The line drawing includes all features indentified from site 62, yes. The photo is of a single spectacular fossil (evidently, it's uncommon to get much preserved back of the head in Pakicetus).

Note the difference between mosaic-ing a specimen (definitely bad paleontology) and showing in a drawing what features are represented in one fossil or another and what is unattested.
