Nothin’ like a little humor to spice up a scientific illustration. Humans are often pictured for scale in dinosaur reconstructions like this, but I’ve never seen one kickin’ it with so much ‘tude. I like it.
This illustration appears to be done by Mike Taylor, although on his blog he asks, somewhat confusingly, that the image be credited to Scott Hartman. His words:
The skeletal reconstruction was executed by Mike Taylor based on a reconstruction of Camarasaurus by Scott Hartman, and may be freely reproduced so long as Hartman is credited.
