One of my friends did. She wrote it with classmates of hers when she spent one semester abroad in Sweden. She then got to play a dinosaur who was singing and pooping precious coprolites.
Sadly the video's on private.
I wrote a paper a few months ago on H. sapiens migration to and diffusion within North America based on coprolitic evidence. One of my sources (below) used parasite egg count as a health indicator, providing me many a chortle at the thought of those dedicated archaeologists sifting through turds:

We know they could. Parasaurolophus being the prime example... but most hadrosaurs and sauropods had very advanced vocal chambers. It most likely would be deep rumblings or honks, sort of like whales singing or dolphins chirping (not the uber high pitched echo location, just the happy audible squeaks)...

By the way I couldn't find your paper but it sounds really interesting!
