Bonding behaviour in animals We can't go back in time to find out how allosaurs hunted but we have other clues as to how they behaved. We can observe modern distant relatives such as birds and crocodilians to find similar behaviours. When we observe most birds, both behaviours are observed. We see some in flocks and large social groups but others have a minimum amount of contact with their own species.
Crocodilians are generally solitary by nature.
The main interactions with their own kind usually include mating and defending territorial boundaries. Mother alligators are caring and protective of their young only while they are small. Once they have grown to sub-adult size, mother alligators will happily make a meal of them. Like their modern relatives, dinosaurs could be social or antisocial depending on circumstances of age, population dynamics or availability of food. Crocodiles bond when hunting requires it.
