The notion of special valuations, i.e. finitely generated valuations inducing klt degenerations of Fano
varieties, plays an important role in the recent study of K-stability and moduli of Fano varieties. Given an affine
log Calabi-Yau variety $U$, we show that its special skeleton, namely the space of special valuations in the dual
complex of $U$, is independent of the choice of its Fano compactifications. Consequently, the special skeleton of
$U$ is invariant under the action of $\text{Aut}(U)$. As an example, when $U$ is the complement of a Markov cubic surface
in the affine three-space, we show that the action of three Vieta involutions on the special skeleton exhibits a
surprising connection with dynamics on the hyperbolic plane.
