Context – Herd mentality in Jurassic dinosaur

Concept –

Fossils unearthed in Argentina’s southern Patagonia region is the oldest-known evidence that some dinosaurs thrived in a complex, well-organised herd structure, with adults caring for the young and sharing a communal nesting ground.
The fossils include more than100 dinosaur eggs and the bones of about 80 juveniles and adults of a Jurassic Period plant-eating species called Mussauruspatagonicus.
The animals experienced a mass-death event, probably caused by a drought, and their bodies were subsequently buried by wind-blown dust.
The animals were found to have been grouped by age at the time of their deaths. This phenomenon, called “age segregation,” signals a complex social structure.
