The echidnas have no fossil record older than the Pleistocene, but a fossil platypus, Obdurodon, is known from the Miocene and in the early 1990s teeth of an undoubted platypus-like form, Monotrematum sudamericanum, were discovered in Palaeocene deposits in Patagonia. The size and eating habits of the new species were later determined from a detailed study of the size, shape and function of the tooth, which is yet to be dated definitively. [2][3], According to Pascual, "The preserved enamel in the central region shows that the crown pattern is almost identical to that of Obdurodon: it is composed of two V-shaped lobes, the anterior of which is wider, separated from the posterior one by a valley that connects the lingual and buccal sides of the crown separating the anterior and posterior lobes.
