"Tour" is probably too grand a word for the scale of this comic, but while researching what was or was not plausible for this story (I know, really that all went out the window with the talking Thrinaxodon. But whatever.) I learned a lot about life in the Early Triassic. Readers also helped with many details, such as the fact that grass didn't appear until as recently as 65 million years ago. Trying to find a suitably scary predator for the time period also took a bit of stretching and speculation. But in the end, I hope the results outweigh the pinpoint accuracy of the subject matter.
