From the time of their discovery by way of the nineteen seventies, dinosaurs have been typically depicted as loners. They led somewhat solitary lives and didn’t care substantially for their offspring. “Lay ’em and depart ’em” was their parenting model. But by the stop of the 20th century, a really diverse impression of dinosaurs experienced emerged.

An huge bone bed of the horned dinosaur Centrosaurus only built perception in the context of social behavior. Nesting grounds for dinosaurs this kind of as Maiasaura held proof of parental care. And deposits of a number of carnivores this kind of as Allosaurus and Albertosaurus lifted the concern of whether some predators have been pack hunters. 

Some bits of proof have stood up superior than other folks. Mass assemblages of huge carnivores, for illustration, are controversial and have at times been recast. A bone bed of more than 48 Allosaurus in jap Utah is not proof of pack hunting, but of repeated drought and flooding that killed these animals and buried them in the identical put. But nesting grounds and keep track of internet sites have yielded superior proof of behavior — not just for the herbivores, but for some carnivores, as well. Tracks remaining by raptors and tyrannosaurs show that these toothy dinosaurs flocked jointly at the very least some of the time, and far more proof is turned up every calendar year.
