Cretaceous Blue Moon, by Robert Nicholls | Tumblr | Facebook.
"By the light of the moon a spectacular annual gathering of Elasmosaurus platyurus takes place. Their courtship requires them to raise their long necks high out of the water to display their strength and suitability for mating. Remarkably the elasmosaurs chose this particular time and place because it coincides with a seasonal bloom of bioluminescent plankton, which make them glow blue.
I first sketched this idea in 2006-2007ish. I would like to be able to say this is the first artwork illustrating _Elasmosaurus_ using their necks this way but I was too slow to producing this image and the brilliant John Conway beat me to it. Nevertheless, the composition is completely unique and I am pretty sure a bioluminescent gathering is a first in the world of paleoart!”
