FOSSIL ‘AQUARIUM’ PREHISTORIC ANIMALS
Excavating layers of limestone on the shore of the White Sea, 100
kilometres north of Archangel, Soviet scientists have found what they describe
as a unique "aquarium" of an underwater world six hundred million уеаrs old.
There are plates of rock made tip of numerous imprints and stone caste of
ancient multicell animals such as jellyfish, polyps, flat worms and other
organisms from fifty centimetres down to several millimetres. Many of them
were hitherto unknown to paleontologists.
This is the largest find of animal fossils from the pre-Cambrian era in the
Earth's geological history in the Northern Hemisphere. At that time, the
invertebrate ancestors of present-day animals were to be found only in the seas,
as they did not dare to explore the land.
The size and variety of species of the natural paleontological preserve in
the White Sea are comparable to the famous surface rocks from the same era
found in southern Australia, which are regarded as a model. A comparative
analysis of the Australian and White Sea prehistoric fauna has established
complete identity between more than a dozen organisms found in geographical
spots remote from one another. The experts see this as evidence that the
biological evolution was similar in opposite parts of the globe, that quite
possibly there was an open sea between them,and that there were more uniform
climatic conditions throughout the planet.

DEATH OF THE DINOSAUR
Dinosaurs have been extinct for about 65 million years. Interest in
dinosaurs, though never seems to die. People are constantly coming up with new
