It has not "turned out" that B. walkeri is a juvenile: there is a difference
of opinion, which is hardly settled.  Lack of fusion between some skull
bones and some vertebrae suggest it was a subadult; fusion of the sternal
plates together, however, suggest it may have been adult.  Difficult to say
for certain.

>2) What is known from the African "Baryonyx sp"?

Wait a month or so, and you'll know a LOT more about it.

Trust me on this... :-)
