SOURCE: At the Earth's Core by Edgar Rice Burroughs (All-Story Weekly, April 4-25, 1914)

DESCRIPTION:"And at the first glance there broke upon my horrified vision the most frightful thing I had seen even within Pellucidar. It was a giant dragon such as is pictured in the legends and fairy tales of earth folk. Its huge body must have measured forty feet in length, while the batlike wings that supported it in midair had a spread of fully thirty. Its gaping jaws were armed with long, sharp teeth, and its claw equipped with horrible talons..." (At the Earth's Core by Edgar Rice Burroughs)

NOTES: The thipdars are the pets of the Mahars. These pterodactyls would be better described as pterodons as they are much larger than a human.

HISTORY: Lin Carter would borrow these creatures for his Thongor series, calling them Grakks. Rachel Welch would borrow the nest scene from Tarzan at the Earth's Core for One Million Years B.C. You can't tell me Harryhausen isn't an ERB fan!
