Never understood how birds are the only remaining dinosaurs... wonder what made dinos so vulnerable to this event, where many other large species (crocs, turtles, fish, etc) survive to this day. One might think that some small dinosaurs, or aquatic/marine species would have found a niche on some continent. Population bottleneck, I guess. Imagine if no dinosaurs at all had survived... maybe we'd have a lot more large insects and bats species filling the skies.
