Re: Mesozoic birds made insects shrink
It reminds me of the idea that birds out-competed pterosaurs. I would imagine
that had the K/T extinction not occured, the birds would still eventually lead
the pterosaurs to extinction. They must have been quite diverse/advanced by the
Campanian when only very large pterodactyls were left. And since the
ramphorynchoids and small pterosaurs died out as the birds were just starting
to emerge, it seems to me that the Aves were explosively successful from the
outset (Archaeopteryx). Does anyone have more info on this idea?
