Platypus Ancestor Found

When a platypus specimen was first viewed in England it was a sensation, Many people including scientists said that it was a fake: it was a combination of parts from other animals. However, it did exist in the Australian niche where it evolved.

I should be noted that this was in an era when the English were still struggling with Darwin's theory of survival of the fittest. The majority of the population still believed that God created Man. The Garden of Eden was foremost in their minds.

Today, the platypus' existence is accepted without question. There has not been a lot of fossil evidence about how it came to be. Recently, this gap has been filled by a fossil of an ancient duck-billed marine reptile. Like most fossils which illuminate family trees it was found in China.

Eohupehsuchus brevicollis lived 248 million years ago. Only two other examples of this creature have been brought to light, both in other parts of China. Like the platypus it was small for its time. It lived in an inland sea.

While its body proportions were different from the platypus, clear parallels can be seen: a broad body, no teeth and paddle arms for swimming. Eohupehsuchus brevicollis had a very short neck like the platypus. The fossil is an excellent specimen for research being nearly complete. It has evidence of being attacked, though it did survive this and lived for some time afterwards. The animal was a survivor of the mass extinction of the Permian era 252 million years ago.

Life Began on Land

Life may have begun on land not in the sea, Multicellular fossils, ancestors of marine life, lived on land. These were microbial colonies like lichen. Ediacaron fossils over 600 million years old have been found in South Australia.

High-tech investigative technology showed the ancient forebears lived on land. The soil they were in had "old elephant skin' over it. This phenomenon forms in sandstone beds. It is much like the surface of modern sandy deserts with close wavy lines.

Ediacaran fossils were direct ancestors of marine animals, not mammals. The chain of life leading to humans came during the Cambrian era long after these old multicellular fossils. Apparently, the presence of salt and even too much water are barriers to initial life formation. There was more animals diversity on land than in the sea during the Cambrian.

Sauropods Were Ideally Suited to Grow Large

The largest animals ever to roam the Earth were sauropod dinosaurs in the Jurassic and Cretaceous eras.  They did not eat meat.  Despite having to constantly eat grass and leaves the heaviest reached 50 tonnes.

The periods going back from the present are Cenozoic, Cretaceous, Jurassic, Triassic and Paleozoic.  The last four are grouped into the Mesozoic era.  It is in this general broad time frame that the gigantic dinosaur arose and died off.

Though for the most part these creatures walked with their heads in an horizontal position, for feeding it is presumed that they reached up vertically to feed on young branches and leaves high in the trees.  Other herbivores could not reached up to this rich food source.  Mammals had not yet risen.  Giraffes appeared much later.

Having plenty of food meant the sauropods could evolve and become very large.  Their bones were light and with a small head the neck became long.  They swallowed food whole so they had tiny jaw muscles.  Food remained in the body a long time.  This enabled thorough digestion of leaves and even some wood.  Not masticating in itself left more energy to grow bigger.

They were bird-like, having an efficient respiratory system; thus the significant body heat was dissipated.  The high basal metabolic rate meant they could live longer and survive to become adults and reproduce.  Having many young from eggs maintains a species more effectively than the mammalian way of breeding.
