  In models with extra dimensions that accommodate a TeV-scale gravity, small
black holes could be produced in near future accelerator experiments. Such
small black holes, whose gravitational radius is mush smaller than the
characteristic size of extra dimensions (compactification radius in flat or AdS
radius in warped extra dimensions) can be very well described by asymptotically
flat solutions, thus losing the information about the global geometry of the
extra manifold. One might conclude that such small black holes would be
indistinguishable in different scenarios. We argue that important differences
still exist, especially regarding experimental signature in colliders, which
may help us distinguish between the various extra dimensional scenarios. The
main differences come from the fact that most of the models with the warped
extra dimension have an additional discrete $Z_2$ symmetry that makes the brane
behave as if it were an infinite tension brane.
