A giant temnospondyl, an ancient amphibian, was discovered from an Antarctic fossil originally found in 1986. Named Kryostega collinsoni, the salamander-like amphibian was 15 feet long and had an unusual set of teeth. The teeth found on the palate of the salamander were found to be longer and thicker (1.6 inches long/.5 inches wide) than the teeth at the edge of the mouth (1.2 inches long/1 inch wide) .
