The American Triassic mammals are known at present only from two small lower jaws, on which has been founded the genus Dromotherium, supposed to be related to the insect-eating myrmecobius, now living in Australia.

Its nearest living analogue, says Professor Owen, "is found in myrmecobius; for each ramus of the lower jaw contained ten small molars in a continuous series, one canine, and three conical incisors- the latter being divided by short intervals."

Still older than the above are some fossil quadrupeds of small size, found in the Upper Trias of Stuttgart in Germany, and more lately by Mr. C. Moore in beds of corresponding age near Frome, which are also of a very low grade, like the living myrmecobius of Australia.
