Cynodontia: a little history
Cynodontia are therapsids that first appeared in the Late Permian (approximately 260 Ma). The group includes modern mammals (including humans)
as well as their extinct ancestors and close relatives. Nonmammalian cynodonts spread throughout southern
Gondwana and are represented by fossils from South America, Africa, India, and Antarctica. In the northern continents,
fossils have been found in eastern North America as well as in Belgium and northwestern France. Cynodontia is one of the most diverse groups of therapsids.
Roy G. Krenkel, Hugo Award Winner, master penciler, iconic illustrator, cover and interior artist of many greats: perhaps most notably, the ‘second wave’ 1960s revival of Edgar Rice Burroughs’ stories. Born in the Bronx, his studies in art were interrupted by service in WWII. Upon his return to NYC, he dove back into art classes, under tutelage of Burne Hogarth, and by the 1950s found himself illustrating for comic book publishers and pulp publications. Ace editor Donald Wolheim was struck by Krenkel’s style in Burrough’s fan publications such as Amra and ERBdom, where he found an evocative style reminiscent of the great J. Allen St. John. The 1962 At the Earth’s Core and The Moon Maid, Krenkel’s first for Ace, were instant successes. Despite this, Krenkel felt pressured to continue this echo of St. John in further work, though he did not succumb to mimicry, continuing to express his unique line and style in his Ace work for Wolheim, his Canaveral hardcover releases, and countless works for fanzines and fans alike.
