Body Fossils and Trace Fossils

If this process does not take place slowly, the original hard parts lose all the traces of the original structure and the original shape remains, but there is no detail (virtual). Calcification is the most common form of fossilization of dinosaur bones. This occurs when the groundwater carrying the dissolved mineral penetrates the pores and cavities of bones, trees, or shells (K). The mineral then still produces a stone fossil that contains most of the original solid material. Let's save bones, teeth, and marine life in this way.

Body fossils and trace fossils are evidence of the main kinds of ancient life, geochemical evidence serves to break the evolution of life and there are creatures large enough to leave fossils in the body I will. Estimating the dates of these will is necessary but difficult, sometimes the adjacent rock formations allow radiometric dating to provide absolute days with 0.5% accuracy, but more generally paleontologists say "puzzles" If you do not solve the problem of stratigraphy by "Relative dating" Classification of ancient organisms because it is not suitable for the linna taxonomy commonly used to classify paleontology It is also difficult. Molecular phylogeny was discovered in the last quarter of the 20th century. And it examined the relevance of the graduated purpose by measuring the DNA similarity in the genome.

Traces of fossil remains and ancient life. There are various kinds of fossils. Dinosaur bones and other body parts are called "body fossils". Things like footprints are called "traces of fossils". Fossil specimens of dinosaurs are also fossils. Fossilization

Trace stones (or fossil canines known in the art) are fossils that capture biological activities or behaviors. The best known trace fossil version is the footprint, but there are many other fossils. Other common examples are cave, bite mark, drill trace and fogolite. When classifying trace fossils by name, paleontologists use allogeneic and species systems of other types of fossils we know familiarly. But the difference is that trace fossils are not unique to the species from which they are produced. For example, some forms of all vertical tubular structures belong to the genus Skolithos, regardless of the animal from which they are made.
