Re: disease-carrying varmints biting dinos
Two separate issue:
1) Did disease-bearing organisms spread diseases among dinosaurs? Almost
certainly yes. Indeed, to infer otherwise is to infer a difference between
Cretaceous and modern ecosystems that is unwarranted by current evidence?
2) Did said disease cause the K/Pg extinctions? Almost certainly not!!
Consider the wide spectrum of organisms that were affected (from [most]
coccolithophorids and inoceramids and ammonoids to pterosaurs and
non-avian dinosaurs and so forth), any hypothesis that would just affect
one but not all is an unlikely candidate.
