With that distinct shadow It certainly looks like a highly localised elevated area, A mountain of some sort, A isolated mountain would, I would have thought, almost certainly imply some sort of volcanisim.

Though whether one can strictly call something taking place at liquid nitrogen temperatures a "Volcano" Im not sure. I wonder if there is a more appropriate name?

NASA may be right, Looking at it again, if there was a "Volcanic" cone thein I would expect to see a bright crescent on the sunside. However, I still think it looks like a shadow.

Also, notice the circular features in the centre of the picture that seem to be in line with whateveritis. Could it be a "Hot Spot"? The Hawaii of Titan??

(Hmmn! Surfing on liquid Nit! Seems a bit "Dark Star" to me)

Hmmm -- I think you may have something there.... I didn't notice those other, apparently aligned spots before.

What struck me was the similarity of the black whateveritis to the black smokers photographed all over Neptune's moon Triton, by Voyager, years ago.... Of course those were very clearly identifiable, due to the extremely low density atmosphere on Triton. I figure that if you were to put those on Titan, they'd look just like whateveritis.

As for plate tectonics.... while I buy the hotspot idea on Titan, I think that effect could be had with just a single, global 'plate' (shell). No signs yet of Earth-style multi-plate tectonics
