Ancient biology, the branch of geology, paleontology has classified into categories similar to biology. However, this report is divided into groups of fossils. Following the formation of the remains that were found in Thailand. I will not go into detail on the classification of a family name
common fossils found there are two main ways that fossil traces (trace fossils) with fossils that body (body fossils) Both patterns are. a whole different side to the generator. And maintains the characteristics of the carcass. And often co-occur at the same grouping, fossil addition to the reference shape. Sameness Or similarity of the remains found. Have a relationship of carcasses. Or evolution of the remains of style. And the environment in the area where the remains were found with
traces 1. fossils are the remains means that the activity of organisms that live in the area is mostly seen as a clue. Not a bone or schemes such as hallways or footprints (tracks) of organisms. Or may be a vestige of something else from the lives of animals in the past, such as bite nibble slots or holes in the housing nests and eggs of animals during feeding (feeding burrow), etc. In addition, the value of animals (coprolites), including stone animals. or to aid digestion (Gastroliths) is a fossil found in Thailand as well as vestigial traces of such fossils in sedimentary rock types. These marks must be interpreted as any kind of animal. Some species can not be used to determine age. But to tell the environment in the past as well as wormholes and sea shells of some species living room, etc.
2. The fossil's shape. There are many kinds of
small fossils 2.1. Thailand has many small fossils dating. As well as the environment in sedimentation of rocks as well. Some of these ruins can be seen with the naked eye. But some of it invisible to the naked eye. However, a small study fossils studied through a microscope. These are the remains of dead plants and animals is often a part of the plant pollen. The hard shell Resistant to erosion, decay. Pollen of plants to indicate the nature of the climate and geography primeval better identification of age. Because you can be blown away with the wind To accumulate in areas far from the source of origin. Most of it is used in conjunction with the plant during the new carbon Fe from 355 million years
for the remains of a small animal. Most are single-celled organisms. A hard shell wrapped You can maintain the remains of the stone floor as they mold Radio Maria. The diatoms are unicellular algae. And a silica shell. These enclosures on deposits very long time, it hardens packed a lot into a rock called Adaataamts (diatomite or diatomaceous earth) Adaataamts handy to use as a filter in distillate made of lime and ceramics are very common. Lampang
In addition, the remains small. The major one in Thailand is fusion Sullivan bit, also known as "Khot News" is a single-cell animal that looks like a slender grain. Used as index fossils Of the Carboniferous Fe at the end. The Permian era (about 355-250 million years ago) are found in limestone. Ratchaburi, Saraburi province, also found in other provinces as well,
2.2 fossils of plants. Plants are living organisms that have a long history. Since the beginning of the world in the Precambrian. The fossils of cyanobacteria. Until about four hundred million years ago. Most plants on Earth is still the algae in the water. Fossils of algae is very rare. Except for those who are clustering. And an outline of calcium carbonate. Later, on land plants evolved and changed shape, both external and internal to the environment on land, with the development of vascular and solid wood. A strong framework Proper sustenance on land
from these developments. The plant has spread out into the environment on land that occur on Earth. Since the Silurian (about 435 million years), the plant will initially be at the head of a branch no later leaves are fern plants occur. Followed by crops like palm and pine species by angiosperm was rising. Other
fossils of plants found in the rock. With nearly all parts of the plant stems, branches and leaves are often found in rocks accumulated in acidic environments, such as in stone, clay and shale, and often the processes associated with the coal. The coal mines of Thailand It is possible to find fossils of plants as well. In addition, it may be found in the sandstone humus. And often found the trunk, which is caused by the mineral solution penetrates into the tissue of the tree. That fell down slowly until it eventually permeates the entire tree. When it hardens into a rock called petrified wood (petrified wood), which in the age of petrified wood is found in the 200-65 million years (with the chain Ignatius) in Korat Plateau. And southern Thailand
2.3 Fossils of invertebrates Invertebrate fossils are the most common. Because this species has a hard shell. The same group density And in the right environment to the fossil while deaths
fossils of invertebrates is developing a sequel to the 3500 million years, until it starts to look like depictions of the Cambrian (545 million years ago) as a sponge. jellyfish and corals in all these animals. Jellyfish fossils are exposed to very little. But fossil corals are mainly found. In addition, they found creatures are protozoa that live in the ocean and lived in a group. Which ranged from four hundred million years ago to the present shell lamps or brachiopod. A sea shell with a cap lid does not equal two. Many species fossils found A range in age from 545 million years to the present. But some of the remains of a dominant era carbs.
