Again, the image is wrong -- the fossil does not correctly reflect the
shape of the living animal. In life, and in the 10th and 11th specimens
even in death, the 1st toe pointed forward just like the others. The 1st
toe also looks longer than it was, because it's been squished away from
the rest of the foot (except the 1st metatarsal).
Most fossils are squished flat. Steamrollered. Roadkilled. Often, though
not in the plated limestones of Bavaria, this goes so far as to
distorting bones without even breaking them. It must be taken into
account when reconstructing the living animals.
I forgot if Kevin Middleton's thesis has been published. It shows that
the orientation of the 1st toe depends on whether the 1st metatarsal is
twisted, and shows that it's not twisted in *Archaeopteryx*.
So what would an Archie track look like?
