Short summary
Selected specimens from the Jurassic ammonoid Pararnioceras sp. revealed striking changes in the conch morphology due to a syn vivo growth through a parasitic serpulid. Changes in its ontogenetic development are compared with specimens without epizoans. The ecological interpretation of the morphometric data allows the conclusion that the host possessed the ability to counteract the parasitic conch abnormalities by adapting the housing growth, thus ensuring its survival.
