Overview

• A PLOS One study presents the first 76-million-year-old evidence of different dinosaur species herding together in Alberta’s Dinosaur Provincial Park.
• Researchers identified 13 ceratopsian tracks, prints from an ankylosaurid and a small carnivorous dinosaur footprint in the same sediment layer.
• Parallel tracks left by two large tyrannosaurs intersected the herd’s path, hinting at potential predator–prey interactions.
• Scientists applied footprint pattern imaging to discover several additional tracksites across the park’s varied terrain.
• Teams plan further excavations and behavioral analyses to deepen understanding of dinosaur social dynamics and site formation.
