Abstract: We take a first step towards understanding the relationship between foliations
and universally tight contact structures in hyperbolic manifolds. If a surface
bundle over a circle has pseudo-Anosov holonomy, we obtain a classification of
``extremal'' tight contact structures. Specifically, there is exactly one
contact structure whose Euler class, when evaluated on the fiber, equals the
Euler number of the fiber. This rigidity theorem is a consequence of properties
of the action of pseudo-Anosov maps on the complex of curves of the fiber and a
remarkable flexibility property of convex surfaces in such a space. Indeed this
flexibility may be seen in surface bundles over an interval where the analogous
classification theorem is also established.
