As Fowler and his colleagues examined the various types of bite mark on the skulls, they were intrigued by the extensive puncture and pull marks on the neck frills on some of the specimens. At first, this seemed to make no sense. “The frill would have been mostly bone and keratin,” says Fowler. “Not much to eat there.” The pulling action and the presence of deep parallel grooves led the team to realise that these marks were probably not indicative of actual eating, but repositioning of the prey. The scientists suggest that the frills were in the way of Tyrannosaurus as it was trying to get at the nutrient-rich neck muscles.
“It’s gruesome, but the easiest way to do this was to pull the head off,” explains Fowler with a grin. The researchers found further evidence to support this idea when they examined the Triceratops occipital condyles — the ball-socket head–neck joint — and found tooth marks there too. Such marks could only have been made if the animal had been decapitated.

Okay, grabbed my sister’s Nikon and these WIP shots came out much better. The color is still a bit dodgy, but the clarity is way better. The best representation of color for Mr. Triceratops is in the picture of my “workspace” —my mom’s kitchen table is my current substitute for my desk. Gah. Anyway, hope these look better. This should be finished tonight or tomorrow.

Final sketch of a Triceratops for a Tumblr friend’s new blog about dinosaur problems. Gonna color it in tomorrow (at least half of it hopefully) and then it’ll be finished for her the middle of this week.
I’ve been chomping at the bit to post a sketch, so here it is. WIPs and the final soon to come (if she’s okay with me posting those). :)
By the way, that dark business going on isn’t going to be there for long. I had to print my sketch on a piece of printer paper and then I went over it because I ran out of space in my sketchbook. I know it looks kind of derpy.
Triceratops by Charles R. Knight.
“Charles R. Knight (1874-1953) may be the most famous of all paleontological illustrators. This painting of the museum’s Triceratops was commissioned by the Smithsonian and completed in 1901. In 1905, the Smithsonian Institution mounted the world’s first skeletal reconstruction of Triceratops for exhibition. The mount was a composite of sixteen individual skeletons of Triceratops as no single skeleton was complete. This painting received a USNM catalog number, usually reserved only for the specimen collection.”
