Area of Science:

Palaeopathology
Vertebrate Biology
Imaging Technology

Background:

Traditional palaeopathological studies rely on external morphology, limiting diagnostic accuracy due to destructive methods.
Understanding bone physiology and healing in extinct organisms requires advanced analytical techniques.
Existing methods struggle to provide in-depth, non-destructive analysis of internal pathologies.

Purpose of the Study:

To present external and internal descriptions of pathologies in extant and extinct archosaurs using X-ray MicroTomography (micro-CT).
To demonstrate the crucial role of combined external/internal diagnosis for differentiating pathological conditions.
To highlight the importance of comparative species analysis in palaeopathological interpretation.

Main Methods:

Utilized X-ray MicroTomography (micro-CT, XMT) for non-destructive, high-resolution 3D analysis of internal bone structures.
Performed external and internal descriptions of pathologies in both extant and extinct archosaurs.
Employed comparative analysis of extant species, both directly and from literature, for diagnosis.

Main Results:

Micro-CT imaging provides detailed internal and external descriptions of pathologies, crucial for accurate diagnosis.
The combination of internal and external data significantly improves differentiation between pathological conditions.
Comparative analysis with extant species aids in diagnosing typical pathologies across vertebrate groups.

Conclusions:

X-ray microtomography (micro-CT) is essential for detailed and reliable interpretation of palaeopathologies.
Integrating micro-CT with comparative studies of extant species enhances diagnostic capabilities for vertebrate pathologies.
Micro-CT is an accessible and vital tool for future palaeopathological research.
