Re: Cope’s Rule in the Pterosauria - Hone & Benton 2007



There are multiple advantages to increasing size, mass, and wingloading in pterosaurs (commensurate with launch ability). It seems to me that, with some exceptions, one could expect them to evolve toward larger size. Which has nothing to do with Cope's Rule of course.

Ugh. Hone and Benton are at it again? When will they learn that Cope's
Rule just. doesn't. work.? Cope's Rule only "works" in a lineage that
starts smaller than it ends up and dies off before it reduces in size. It
isn't possible over broad taxonomic ranges like H & B try and prove with
this paper, or as Hone tries to do with his dinosaur paper from a few years
back. Let it go, fellas! Sheesh.
