as we probably all know, teratorns have traditionally been linked to
cathartids. In recent years,however this is far from universally accepted.
For example, I seem to remember Feduccia mentioning in 'The Origin and
Evolution of Birds' that there were reasons to link teratorns to
pelecaniforms or storks. Of course, Feduccia did not mention what reasons
those were (as far as I remember.)
So my question is: has any consensus been reached or persuasive theory been
made as to what birds teratorns were most closely related to?
P.S. I've seen a height-estimate of 2 meters for Argentavis. Is that
thanks in advance,
