I don't like these fossils. I don't hate them as much as I did, as half of them are Ice type, which is my favorite type, but I think they made this terrible. Perhaps in the next version of the game, we will get other fossils fragments to create their true form.
As we go on, I don't think they will continue this into other generations, I think it is just something for this region. However, if they continue on, perhaps they will make them better or at least make the bodies work with each other instead of this randomness that doesn't even have the full bodies. I also hate the idea that they don't have evolutions, which is a dumb concept. Especially since most dino are drastically different from when they are born to when they grow.
