  We study five-dimensional Kasner cosmologies in the vicinity of a conifold
locus occurring in a time-dependent Calabi-Yau compactification of M-theory.
The dynamics of M2-brane winding modes, which become light in this region, is
taken into account using a suitable gauged supergravity action. We find
cosmological solutions which interpolate between the two branches of the
transition, establishing that conifold transitions can be realized dynamically.
However, generic solutions do not correspond to transitions, but to the moduli
getting trapped close to the conifold locus. This effect results from an
interplay between the scalar potential and Hubble friction. We show that the
dynamics does not depend on the details of the potential, but only on its
overall shape.
