  We study aspects of entanglement and extremal surfaces in various families of
spacetimes exhibiting cosmological, Big-Crunch, singularities, in particular
isotropic $AdS$ Kasner. The classical extremal surface dips into the bulk
radial and time directions. Explicitly analysing the extremization equations in
the semiclassical region far from the singularity, we find the surface bends in
the direction away from the singularity. In the 2-dim cosmologies obtained by
dimensional reduction of these and other singularities, we have studied quantum
extremal surfaces by extremizing the generalized entropy. The resulting
extremization shows the quantum extremal surfaces to always be driven to the
semiclassical region far from the singularity. We give some comments and
speculations on our analysis.
