RE: Therizinosaur track from Denali National Park, Alaska
*Balaur* also has an enlarged, forward-pointing pedal digit I. The Alaska
track is missing the tips of digit I and II, so we cannot be sure they did not
have the large raised claws of a similar dromaeosaurid. Now THAT would be some
Fiorillo and Adams (2012) refer the Alaska track to *Saurexallopus* isp.. Does
this imply that they also consider *S. lovei* and *S. zerbsti* to also be
therizinosauroid tracks, or are ichnotaxa still irrespective of phylogeny?
