Australian Marsupial which strangely lays eggs!! Looks like a cross between a duck, otter, Beaver. Also rare, it is a venmous mammal with poison spikes on its hind legs. Fossils date back 100,000 years. Related animal fossill 110 Million years old making it one of the oldest mammals. Fossils found in Argentina from 167 Million years ago when the earth had "super continent" linking it to Australia. Unique to only to east Australia {no Crocodiles} the genetic make up is incredible! Ten sex chromosomes compared to two in other mammals. Genome has signs of bird, mammal, reptile, amphibian, and fish??????
