Re: Killer Pterosaurs?
I'm just a second(ish) year paleontology student transferring to the
University of Alberta in September but I'd like to comment on this as my
In my opinion, dinosaur species were less diverse than in previous times.
They also were probably more specialized and had a limited scope of
environmental potential...and while their ranges may have been large, a
slight change would vastly limit those ranges and therefore constrict
populations. This would mean that a combination of things, such as
Angiosperms taking over traditional Gymnosperm environments, climate changes
etc., would hit like the equivalent of a semi-truck running into an ant
hill. This, of course, would be moving at a much slower pace but still
effective all the same. Therefore, a single cause would not only be less
likely, but would be almost impossible to locate and then prove. If what
I've said is right (or even partly so), a combination of effects had primed
the non-avian dinosaurs for the final KO punch from a celestial body.
Therefore, I suggest that even without knowledge of how pathology can move
through a lineage, we can rule out any single disease carried by Pterosaurs
or any other carriers as a main cause of extinction. It may have contributed
to the demise of one or more lineage but is certainly not to blame. My
personal opinion is that disease didn't wipe them out. I don't know much
about pathological movement and infection, but I certainly can't think of
any disease in modern times that could threaten to put an entire genus of
animals to extinction, nevermind almost an entire Class.
Hope I didn't make an fool of myself there with misinformation and silly
