PHRAGMOCONE Meaning and
Definition
-
The term "phragmocone" refers to the chambered portion of the shell found in some marine organisms, particularly cephalopods such as ammonites and nautiloids. It is a vital anatomical structure that is typically coiled or spirally arranged, forming a logarithmic spiral. Composed primarily of calcium carbonate, the phragmocone is responsible for providing structure and protection for the soft-bodied cephalopod organism.
Within the phragmocone, a series of internal septa or walls separate each chamber. The organism continually adds new chambers to the open end of the phragmocone as it grows, while the older chambers are sealed and remain behind. These sealed chambers are known as the siphuncle. The siphuncle serves multiple purposes, including providing buoyancy control and facilitating the expulsion or intake of water and gases.
The study of phragmocones can provide valuable insights into the life history, ecology, and evolutionary relationships of cephalopods. By examining the arrangement, size, and shape of the chambers, researchers can determine the growth pattern of extinct and living species of cephalopods. In addition, the intricate structures found within the phragmocone can provide information about the paleoecology, environmental conditions, and even the mode of life of these ancient organisms.
In summary, the phragmocone is the chambered portion of the shell in cephalopods, playing a crucial role in providing structural support, facilitating growth, and assisting in various physiological processes.

Etymology of PHRAGMOCONE
The word "phragmocone" is derived from two Greek words: "phragmos" which means "fence" or "enclosure", and "konos" which means "cone". In the context of the word, "phragmocone" refers to a specific part of the internal shell of cephalopods, such as ammonites and nautiloids, which is a chambered cone-like structure. The term was coined in the 19th century and is commonly used in paleontology and zoology.
