The evidence for group behavior among dinosaurs includes what?

Evidence for group behavior among dinosaurs includes fossil findings of trackways showing multiple individuals moving together, suggesting herding behavior. Additionally, mass death sites, where numerous individuals of the same species are found together, indicate social interactions. Some fossils also reveal nesting sites with multiple nests in proximity, implying parental care and communal breeding. These findings collectively suggest that many dinosaur species engaged in social behaviors similar to those observed in modern animals.
