Self-preservation, or impressions in sedimentary rocks, or traces left by survival (called trace fossils). Fossils, usually animals and plants, are buried by water-bearing sediments soon after death, causing chemical reactions, and then adding minerals or expelling organisms. If this process does not happen, the organic experience will be preserved temporarily, but it will not become a fossil.
Fossil collection is a fascinating hobby. In recent decades, more and more people have joined this activity. Its charm lies in that collectors can not only enjoy the excitement of discovering fossils, but also master the operational skills of collecting and making specimens, and also have the academic challenge of identifying fossil discoveries. Few other sciences enable beginners to make such an important contribution to prehistoric historical knowledge as fossil collection.
19 10, Sir robert Falcon scott began his historic but tragic expedition to the South Pole. Scott
The four partners eventually became victims of bad weather, but left important scientific discoveries. Found in the explorer's belongings.
Fossil seed ferns, ferns. This discovery proves that the frozen Antarctic was once a part of the fertile continent;
At the same time, it can be inferred that Scott understands the scientific importance of his discovery. From coins to bones, "fossil" comes from Latin fossil, which means "excavated" and refers to anything buried. There are not only fossilized animal and plant residues, but also rocks, ores and artifacts, such as coins.
Now, the word refers to the biological remains that existed in prehistoric times but were buried and preserved by nature. Greek philosophers who have been fascinated for many years believe that fossils are very strange natural phenomena, just like crystals and stalactites, which are formed underground. Martin Luther (1483/U 1546) believed that the fossils found on the mountain peaks were evidence of blood in the Bible. Da Vinci (1452 ~ 15 19) wrote in his notes: fossils are the fossil remains of creatures that once lived. His views were regarded as heresy at that time until 19.
Ji, his notes were made public.
The real fossil mask was not known until17-18th century, which was mainly due to the publication of fossil collection books and people's understanding of nature.
Learn more about history. People have discovered an important fact that different kinds of rocks contain different kinds of fossils, which is very helpful for making the first geological map, and thus created two modern sciences: fossil science and stratigraphy.
classify
When people mention fossils, they always use a two-part scientific name, although it is informal or common. For example, oysters are often called "devil's toenails" in Latin, and brachiopods are called "lamp shells". These all have their own.
Useful, but lacking the accuracy needed by science. Scientific names are usually written in italics, followed by the name of the discoverer (the person who first described the fossil). The first part is genus, and the second part is species. If people's names are found in brackets, it means that the species is divided into other different genera when it is used.
The scientific name only refers to a single type of organism, which can be understood by scientists all over the world. The basic unit of classification is species, and all members of a species are basically similar and can cross each other. One or more species are composed of them.
Some features are interconnected to form a genus. Genealogy or genealogy of an organism consisting of families (a group of genera) and orders (a group of families). The names of the following species are artificial classifications, which constantly change with the changes of views in different periods.
Purpose and limitation
This book expounds from ordinary fossils to unusual but spectacular fossils to help collectors. These fossils are selected from the largest and most widely collected museum in the world-London Natural Museum. Although many fossils are fascinating, they are right.
Their research work is very professional. From worms to dinosaurs, from ammonites to humans, from all geological ages to all continents, most fossils are included in this book. The description of each fossil is written by many different types of fossil research experts, and the technical terms are minimized. Many fossils are difficult to find completely, especially large reptiles and mammals. In this case, this book only expounds a small part of bones. It is impossible to photograph every fossil. However, the range and types of specimens in the book
Class is enough for collectors to draw inferences, find out the closest photos and descriptions, and conduct preliminary identification.
