Oh, indeed. And we have geological inversions with fish over mammals, and we have dino bones that occasionally show up in silurian debris. However, this is a field of inquiry with a wide amount of potential variation. A fossilized bone has no say about where chance diversions of strata will take it. Fortunately, the science of this stuff doesn't look at one bone, and try to draw a conclusion. It looks at all the data we have available, and groups it statistically, and, statistically, you have no case. It is clear as a bell, looking at the accumulations of evidence, that the trend in fossils, viewed from high above, is a rather orderly, continuous march from small to large, simple to complex, monolithic to segmented, isolated to conglomerated.
I guess I should say, it is clear as a bell, unless they have a theological iron in the fire.
