The thing about the K-T extinction is that there is no real pattern to
what did and did not survive. Lots of indicators have been proposed:
land vs. water-dwelling, large vs. small, endothermic vs. ectothermic,
etc. But none of them fits the data, which suggests that the strongest
factor affecting survival was sheer dumb luck.
So it's not really possible to answer your question of which dinosaurs
were most likely to survive that event, beyond the obvious observation
that birds evidently did (as you noticed). It could just as easily
have been hadrosaurs or titanosaurs; and the surviving mammals could
easily have not included the lineage that led to us.

> Good day to all listmembers! I would like to ask, which non-avian dinosaur species from the terminal Cretaceous are (according to you) most likely to survive the extinction 66 million years ago? Small bird like species? Specialised aquatic or burrowing forms? Are there any hints of favourable adaptations for the possible survival in the fossil record? Thank you for your opinions! Tom
