Arthropods represent one of the most diverse groups of organisms, displaying an extraordinary range of morphologies and lifestyles while inhabiting nearly every environment on Earth. Their fossil record extends back to the Early Cambrian, providing a deep temporal framework to investigate evolutionary patterns, morphological innovations, and ecological diversification within the group.


Parasitic organisms are everywhere. They are a major component of modern ecosystems. Parasitic organisms are playing key roles within food webs and ecosystem. In addition, a parasitic lifestyle evolved in many different lineages, exhibits a wide range of morphologies, parastic strategies, or hosts. Thus, parasitic organisms are an interesting topic to investigate.


Excpetionnal mode of preservation can yield incredible insights on ancient organisms. Among them, the phosphatisation is drawing attention. Phosphatisation can finely replciated morphological and anatomical details. Phospahtisaiton can allwo the preservation in three dimension of minute organisms, as well as parasites


Scientific illustrations are important tools for studying and communicating biological and palaeontological data.  By offering another point of view and highlighting specific details, illustrations help to better understand shapes, structures, and fine features. This makes them a valuable complement to photographs and other types of data, for both specialists and a broader audience.
