The only references Google could find were on creationist sites, citing a geological paper from 1829. Sanhorn is not mentioned elsewhere - or in my atlas. I would expect it to be in Norway although there is no way to be sure.
Given that there is a nountain there it is obvious that there has been uplift, and the date of the paper clearly means that that possiiblity was not considered at the time. Given the obscurity of the source and location it is unlikely that there has been any serious check.
Here is one source mentioning a fossil whale found in Norway :
"At Smestad in Brum (near Oslo, Norway), a 20 metres long, almost complete skeleton of a baleen whale was found in 1978, in compact blue clay. The whalemust have stranded in a shallow bay, which seabottom sediments today lie 106 metres above sea level. This is due to the rising of the land (isostasy) after the last Ice Age. The whale died about 8500-9000 years ago."
[Added by Edit] At this point it seems to me that the most likely explanation is that the whale fossil was found much lower on the mountain and that it was raised to that point by isostatic rebound. Rebounds of over 200m are apparent from the geology.
Until proper documentation of the find is available I will stick with this explanation.
