Paleozoic Archives: Cambrian Chapter

This work records 100 species of Cambrian creatures and is rich in content Cambrian: In the ocean 500 million years ago, a group of monsters lived Five hundred million years ago, the Earth was not what you see now. No humans, no dinosaurs, no life of any kind on land. The entire earth is covered by the ocean, and in that dark water, there are some creatures that you can't even imagine - Anomalocaris, the apex predator of the Cambrian period. It has sixteen thousand eyes and can clearly see the outline of prey several meters away. Its mouth is like a meat grinder, composed of thirty-two bone fragments. It ruled the oceans for tens of millions of years and then disappeared completely. Hurd shrimp has a huge hollow head that takes up half of its body. It took scientists a hundred years to figure out what it looked like - because its body was broken into pieces and scattered in museums around the world, each with a different name. The monster holding bug has a pair of extra-long spikes on its front appendages, which are specially used to pierce the abdomen of trilobites. It is the earliest armor-piercing weapon in the history of evolution. There are also weird bugs, obababin sea scorpions, pickup bugs, Kunming fish... Each of them actually existed. Each has its own survival strategies, hunting methods, and deadly weapons. They lived on this planet for tens of millions of years, and then they all turned into fossils, turned into stone, and became specimens in museum display cases. Five hundred million years later, their story is being retold. This is not a textbook, nor is it a compilation of papers. This is an in-depth tour of the Cambrian ocean—plunging into the dark waters of 500 million years ago to see how those monsters swam, ate, and lived.
