Humps are common in dinosaurs, and can be used for heat regulation - when they might look like a kind of sail - for display, or for food storage.

It is probably not for heat regulation, since normally a hump of this type would need an extensive blood supply, and there would be evidence within the surrounding bone - the team did not find this.

It should be noted that the rate of gas engine heat pump is limited regulation, and can not be any regulation, which is the work of the engine and compressor characteristics.
