In this case the fossil record confirms what we can deduce equally well from the
outgroup criterion , since the multipletoed condition is general among the orders
of mammals . In contrast , the Litopterna , an extinct order of South American ...

Late in the Triassic , at about the same time as the first dinosaurs evolved , some
of the therapsids — the mammal - like reptiles that had arisen in the Permian -
approached the mammalian condition so closely that some of them are
considered ...
