I have a photo of a decomposing dog which is in a water logged environment. My peers and I are debating how long that body has been decomposing. They are saying it is at least a year old. I however think it's much more recent (1-3 months).
My understanding is that when a body is put into a wet environment either partially submerged or fully it speeds up the decomposition process provided the water is not lacking oxygen such as if it was deep on the ocean floor.
The carcass has its skull fully decomposed, which I think is due to the bacteria rich water having more access to surface area through the various orifices and also the skull having much less flesh than the rest of the body.
The torso looks for the most part intact, and I don't see any bloating from gas buildup (not sure when and how long such a feature would be present), and there appears to be a pink area which could be muscle.
Would these features be typical of a recent death in this type of environment or am I overlooking some other important processes that could be speeding up or slowing down the decomposition?
