Second this. I too have heard the same theory.Interesting. I once read an article stating that the reason invertebrates were so big in prehistoric times (dragonflies with 28" wingspans, etc.) was due to the atmosphere having a higher oxygen content than it has now.
Since lice aren't obligatory parasites like fleas or mosquitoes, the K-T doesn't seem to present an insurmountable barrier.I would have expected lice to evolve well after the K/T boundary, but here they are. I wonder if they jumped from mammals to dinosaurs or vice versa.
