Input: Question: Which of the periods in which Thalassocnus lived lasted longer? Passage:Thalassocnus were ground sloths that lived from the Late Miocene to the end of the Pliocene—Late Huayquerian to Early Uquian in the SALMA classification—and all five species were discovered in different horizons of the Pisco Formation in Peru. T antiquus was discovered in the Aguada de Lomas Horizon in 7 or 8 million year old strata; T. natans (the type species) from the Montemar Horizon lived around 6 million years ago (mya); T. littoralis from the Sud-Sacaco Horizon lived around 5 mya; T. carolomartini from the Sacaco Horizon lived between 3 and 4 mya; and T. yaucensis from the Yuaca Horizon lived 3 to 1.5 mya. Specimens were also found in the Bahía Inglesa Formation, the Coquimbo Formation, and the Horcón Formation in Chile. At total of three species has been identified with certainty in Chilean formations, T. carolomartini, T. natans, T. Antiquus while the presence of T. yaucensis is judged likely.
