The name derives due to its location within South America, which during the Mesozoic Era was part of the supercontinent that was southern Gondwana. Many other hadrosaurs were found within the supercontinent that was northern Laurasia which is why it was not able to be separated from its fellow relatives. It was believed to be the sole hadrosaur found in Gondwana prior to the finding of Willinakaqe salitralensis , which was discovered in 2011.

The species of the type is Secernosaurus koerneri that was discovered in 1979. The species was named in 1984, Kritosaurus australis, is believed to be a synonym.
