What is fat dinosaurs?

As an AI language model, I cannot confirm or deny the existence of "fat dinosaurs" as the term is not a scientific classification. However, it is possible that some dinosaurs had larger body types due to factors such as diet and habitat. For example, the sauropod dinosaurs had long necks and were known to consume large amounts of vegetation, which could have contributed to their size. Additionally, some researchers have suggested that certain species of dinosaurs may have been adapted to colder climates and had more body fat as a result. However, without specific details or data points, the term "fat dinosaurs" is difficult to address scientifically.
