This is going to sound silly, but bear with me, because I just noticed
something. Grab you scale dinosaur models that you have sitting around
(you got to have some) and hold the Triceratops's horns up to the
Tyrannosaur's torso. If a Triceratops, or similar ceratopsid charged a
Did that a lot when little.
T. rex, its rostrum would -pass under- the Tyrannosaur's thorax, while
the full length of the orbital horns would be driven into the body,
potentially rupturing the heart or lungs. Once the full length of the
horns were plunged in to the body, the rostral horn may have further
lacerated the underbelly. What I see is a set of horns very well
"designed" to kill a large Tyrannosaurus. In fact this is now my next
art project: a charging Triceratops killing a T. rex : ) I'll get it
scanned into deviant art when I'm done and send you a link.
Well, the models I've seen on store shelves and pictures of remains
tend to show the horns diverging, not pointed directly ahead. I'm not
sure that both horns would be positioned to both pierce the body.
One thing that also occurs to me is if the rex/whatever were charging
or otherwise moving towards the triceratops, would those horns be able
to withstand the impact?
And as far as the rostral horn is concerned, it probably doesn't have
much of an edge, so considerable force might be needed for a similar
Just how well is a ceratopsid skull built to take impaces?
