In 1971, two fossil platypus teeth were discovered in the Tirari Desert in South Australia. They are about 25 million years old, and have been named Obdurodon insignis. The modern platypus has only vestigial teeth which are replaced by horny pads when it is still a juvenile. The fossil teeth are similar enough to these vestigial teeth to allow identification, and they show that ancient platypuses had teeth as adults.
The above is totally laughable - from 2 teeth they determine the characteristics of an animal that does not have any teeth! When I say that paleontology is a fraud, this is what I speak about.
I rest my case, at least for tonight.
