Повний текст джерелаColeoids (cuttlefish, squid, and octopuses) represent 99% of the 800 species of modern cephalopods and play key roles in modern marine ecosystems. Their bodies are predominantly composed of soft tissues that rarely preserve in the fossil record. As such, the great majority of fossil coleoid remains are in fact rigid elements, such as the gladius (comparable to a squid pen), rather than the soft anatomical characters that form the basis of modern coleoid systematics. This means that the ecology of fossil taxa, and the relationships between fossil and modern clades remain unclear. In turn, determining proper dating of the origination of modern clades, and their shifts to paleo- and modern ecological niches, remains a major challenge for reconstructing their evolutionary history. In exceptional preservation deposits (Lagerstätten), coleoid soft parts do fossilize. The increasing capabilities of high-resolution, non-destructive imaging techniques (µCT, XRF, RTI), opens up new avenues for improving the resolution of anatomical data from these fossilized specimens, advancing our understanding around these questions. The aim of this thesis is to use these techniques to improve our knowledge of the systematics and ecology of coleoids at key periods in their evolutionary history. It focuses on coleoids from two sites with very different environments and preservation conditions: The Callovian-aged La Voulte-sur-Rhône (France), which represents a bathyal ecosystem where body fossils were preserved in 3D with pyrite and apatite, and the Upper Cretaceous (Cenomanian and Santonian) outcrops in Lebanon where coleoids were compressed within thin shallow marine limestone layers and their soft tissues were fossilized as 2D imprints. CT and Synchrotron X-ray microtomography analyses performed on multiple specimens of Vampyronassa rhodanica from La Voulte-sur-Rhône, allowed a re-examination of its external and internal morphology. Comparisons with other fossils and the extant relative Vampyroteuthis infernalis demonstrate that some key Vampyroteuthidae characters, such as its unique type of sucker attachment, were already present in the Jurassic. In addition, many characters in V. rhodanica indicate a pelagic predatory lifestyle, which is totally distinct from the deep-sea habitat of Vampyroteuthis. Investigation of the specimens assigned to V. rhodanica also led to the recognition of a new taxon, Vampyrofugiens atramentum. The presence of an ink sac and internal luminous organs in this new taxon is a pattern which is unknown in other fossil taxa, and raises questions about this organism's way of life. Dorateuthis syriaca, a key coleoid species from the Lebanese deposits, was re-appraised using a combination of high-resolution imaging techniques and comprehensive morphological measurements. This study was conducted on 54 individuals (including the holotype), making it the largest of its kind for D. syriaca. It allowed for a reappraisal of the species and holotype anatomy, and provided new systematic and ecological information. Morphological variations observed in the gladius were not determined to be site-dependent, rather suggest a greater intraspecific variability than previously assumed. This result raises questions about the definition of these characters in phylogenetic analyses. The overall results show that coleoids achieved a high level of ecological diversity as early as the Jurassic, and played an important role in marine ecosystems during the Mesozoic. The level of anatomical detail observed (muscular organization of the arms, elements of the nervous system) opens up new perspectives for comparisons between modern and fossil , and paves the way for better integration of this high resolution data into phylogenetic and paleoecological reconstructions

Повний текст джерелаThe fossil record is incomplete and does not really account for ancient biodiversity. Some exceptionally well-preserved deposits are rich in "soft" organisms that are rarely fossilized. X-ray tomography has revealed remarkable biological structures (eggs, internal organs) allowing us, for example, to reconstruct reproductive traits in Polychelida (Decapoda) from the Jurassic site of La Voulte-sur-Rhône. As the causes of such preservation are still poorly known, in situ analyses of the mineralogical composition of fossil arthropods have enabled us to reconstruct the fossilization processes at the same site and at a Cretaceous site in Lebanon. We thus show that biodegradation is essential in fossilization, and that the mode of preservation is explained by the precipitation around the fossil of a concretion (volume fossils) or not (flat fossils). We discuss the effect of microenvironments and associated microorganisms
