Re: Son of the Murderous Digit

In a message dated 98-08-11 16:01:00 EDT, you write:

<< They are probably closest related to the extinct Psilopterids and,
 through them, to the phorusracid "terror birds".  Seriemas have an enlarged
 claw on digit 2, among other things, which has caused some to compare them to
 Velociraptor et al (though they certainly cluster within living birds).  >>

  Being very ignorant of the osteology of the phorusracid "terror birds" the
obvious question is: how well do we know the structure of their pes? Did any
possess the "dromaeosaurian" configuration of the seriema? That would almost
be too good to be true! Dan Varner.
