old tracksite in the Shinekhudag Formation preserves 31 footprints—two parallel sauropod trackways suggesting herd movement and five theropod tracks—indicating large predators converged at a drying lake edge; first noted in 1950 but lost for decades, the site could yield bones nearby and helps fill gaps in Mongolia’s early Cretaceous dinosaur record.
