- Fossil footprints discovered at Dinosaur Provincial Park in Alberta, Canada, provide the first concrete evidence of mixed-species herding behaviour among dinosaurs.
- The tracks show different dinosaur species, including horned and armoured dinosaurs, travelled together, similar to modern wildebeest and zebra.
- Researchers also found tracks of two tyrannosaurs walking alongside the herd, suggesting multispecies herding may have been a defence strategy against apex predators.
- The findings, detailed in the journal PLOS One, shed new light on social interaction among prehistoric beasts.
- Further excavations at the site are expected to reveal more details about how dinosaurs of different species interacted and behaved in their natural environment.
