If the Flood catastrophe occurred during the usual laying time for the
dinos, then attempted nesting would of course be expected on any exposed
sediments during the catastrophe.

If the rocks were limestones or sandstones cemented by calcium carbonates,
then there is not a real problem. Concrete, using Portland Cement which
made from lime, reaches 98% maximum strength in 28 days. The proposed
impact storm is thought to have lasted for some 150 days. So at least some
of the limestones or sandstones could have reached pretty near maximum
strength during the impact storm.

Don't forget to comput the heat reducing factors, such as:
1. Impact explosion created 2NO which radiates heat at high rates in the IR
2. Impact ejected dust and aerosols in the high atmosphere which will block
much of the solar radiation resulting in conditions similar to the feared
nuclear winter effect from nuclear war.
3. Surface blasts in water will inject vast amounts of water vapor into the
high atmosphere which will condense on dust and aerosols. Constant rain
would continually wash the atmosphere of many contaminants.
4. As the atmosphere warms up it will expand and reduce the optical depth
caused by dust and aerosols. IR radiation can more freely escape within
the IR windows not blocked by CO2.
