Gigantism in dinosaurs

Gigantism in dinosaurs refers to an abnormal growth condition where certain species grow to enormous sizes due to excessive activity of growth hormones during their development. This results in extremely large body sizes, like that of the long-necked sauropods such as Argentinosaurus. While natural evolution favored large size for advantages like predator defense and resource access, gigantism caused by hormonal imbalances can lead to health issues and was likely rare among dinosaurs. Overall, true gigantism was a key factor in some dinosaurs reaching the largest sizes in terrestrial animals history.
