A solitary Deinonychus could not kill an adult tenontosaur, suggesting that pack hunting is possible. [4] A 2007 study by Roach and Brinkman has called into question the cooperative pack hunting behavior of Deinonychus, based on what is known of modern carnivore hunting and the taphonomy of tenontosaur sites.
Suzanne Batra introduced the term "eusocial" [1] after studying nesting in Halictid bees including Halictus latisignatus, [2] pictured.. The term "eusocial" was introduced in 1966 by Suzanne Batra, who used it to describe nesting behavior in Halictid bees, on a scale of subsocial/solitary, colonial/communal, semisocial, and eusocial, where a colony is started by a single individual.
The discovery of the Deinonychus fossils is considered one of the most important fossil finds in history. [22] [24] Deinonychus was an active predator that clearly killed its prey by leaping and slashing or stabbing with its "terrible claw", the meaning of the animal's genus name. Ostrom also suggested that it had hunted in packs.
Primate sociality is an area of primatology that aims to study the interactions between three main elements of a primate social network: the social organisation, the social structure and the mating system. The intersection of these three structures describe the socially complex behaviours and relationships occurring among adult males and ...
Deinonychosauria is a clade of paravian dinosaurs which lived from the Late Jurassic to the Late Cretaceous periods. Fossils have been found across the globe in North America, Europe, Africa, Asia, South America, and Antarctica, [2] with fossilized teeth giving credence to the possibility that they inhabited Australia as well.

The individuals giving up their own reproductive success form a sterile caste of workers within the group. All species that practice reproductive altruism produce one or more queens, the only breeding females, who are larger than the rest. The remainder of the society is composed of a few breeding males, sterile male and female workers, and the ...
Social grooming is a behavior in which social animals, including humans, clean or maintain one another's bodies or appearances. A related term, allogrooming , indicates social grooming between members of the same species.
A pack of Deinonychus get revenge on Blue Back, a Tyrannosaurus who stole their well-earned meal, by stealing all of his family's eggs but one. A group of four Deinonychus successfully stalk and kill a Saltasaurus out on the savannah. However, they are soon chased off their kill by the Tyrannosaurus Blue Back, who kills one of the Deinonychus ...
