I recall some maps from classic dinosaur books such as The Lost World by Sir Arthur Conan Doyle and The Land That Time Forgot by Edgar Rice Burroughs. These maps were hand drawn as though they were drawn by a survivor who saw these primeval worlds firsthand. I may not be good at drawing creatures or characters, but I am good at drawing something of this quality. Due to this, I think I might do a map of the artificial island that my dinosaur book takes place on. I will draw it in the same fashion as a castaway would draw the island they were stranded on.
