I will like to see a picture of Baikal in this form:
In full side view, with no obstacles in the image. That will be perfect for image comparisons.
About the bones, I highly doubt that they will give details to any particular person, BUT it is posible that through an organization like an University or a student of Biology, they could give details. I have my eyes over Tigerluver, after all, he is a Biology student.
Take in count that Baikal is still alive (thank God), so I think that the best thing to get rigth now will be not weight but body measurements, accurately taken.
The "length of 8 ft" is inaccurate from my point of view, we need a clear description of its body length (straight line), height and if its possible chest girth.
