Glass half Panda'd
those reconstructions are done so in a way to prove their claims right. because if you have the top half skeleton of a human, how would you know what its' legs looked like or how long they were. you see this fascinates me, a scientist digs up some old bones say a head or a tooth, and he is able to recontruct the whole animal or human that it belonged to. how is that possible, that is against logic and against things that make sense, because contructing the whole body of a whale for example, just because you have found a fin, makes no sense.
surely you understand that.
Actually I do. When I was a kid, I used to wonder about that sort of thing all the time. "How in the world can they tell what fits where?" Well, for the most part, I think people look to fossil imprints, similar to something like this:

I imagine that this, coupled with the many thousands of hours of scientific work finding out what connected to where (making sure it actually fit, and didnt' just cram it where it looked right.) AND some of the rare cases where the bones were actually buried in tact (like, finding a whole T-Rex skeleton mostly put together in the way it would have been) help show the case that there is some evidence for how the skeletons fit together.
It's not as if dinosaurs and other creatures' bones were thrown half in one part of the globe, and half in another, or that we only have a tooth, and we build the creature around that... it's more like we find almost a complete skeleton.... (if we look hard enough.) and work from there. In some cases, we aren't so lucky, other animals could have dragged a few bones away, they could have been turned into fossil fuels by now, some may have been crushed by the weight of other structures formed atop of these bones... and this is why in some cases, we aren't so lucky to find the whole bird in tact.
