That is, Echidna has developed around 52 million years ago Tyrannosaurus.Echidna then survived whatever killed the dinosaurs and lived another 65 million years to the present.

This does not mean that Echidna is evolved at this time, but suggests that the basic shape has been successful in significantly different terms. Echidnas live up to 45 years. They can grow to about 6 years. Studies on Kangaroo Island indicate that they only breed every three to seven years, so the Echidna is a prolific breeder.
