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.

Woodside Petroleum Will Destroy Dinosaur Footprints

Ancient dinosaur tracks may be destroyed by gas companies moving into the Kimberleys. In the Dampier Peninsula near Broome more than 15 different kinds of dinosaurs foot prints are "embedded" into the landscape. They are in 130-million-year-old sandstone.

Woodside plans to open up the area for natural gas development. Just bringing people there opens up the tracks to damage. Arguments are raging all over Australia at the moment between natural gas companies and farmers who fear damage to their pasture from polluting chemicals used in the search process. Companies can just open a farm gate, drive in and start drilling - no permission is needed.

New dinosaur footprints are being found at the Kimberley site, notably of the very large sauropods nearly a meter in diameter. The varied prints are in different layers. They have been laid down over an extended period of time.

Woodside is saying better quality tracks are found well away from their intended development and losing some footprints is unimportant. The company is obviously ignorant about scientific research. All finds in relation to dinosaurs are important.
