Doctor Andrew Brownlow, who carried out an autopsy on the whale, admitted he was not sure how the mammal came to swim up the Solway but concluded it might have simply been lost.
The juvenile male may have been following a shoal of fish or other food source and become disorientated.
The Fin Whale normally lives in the mid Atlantic.
The species spends the summer near the Arctic but comes further south in the winter.
A post mortem has been carried out on a 25-tonne whale washed up on a beach on the Galloway coastline.
The 57 foot long Fin Whale, believed to be around 15 years old, was discovered on the beach near Newton Stewart on Sunday evening (17th February).
It was still alive when it was found but was left stranded by the tide and did not survive.
An examination was carried out by marine expert Dr Andrew Brownlow.
His preliminary findings show the whale died due to being unable to support its massive weight out of the water and probably drowned after inhaling sea water.
Vets are now carrying out an autopsy on the 60 foot whale to establish the cause of death.
Attempts are currently being made to move the whale so that an autopsy can take place.
Vet Andrew Brownlow said it would take most of the day to examine the animal to establish how it died.
A digger will then bury the animal close to the beach.
Vets will begin investigating how a 60ft dead whale ended up on a Solway beach.
