| Zusammenfassung |
| For more than a decade, Magnetic Resonance Imaging (MRI) has been routinely
employed in clinical diagnostics because it allows non-invasive studies of
anatomical structures and physiological processes in vivo and to differentiate
between healthy and pathological states, particularly of soft tissue. Here,
we demonstrate that MRI can likewise be applied to fossilized biological
samples and help in elucidating paleopathological and paleoecological
questions: Five anomalous guards of Jurassic and Cretaceous belemnites are
presented along with putative paleopathological diagnoses directly derived
from 3D MR images with microscopic resolution. Syn vivo deformities of both the
mineralized internal rostrum and the surrounding former soft tissue can be
traced back in part to traumatic events of predator-prey-interactions, and
partly to parasitism. Besides, evidence is presented that the frequently
observed anomalous apical collar might be indicative of an inflammatory
disease. These findings highlight the potential of Magnetic Resonance
techniques for further paleontological applications. |
