Dinosaur Hunter

Dinosaur Hunter

The Mesozoic Era begins at the end of the Permian. Eliminated the largest mass extinction of species of life that had existed during the Paleozoic era.

Continents

At the end of the Paleozoic Era the land that would become the continents of Europe and Asia has crashed in North America. At the time of the Mesozoic Era Pangea the super continent had formed.

Climate During the Mesozoic

Temperatures in the earth and sea, were much higher than during the Palaeozoic and tropical climates are more in nature. Despite this, the sea was lower, leaving different types of land masses to the process of life. In the Mesozoic was drier than in the Paleozoic Era. There was more desert and swamp less.

Retrieves the life of the Permian extinctions

It took most of first and second periods of the Mesozoic, the Triassic and Jurassic, the diversity of the species to recover and achieve some balance. While plant species had survived a little better than the animals over the Permian extinction, new types of plants developed to survive the changing conditions.

The warmer drier conditions of the Mesozoic era requires new methods of plant reproduction. Ferns and gymnosperms developed. Their methods of reproduction allowed for good protection of the spores or seeds that go through periods of drought, then an increase in child plant.

Marine Life

The survivors of the Permian there was very little competition. Corals, mollusks and fish dominated life in the oceans. Some reptiles are immersed in the water to become the first air to breathe in the ocean hunters. They took on a variety of shapes and reached the top of the food chain.

The increase of the reptiles and dinosaurs

The dominant land animals at the end of the Permian is synapsids. This group of animals is characterized by having a single hole on each side of the skull behind the eye. They are sometimes called mammal like reptiles. This group has almost completely disappeared in the Late Permian.

The animals that have developed new needs Mesozoic body types to survive extreme conditions of temperature and humidity. Amphibians developed respiratory mechanisms they can live inside or outside the water for long periods of time. But this age of reptiles that are better adapted to hot dry conditions. They have developed a skin thick and sometimes takes his own body and their eggs. The reptiles thrived, dominating the landscape in size and number. They are known as Diapsida. Diapsida are characterized by two openings on each side of the skull behind the eyes.

The dinosaurs have evolved from these reptiles and were themselves Diapsida. During the Jurassic and Cretaceous dinosaurs ruled the earth.

Ends Mesozoic mass extinction was

Another mass extinction occurred at the end of the Cretaceous, ending the dinosaurs and many other species. Although this event does not coincide with the end-Permian in the destruction of life is the second most devastating in the fossil record. It is generally believed an asteroid impact was the cause of this event.
