Fighting apatosaur art #1: Brian Engh
September 19, 2015
In putting together our thoughts on how apatosaurs used their necks, we were motivated by genuine curiosity — which in Matt’s and my case, at least, goes back many years. (We briefly discussed the problem, if only to throw our hands up in despair, in our 2013 neck-anatomy paper.) We didn’t land on the combat hypothesis because it’s cool, but because it’s where the evidence points.
That said, it is cool.
Brian Engh is on the authorship for this paper largely because of his insights into extant animal behaviour. But there’s no denying that it’s a real bonus that he’s also an awesome artist. He’s been putting together sketches to illustrate our hypothesis for some time, partly with the goal of figuring out which compositions to work up into finished pieces. Here, with Brian’s permission, are some of those preliminary sketches.
First, a really nice sketch showing a ventral-to-ventral shoving match from down at ground level.
I really like this one, and would have been happy for it to be one of the anointed ones. I like the sense of huge beasts towering over the viewer. That said, I always love pencil sketches, often more than I do finished pieces, so I’m not too unhappy that the world gets to see this one in pencil-sketch form.
Next up, sketched more roughly, is a concept for a different form of combat in a different aspect. Here, we see two animals side by side, wrestling with both necks and tails.
I like the dynamism of this one, and especially that the one on the right is in the process of being pushed over. But there’s nothing in apatosaur tail morphology that particularly says “combat”, so I guess I’m not too unhappy that this one didn’t make the cut.
The third sketch shows two individuals rearing into into ventral-to-ventral push.
Matt and Brian liked this one the most, so it got worked up into a finished and coloured piece which will be one of the figures in the paper when we get around to submitting it. Here is the current version — as I understand it, Brian plans to revise it further before it’s done.
The craftsmanship here is superb, but I can’t help regretting that the dinosaurs are rearing less than in the sketch. I feel it’s lost some of the power of the concept sketch.
What you’re seeing here, folks, is a bona fide instance of co-authors disagreeing. Happens all the time, but you usually don’t see it, because it’s all resolved by the time the paper is submitted. Brian is the artist, and ultimately it’s for him to decide what to depict and how; but I’ll always be glad that we still have the pencil-sketch as well as the finished version.
