Hyloidea
Scientists say the first Hyloidea animals evolved on the Gondwanan supercontinent in what is now southern South America, then spread throughout the world. Today, they live on every continent except Antarctica. In 2020, scientists found a fossilized animal that was roughly 40 million year old. The animal was from the hyloid family Calyptocephalellidae, and the fossil was found on Seymour Island in the Antarctic Peninsula. The distribution of Hyloidea species is highly correlated with climate, with most species found in areas with higher annual mean temperatures.
