I'm pouring over this paper on phylogeny tyrannosauroid dinosaurs. I'm
not understanding what is being measure in the premaxilla bone, which is
a measured characteristic 13. Does anyone have an example of a diagram
of what is being measured?

(Premaxilla orientationa and shape of anterior margin)

I don't know what ventral and anterior margins are and what angle is
being measured.


Article: http://www.nature.com/articles/srep20252

13) Premaxilla, orientation and shape of anterior margin: smoothly curved
and projection posterodorsally, angle between ventral margin of premaxilla
and anterior margin is less than 90 degrees (0); smoothly curved and
projecting vertically or slightly anterodorsally, angle between
ventral margin of premaxilla and anterior margin is equal to or greater
than 90 degrees (1); projecting vertically or slightly anterodorsally,
with a discrete inflection point between a more vertical ventral portion
and a more horizontal dorsal portion (2). ORDERED (Brusatte et al.
2010:13).

This character is slightly modified following Brusatte et al. (2014:485).
We have transformed the original character of Brusatte et al. (2010:13)
into an ordered multistate by adding a new intermediate state referring
to an approximately vertical (or slightly anterodorsally inclined)
anterior margin of the ventral portion of the premaxilla. State 2 now
refers to a special condition of this state, in which the anterior margin
is vertical (or anterodorsally inclined) and there is also a discrete
inflection point between the more vertical ventral portion of the
anterior margin and the more horizontal dorsal portion of the margin.
Taxa with this condition, therefore, do not possess a smoothly curved
anterior margin of the premaxilla. Tyrannosauroids are characterized by
either state 1 or state 2, with state 2 referring to a subset of basal
tyrannosauroids (Dilong, Guanlong, Kileskus, Proceratosaurus,
Sinotyrannus).

I think they're talking about a lateral (side) view of the angle between
the bottom of the premaxilla (where the teeth are) and the front.

I tried comparing a few images of Tyrannosaurus and Dilong skulls, and
there seems to be quite a lot of variation. Some of the T. rex skulls do
seem to show an inflection point, but others seem pretty smoothly
curved. A Nature paper is probably the wrong one to look to for good
character descriptions. I'd look at the references to see if anything is
illustrated there.
