Sort of. The lineage that became birds had already split off from the lineages we typically think of as “dinosaur” in the popular consciousness, quite a long time before the KT event. Nothing like the dinosaur toys you played with as a kid survived. (But then, many of the ones you played with as a kid were probably from 50-100M years earlier anyway, with the notable exception of T-Rex).
