There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
I made a little escalation with a picture available in the web of the skull in perfect side view in order to found the Condylobasal length:

I got a CBL of 331 mm. Of course this is just an estimation based on the image, but this match very well with the correct side view of the skull.

Now, based in the picture that you posted of the mandible, I still think that between 240-250 mm is the correct length. I may be wrong, but this is what I got with the methods avialable.
