are platypus the only mammals that lay eggs
Platypus The platypus (Ornithorhynchus anatinus), sometimes referred to as the duck-billed platypus, is a semiaquatic egg-laying mammal endemic to eastern Australia, including Tasmania. Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth. The animal is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species have been found in the fossil record. The first preserved platypus body was thought to have been a fake, made of several animals sewn together,[3] when it was first looked at by scientists in 1799.[4]
Aegyptopithecus Aegyptopithecus zeuxis has become one of the best known extinct primates based on craniodental and postcranial remains.[2]
