The most well known types of fossilization are permineralization and carbonization or distillation. Certain parameters must be met in order for fossils to form. They are a rapid death and fast burial in relatively anaerobic conditions. Any prolonged exposure to the elements will decrease the chances of fossilization.
The symptoms of chronic pancreatitis are similar to those of acute pancreatitis. Patients frequently experience constant pain in the upper abdomen that radiates to the back. In some patients, the pain may be disabling. Other symptoms may include weight loss caused by poor absorption (malabsorption) of food.
