3D morphology further extends beyond the conventional descriptions

Penelitian - The scientists present high-resolution X-ray microtomography (microCT) that allows to improve the standard morphological description of Eupolybothrus liburnicus. 3D images of holotype and paratype specimens are the universal and virtual representations of the type of material in first-generation centipede cybertype published.

Morphology remains important for understanding organismal diversity and relationships even in the growing genomic era in systematics. The taxa method on fossil studies will calibrate phylogenetic trees, understand evolutionary history and compare structures to understand functions, organism ontogeny, development and even analyze all integrative aspects.

The use of microCT is one method to catalyze morphology-based research in biology where sophisticated software enables the study of soft tissues, muscles and other internal structures. This method has been increasingly popular in modern Arthropod systematics and has been applied to amber fossil studies.

Microtomographic data reveal the character further and it is possible to hypothesize the function of some male secondary structures and marital behavior in species. Nesrine Akkari of the Natural History Museum Vienna in Vienna and colleagues also compared parts of the female reproductive system of E. liburnicus with species of the same genus, including E. cavernicolus.

"We promote the creation and use of 'avatar-avatar myriapod' and present the volumetric image data of the male and female paratype holotype. MicroCT data is the only source of information available with the potential to complement conventional morphological and molecular characterization," said Akkari and colleagues.
