Exempel på hur man kan använda ASTRAPOTHERES i en mening

• Its endemic mammals initially consisted primarily of metatherians (marsupials and sparassodonts), xenarthrans, and a diverse group of native ungulates known as the Meridiungulata: notoungulates (the "southern ungulates"), litopterns, astrapotheres, pyrotheres and xenungulates.
• Though most SANUs lived in South America, astrapotheres and litopterns are known from Eocene aged deposits in the Antarctic Peninsula and the notoungulate Mixotoxodon spread as far north as what is now Texas during the Pleistocene as part of the Great American Biotic Interchange.
• Postcranially, astrapotheres are relatively robust and more or less graviportal but have slender long bones, most notably in the hindlegs, suggesting they were amphibious.
• A redescription of the skull anatomy of the holotype specimen of Eoastrapostylops riolorense, with an emphasis on the auditory region, is published by Kramarz, Bond & Rougier (2017), who interpret this species as a member of a basal meridiungulate lineage that diverged before the differentiation among astrapotheres, pyrotheres and notoungulates.
• The herbivorous fauna was completed by various meridiungulates, such as astrapotheres, Pyrotherium, the proterotheriid (or possibly didolodontid) Salladolodus, the macraucheniid Coniopternium, the adianthids.
• Those researches would indicate that Eoastrapostylops was one of the most basal member of the South American ungulates, and differentiated before the separation between astrapotheres, pyrothere and notoungulates.
• The diverse fauna of the Sarmiento Formation, including a variety of birds, crocodilians, turtles and snakes, also includes many mammals such as South American native ungulates (notoungulates, litopterns, astrapotheres) as well as armadillos, and caviomorph rodents.
• The diverse fauna of the Cerro Bandera Formation include a variety of turtles and birds, also includes many mammals such as South American native ungulates (notoungulates, litopterns, astrapotheres) as well as armadillos, and caviomorph rodents.
