Head of Tyrannosaurus - Anatomy Primer

EDIT #1: Removed the bit of text below:

(...)and anchors the iris. The sclerotic ring also limits the shape of the pupil to round or oval.

The first bit, after more research, turns out to be factually wrong. The sclerotic ring is a relatively passive structure within the sclera that helps maintain the shape of the eye with no direct relation with the iris or lens which are anchored, respectively, directly and via the cilliary body to the sclera.
As *Jabrosky rightly points out below in the comments, the second is poor inference from overgeneralization and, frankly, misinterpretation of this review. Shape of the pupil is best correlated with the optical structure of the lens which in turn seems pretty labile in evolutionary terms ( [link] ). It also turns out there is a bird with slitted pupils.

Elsewhere someone, who shall remain nameless, tried to critique the anatomy on this 3D model of "Tyrannosaurus".
It's not so much the, perhaps apparent, futility of critiquing the anatomy of a monster, as that's what dinosaurs are when portrayed within fiction, but that when trying to do so this person only managed to reveal their ignorance on the subject.

I'm not pretending that this is the most accurate reference ever for theropod head anatomy. It is however far less wrong than the example alluded to above.
I do however hope that it's complete and intelligible enough that the most common mistakes cropping up on dinosaurs fictional or otherwise aren't perpetuated. Perhaps a lofty aim: people will continue to pull things out of their proverbial rectum but here's my bit in this good fight anyway.

With the above, I'm not closing this to critique, either artistic or scientific. Feel free to point out where I'm mistaken: I'd like to perpetuate as few misapprehensions as possible myself. I'd like to know also if this was an effective way of conveying this information. Is this is too crowded? The sketchy style doesn't become it? Are the captions sufficiently devoid of jargon?
