If you have been thinking that Echidnas and long cousins were walking in their unique and waterways, and thought. One arm bone, found in the remote corner of Australia in Australia for the last decades, rewriting the same scientists – and perhaps changing what scientists knew how they allowed different places.
Both belong to Order Mononremata, a separate commandment of mammals that bear eggs instead of live offspring. The plattpus is busy these days to run with streams and streams, and Echidnas Firrow around the ground demands ants, termites and worms.
Scientists were believed to believe in the past for a few days to come down from the country that lived in the country, and platatypus were developed to eat water. But new discoveries show a different: Echidnas origins and platypes and it is likely to start at sea.

Fossil with a long Tand to tell
Findation was directed by the Unansw Sydney school of Biardo, and the world’s environment and the Kheritus Siza Professor Suzanne Hands and investigators. Fossil represents the unorally half of the upper left arm of the Kreryctive Cadbury. It is estimated that he lived 108 million years ago during the first cretaceous time when Dinosaurs ruled the world.
The 1990s Victoria Cleavators were found in Dinosaur Cove, the site that had been found in receiving long ago. The bone was considered to be like the echidna bone today, and some believed that it would be an ancestor of Echidna. Some believed that it would be a stemmaker, the old wooden relative and edidnas.
But it was not so that scientists decided to ignore its outer situation and look inside and use full scan strategies until they arrive. “When the external structure of the bone will help you to compare it directly to the same animals, the internal internal structure will usually express something about its life,” said his hand.
Inside the bone: the secrets of the past
In Humerus, researchers find features such as non-exported edidna. The bone consisted of strong walls with the smallest mammals – the features of professional animals such as platypus. Cramped bones play ballast work to allow animals to enter and remain underwater without breaking. Echidnas have luxurious bones that are eligible for excavating the earth.

Research explains Ukrseryctes Cadburki as a sharp digger and completely adapted to water and soil. That can elevate ancient Mononyreme life of ancient Mononyreme that considered scientists to become another way. If so, Echatna’s development and platy development began in the water and Echidnas appeared without water in the world completely in the world.
“Such a situation would be an unusual,” provinces, added some 30 mammals from the country, dolphins, Oters, said – there is changed.
MONTONTONKING MONONTORME history
Fossil also shows how the platypus has changed. Professor of Urso Professor Michael Archer and adds that the ranking of evolution has led to the modern platypus has shown “more than 100 million years, Echidnas is a way to depart from such a history of such water.
However, the remnant record of the Monotreme ancestors are limited. The teeth and teeth have a role of many Australian Mammal Mammal pillars. The Lim Bone Krseryctes Cadbury is the only one from that time, and provides scientists the unique opportunity to learn animal habits.
“The Cityu has given us a wonderful opportunity to find out about the Australian mammals and in the houses, and tell us the story – perhaps not trusted in hearing,” he said.

A sign of aquatic life in Echidnas
Echidnas is not swimming rivers as Plyypuses but keep her bodies with bleeding. First, their debt contains serious sensitive electrorecectors who take electal electal electals in happiness – such as Platypus bill. Perhaps the vestigial vestigial users of the archaic softening. Even the embryonic edidnas keep track of the weaknesses of this estate: Platypus traces such as payment such as Typonic.
Their legs are a view again. Echidnas, and platypuses, keeps background legs back, although they used to dig these days and not swim. The back foot is not uncommon to mammals outside monotres. Physiology also releases.
The Echidnas also has Diving Reflex – reducing the decrease in the heart and maintaining an oxygen during the conflict – the same with marine mammals. Myoglobin analysis, which measures the amount of alcoholic protein, reveals the Echidnas of the expected mammals, which show their ancestors have already depends on wider foods.
Technology changes in paleontology
As KreryCTTTER FOSSil is unusual, researchers can not simply connect it open to look at its microscopic shape, or history. Instead, they use the elevated methods, non-corrupt measures such as synchronotron imaging to study bone at lower case level.

Scientists hope that such technologies will reveal the growth patterns, physiology, and animal life without sacrificing glasses. This study is underway, and scientists also use their research on other Fossil beds such as Lightning Ridge in New South Wales. These beds have strongest mesozoic beds of monotremes, and can rebuild the missing links to the past evolution.
Why is it important
New information reflects not our knowledge of the evolution of the plattpus and edidna, but a common picture of how mammals are – or repent and repent of new countries. If Echidnas inherit the seafood, they are very young for mammals to make a marvelous geographical world for evolution.
It sets exciting questions about what opportunities and pressures have led to Echidnas in the country. Was it a food competition? Change of Weather? Or a combination of things? Besides many horns, answers remain unavailable. But one thing is clear: The story of these egg-eyed suppliers are far from completed.
From one ancient bone, we learn that life history is rarely a straight line. Evolution can take awesome, and sometimes, it is repentant.
Research findings are available online in Journal Pnas.
