Biochron is a term that is commonly used in the field of geology and paleontology. It refers to a specific period of time in which a particular group of organisms existed and evolved. This term is important in understanding the evolution of life on Earth and helps scientists to study the different stages of life that have existed throughout history.
Definitions
Biochron is defined as a division of geological time that is characterized by the presence of a particular group of organisms. It is also known as a biostratigraphic unit, which is a subdivision of geological time based on the presence of certain fossil species.
Origin
The term biochron was first used by the American paleontologist George Gaylord Simpson in the 1940s. He used the term to describe the different stages of evolution that had occurred throughout history. Since then, the term has been widely used in the field of geology and paleontology.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, biochron is defined as “a unit of geological time characterized by a particular assemblage of fossils.”
The Oxford English Dictionary defines biochron as “a division of geological time based on the presence of a particular group of organisms.”
Associations
Biochron is closely associated with the study of biostratigraphy, which is the branch of geology that deals with the identification and correlation of rock strata based on the fossils they contain. It is also associated with the study of paleontology, which is the study of the history of life on Earth based on fossils.
