And living things need to struggle to survive. Later, the temperature rises, and the creatures have to re-adapt to the warm climate. This climate change eventually led to the disappearance of about 70% of species. … Fortunately, many creatures have survived, including trilobites and some primitive bony fishes that became the ancestors of today's vertebrates. Prehistoric_10 Trilobites escaped the first two mass extinctions, but unfortunately disappeared without a trace in the torrent of time. The Rise and Fall of the Fish Kingdom Time came to 370 million years ago, and the primitive bony fish continued to evolve and built a prominent fish kingdom.

Their king is a placode called Dunkleosteus. The largest one is 6 meters long and weighs up to 1 ton. It is the top predator, and everyone photo color correction services avoids it. Prehistoric_11 The 6-meter-long, 1-ton Dunn's fish was the leader of the fish kingdom 370 million years ago. At the same time, the plants on the land began to develop high into the sky, forming vast forests. The roots of the tree penetrate deep into the rock formation, destroying its surface, and nutrients are released from the rock and flow into the sea to become feed for the algae, which causes the oceans to lack oxygen and cause the extinction of a large number of marine life.

The best way to avoid the risk of oxygen starvation in the ocean is to draw oxygen from the atmosphere in shallow water or on land. At that time, there was already a fish called Tiktaalik, which developed lungs and strong fins, and started the Long March to invade the mainland. Prehistoric_1 Tiktaalik can breathe with lungs and have strong fins, taking land resources from the sea. The largest mass extinction event in history 250 million years ago, creatures have undergone hundreds of millions of years of evolution, and both the land and the ocean are full of exotic animals. There are some giant iguanas on land that have a.
