His most widely recognized work is the creator-owned comic book series Xenozoic Tales, which describes a post-apocalyptic world where dinosaurs and other prehistoric creatures coexist with humans.
Four years later, after graduating with a Bachelor of Fine Arts degree in painting, he embarked upon a career in advertising illustration, bolstered by such odd jobs as working as a security guard, which he ultimately found unsatisfying.
The characters and stories he created were set in a future time period he dubbed the "Xenozoic Age", in which an unspecified cataclysm had all but wiped out modern human society.
The survivors emerged from their underground bunkers to find a world transformed, where prehistoric creatures had once again become the dominant life forms on Earth.
He was also interviewed by Durwin Talon for Panel Discussions, a nonfiction book about the developing movement in sequential art and narrative literature, along with, Will Eisner, Walter Simonson and Mike Mignola.
Also with the publisher, he contributed with other artists to the graphic novel Flesk Prime in 2011, and in 2015 Schultz released an illustrated pulp noir/science fantasy adventure novella Storms at Sea.
[11][12] In 2015, Schultz contributed, among other artists, to bring inner illustrations to the tabletop role-playing game Conan: Adventures in an Age Undreamed Of, first published in 2016 by British company Modiphius Entertainment.
