Australia found that 500 million years ago, fossils of giant marine predators
University of Adelaide, South Australia cool gadgets , Australian Museum scientists have recently discovered in South Australia on Kangaroo Island, a 500 million years ago, fossils of giant marine predator-depth study found that only once at the top of the food chain early Earth giant marine predators actually has a very impressive sight. According to this important research artists drawn map of the animal's artistic imagination, and as scientists map the distribution of archaeological results published in a recent issue of "Nature" magazine on top.
Only the giant marine predators called "odd shrimp", even amazing body length of 10 meters, it was the Cambrian marine ecosystems the top predator, living in about 500 million years ago. Based on the fossils paleontologists study found that the odd exception shrimp preserved intact eyes. Early this Earth actually has a very sharp top predator eyes, their vision even more than the existing most insects and crustaceans vision. The finding that surprised scientists. The project team members include Michael - Dr. Lee, Jim - James and the University of New England, Dr. John - Dr. Patterson and others.
Often the odd man nightmares shrimp and science fiction film and television roles, it is because the body is huge and is considered the top of Earth's earliest food chain species. The powerful head has a long front claws of a giant, circular mouth has sharp teeth. As top predators of the fossil evidence from their new gadgets droppings, which contain the remains of trilobites contemporaries.
The scientists made one of the major achievements of Kangaroo Island in South Australia 515 million years ago, a layer of sediment excavated odd shrimp fossil found a outstanding handle eye, and this has complicated the eye of the handle optical structure. This extraordinary vision is also strong evidence of odd shrimp predation.
Fossils found on the compound eye is by far the largest of all living things found in the compound eyes, each eye is about 3 cm length, containing more than 16,000 small eyes. Small number of eyes and other optical characteristics are that odd shrimp has extraordinary vision, can be cloudy, dark accurate prey underwater. Today, only a few arthropods only have a similar structure.
In the Cambrian ecosystem, this extraordinary vision with the presence of predators, increased between the predator-prey "arms race", which is an important stage of early animal evolution. The discovery of odd shrimp compound eyes that powerful, it is a close relative of modern arthropods. At the same time, this finding also shows that this peculiar evolution of the visual organ in arthropods had already top gadgets appeared very early, and the structure is very fine, complex.
