Kinda. Fossils are bone that have had the calcium leached out of them and had it replaced with rock. As is obvious to anyone who takes the time to think about it, the rock the fossil is made of is the same type of rock that surrpunds them. So it makes sense for the magic that animates the fossile to also affects some of the rock, so the gaps in between the bone are often filled with stone (I did the rhyme on purpose because reasons) so they're kind of like a skeleton/golem hybrid.
