Now that I've thought about it more... this is the real reason we didn't allowed the article til now.

It doesn't matter if a creature only appears as bones (Edmontosaurus only appeard as a skull in TLW). We only made articles about creatures that InGen recreated (in any media).

This is probably because there isn't much to tell about creatures that only appear as paintings or bones.

But, as Justisaurus noted, the Alamosaurus skeleton appeared in one of the best scenes of the first movie, so it is a well known fenomenon.
