Sedimentary would be your answer. Sediment is the matter that settles to the bottom of a liquid, so as rocks, dirt and mud settled over the dead body it would fossilize inside the sedimentary rock.
During volume changes in the thoracic cavity, <u>Diaphragm</u> is primarily responsible for changes in length.
The main components of the respiratory system are the two lungs. They are located in the thoracic cavity, which is the area to the left and right of the heart. The rib cage safeguards the cavity. Other components of the respiratory system are supported by a muscular sheet known as the diaphragm.
The diaphragm contracts and pulls downward upon inspiration, or when the lungs inhale. The muscles between the ribcage tighten and pull upward at the same time. As a result, the pressure inside the thoracic cavity lowers and its size grows. Air rushes in as a result, filling the lungs.
Thus, diaphragm is responsible for the increase in length of the thoracic cavity.
