I think that the survival thing largely comes down to "dinosaurs big, other critters small" rather than being anything very complicated. Bigger critters would assumedly be more sensitive to disruption of their ecosystem since they have a much larger biomass to support; also being ectothermic probably really sucked what with many years of blocked sunlight and all. Turtles and such, on the other hand being much smaller, would have lesser requirements for survival and thus would have a much easier time adapting to meet them. Meteor or not, it just came down to huge size not being very evolutionarily adaptive. Only reason the suckers hung on for so damn long in the first place is that life in any form is a very persistent thing.
