Fossil Museum
After the formation of fossils, ancient creatures died, was quickly buried in the ground, the flesh and bone erosion soon disappeared, angle, teeth and other hardware part in a "fossilization", look into stone. At the same time, the original composition of the hardware has been replaced by the subsequent minerals. So the remains of ancient creatures become "fossils" ".
Fish fossils：
Fish's body, after hundreds of millions of years of change, and long-term isolation from the air, but also by the role of high temperature and high pressure, the body covered with mud and sand more and more thick, the pressure is also growing. After many years, the fish body above and below the sand into a solid sedimentary rocks, among these sedimentary rocks in the fish's body, has become a stone like things, and very hard, this is the "fish fossil".
Animal fossil Museum collection of four kinds of fish fossils are from Wuxi Wuxi, Liaoning Chaoyang hungry fish fossils of Lycoptera fossils, Hubei Songzi, Shandong Jianghan fish fossils from Shanwang fossil fish.
Yima ginkgo fossil:
In Yima Province, Henan Province, the Mesozoic plant fossils are distributed in the Mesozoic continental basin of Yima, Yima, Yima, as the representative of the ancient plant is one of the standard plant groups in East Asia to Europe and Asia. Study on the area of the Chinese Academy of Sciences Nanjing Institute of paleontology Zhou Zhiyan academicians and other experts at home and abroad in recent years, has established "Yima ginkgo" fossil flora, that "Yima ginkgo" is found so far the world's oldest fossil ginkgo. The output layer has been named as the "Ginkgo biloba" and has shocked the Chinese and foreign ancient plants. This area has become an important geological relic area which has a great influence on the protection of the area.
Brachiopod fossils:
Brachiopods scanty in today's oceans, in deep sea but only a small amount of brachiopods, extinction. But who can think in the past long geological time, they had flourished. Brachiopods and mussels (called Pelecypoda, a software animal has the same door) two shell, looks similar, but further observation, we can find not very like them. Brachiopods live only in the sea, visceral and wrist cavity in the shell, the wrist for cavity occupied by the wrist with a long and tough, pedicel shell to sessile, when the shell is opened, the cavity of wrist carpal cilia swaying, the sea has to flow through the cavity from the wrist, smoking the tiny plankton sea. Here the brachiopods are divided into five types, namely head shell, shell, the owl bow Shi Yan, room five, Bei athyris.
Coral fossils:
Stone pillars, coral jade. Common Coral fossils have two types of monomers and complex. Single coral skeletons, from a few millimeters to several centimeters, usually around the wall, decorated with different thicknesses surface wrinkles, but in the evolution of the advanced level of coral, wall degradation. Compound coral is massive body compact, or thin Arbuscular shape, composed of many small corals, some from the maternal axial or lateral bud out some through holes or pipe wall or coral, coral between monomers were bone or mutual contact gap tube. Coral skeletons skeleton of the body by numerous small calcite or aragonite needles, feather feather chemical composition.
Trilobite fossils:
The swallow stone, also called stone bat, called trilobite fossils. Trilobites (TRILONITES), an ancient arthropod animal, belonging to Insecta, born in the sea, the variety of sizes, from centimeters to a meter in the Cambrian to Ordovician (570 million years), (450 million) the most prosperous in the end of the Permian extinction. Trilobites are marine invertebrates, mainly benthic life, there are some living in the sediment and floating life, more than 10000 have been found in the world, more than 1000 have been found in china. Because the composition of insect chitin as back carapace, easy to store for fossils, because the carapace was two for the longitudinal axis of the back channel, and two symmetrical ribbed leaves, called trilobites. Into the head, chest and tail three parts from front to back, the insect can life stage shelling, so common in the head and tail of a preserved fossil.
Ammonite fossil:
Is about 200 million years ago, the marine invertebrate animals, is a benthic semi swimming life type, generally live in the shallow sea of 50 to 80 meters. It has a rich shell, shell wall thickness, beautiful appearance and so on. These fossils are found in Dongyuan Zeng Keng, a total of more than and 200, is currently the largest number, found the most abundant species, the largest ammonite fossil group, which has a 42 cm large ammonite fossil, southern crown. Due to the well preserved, the appearance of the strange, these fossils look more like a long in the stone of the chrysanthemum, the shape of lovely. Ammonite fossils are produced in shallow sea sedimentary strata, and symbiosis with many marine fossils
Maoming turtle fossil:
Maoming turtle is a freshwater turtle, a large shell, heart shape, bone plate thickness, the front end of the bone plate width is greater than the length, the front end of the central posterior fossa.
