Tenontosaurus

["Jaime Headden" <jaemei@hotmail.com>]

Who has anything to comment on the unusual placement of the jugular 
foramen on Tenonto's cheek? This position of the foramen is unlike the 
specimens of hypsilophodontians and iguanodontians that I know of (or 
that have these bones preserved) which makes me suspect that, like many 
other members of these groups, along with the rostrocaudally short jugal 
and huge quadratojugal, Tenonto may codify his own taxonomic status away 
from mainstream Iguanodontidae, perhaps closer to Dryosauridae.

And before I forget, what about the idea of a quadrupedal 
*Thescelosaurus*? The elongate humerus, robust forelimbs and huge 
carpals, short hindlimbs, and pelvis seemingly more like that of the 
quadrupedal iguanodontians and hadrosaurs. The ossified tendons are less 
compacted and constricting as seen in those other groups I mentioned 
above aside from Dryosauridae. Hmmm....

I'm probably sticking both feet in my mouth, but....
