well yes but they do not sink in time so for that to work it is no such thing ok so dont worry if it can sink it can acshawel happen with cemecals and efectionsss.
it is called a paleontoligist. curtis
Paleoanthropologists study the development and culture of early hominids. They investigate the evolution of humans and their ancestors through the analysis of fossils, artifacts, and other archaeological evidence to understand the biological, social, and adaptive changes that occurred over time.
Hominoid fossils are the remains of primates that are part of the superfamily Hominoidea, which includes humans, great apes, and gibbons. These fossils provide valuable information about the evolution and behavior of early hominoids and help researchers understand the ancestry of modern humans.
Fossils of Homo erectus have been found in Africa, Asia, and Europe. The distribution of these fossils suggests that Homo erectus had a wide geographic range and was able to adapt to different environments. This indicates that Homo erectus was a successful and widespread early human species.
Biological anthropology is the study of humans and how they developed over time and space (evolution with backed proof of fossils), while Archeology is the study of material culture. Examples of this would include artifacts dug up such as stone tools.

Fossils are the results of the degradation of the organic material - chemical processes.
Fossils can change due to a variety of reasons such as erosion, pressure, and chemical reactions. Over time, the original organic material may be replaced by minerals, leading to changes in composition. Factors like temperature and moisture levels in the environment can also contribute to fossil alteration.
fossils
A limestone that contains fossils would be classified as an organic sedimentary rock because the fossils are of biological origin.
Fossils are evidence of biological evolution because they provide a record of past life forms, showing the progression of species over time. By studying fossils, scientists can trace the development and diversity of organisms, providing insight into how species have evolved and adapted to changing environments.
The four main ways a fossil can be destroyed once it has formed are physical weathering, chemical weathering, biological processes, and human activities. Physical weathering includes processes like erosion and abrasion that break down the fossil physically. Chemical weathering involves reactions with water, acids, or other substances that deteriorate the fossil's composition. Biological processes such as root growth or burrowing organisms can disrupt or destroy fossils, while human activities like excavation, handling, or development can also lead to their destruction.

Fossils can be destroyed through several processes: Erosion: Weathering and erosion can wear away the rock surrounding a fossil, leading to its exposure and eventual disintegration. Metamorphism: Heat and pressure from geological processes can change the mineral composition of the fossil, potentially obliterating its original structure. Chemical Weathering: Chemical reactions with water and other substances can dissolve the minerals in a fossil, causing it to deteriorate over time. Biological Activity: Organisms such as bacteria and fungi can break down organic material in fossils, leading to their degradation.
death
Petrified fossils: where organic material is replaced by minerals. Mold fossils: where the shape of an organism is preserved in sediment. Cast fossils: formed when a mold fills with minerals, creating a replica of the organism. Trace fossils: records of biological activity, like footprints or burrows. Amber fossils: organisms preserved in hardened tree resin.
