Biologists have discovered an oviparous mammal that was considered extinct (2 photos)
No one has seen the long-beaked echidna for 60 years. 
Members of the international scientific expedition Expedition Cyclops accidentally discovered a living Attenborough echidna. The oviparous mammal lives on the Indonesian island of New Guinea. The unusual find is reported on the project’s official website.
Biologists said that the echidna was seen only once in 1961. Then she was named after the famous British TV presenter and naturalist David Attenborough. From that time on, no one ever saw these creatures again. 
Until recently, many biologists doubted the existence of this echidna. But experts were able to prove that Attenborough's echidna exists. Experts placed cameras in mountain forests for four weeks, but could not find any traces of the animal. But on the last day of their stay, the elusive animal was finally captured in the photographs.
Attenborough's echidna has the spines of a hedgehog, the snout of an anteater and the paws of a mole. The reason the echidna is so different from other mammals is that it belongs to monotremes, a group of oviparous individuals that split from the general tree of mammal life about 200 million years ago, the head of the expedition explained to the BBC.
