title: [Paleopathology of Ichthyopterygia].
abstract: During microscopic histological studies of ichthyosaur bones the authors found that the bones of young ichthyosauri are well preserved without signs of inflammation. In the bones of old animals reproductive reactions were present. Thus, the severity of pathological alterations most likely depends on the age of the animals.
