Of course it is, and paleontologists take care to avoid error. Their work is exacting and requires a great deal of knowledge and experience, sometimes assisted by scientists from other fields.
It is interesting what can be learned from "old bones".
Does it matter? Not particularly, not at all to the incurious.
For those with a spark of interest in the world, it's interesting.
You can't learn everything about the animal but a lot can be
pieced together. There is a fossil site where a lot of animals died
in what appears to have been an extended drought and drying waterhole.
Tropical, because crocodile bones. Some of the camel and rhino bones had lain on the surface for
around a year before burial, others were fresher, probably died
in the mud. Similar scenes are acted out in Africa.
Some bones show scars from being scavenged by a giant
piglike animal. One shoulder blade has a hoofprint
broken right through it.
A lot of information can be gathered about the site.
For those incapable of appreciating such things, too
bad for them.
