Macromolecular analyses of modern dinosporin via attenuated total reflection micro-Fourier transform infrared (ATR micro-FTIR) spectroscopy revealed a variable compound: sometimes strongly influenced by the presence of brown colour-inducing (possibly eumelanin) pigments, or with additional aromatic (‘sporopollenin-like’) or aliphatic (‘algaenan-like’) moieties.

They can form resistant, organic-walled resting stages (dinocysts); the earliest body fossils appear in the Middle Triassic. Dinocyst walls are composed of a heavily cross-linked, nitrogenous, cellulose-like carbohydrate, ‘dinosporin’, which is compositionally distinct from other resistant biomacromolecules such as sporopollenin (pollen and spores) and algaenan (green algae). Macromolecular analyses of modern dinosporin via attenuated total reflection micro-Fourier transform infrared (ATR micro-FTIR) spectroscopy revealed a variable compound: sometimes strongly influenced by the presence of brown colour-inducing (possibly eumelanin) pigments, or with additional aromatic (‘sporopollenin-like’) or aliphatic (‘algaenan-like’) moieties. Here, ATR micro-FTIR spectroscopy was used to collect a large dataset from a wide range of Meso- and Cenozoic dinocysts, to investigate their molecular taphonomy. These data reveal an expected increase in the aliphaticity of dinosporin over time, likely related to early-diagenetic in situ polymerization of lipids. Furthermore, modern dinosporin variability was detected in fossil dinocysts up to the late Paleocene, highlighting the palaeoecological and taxonomical value of these chemospecific signatures. Finally, it is hypothesised that some dinosporin types might be better suited for low-salinity (aliphatic type) or high-UV (pigmented and aromatic types) aquatic environments.</dd> </dl> <div class="mbottom-default"> <h2 id="downloads">Downloads</h2> <ul class="list-unstyled"> <li class="ptop-default pbottom-default border-bottom"> <div class="pull-right"> <span class="glyphicon glyphicon-download-alt text-success"></span> <a class="btn btn-default mleft-default" href="https://biblio.ugent.be/publication/01HBGDJG14H2N740N02B9268PC/file/01HBGDTZ9AE8QZC4WDRYG2FMEV.pdf" title="Download "Meyvisch et al Dinocyst taphonomy Abstract Palass 2023.pdf"">Download</a> </div> <div>Meyvisch et al Dinocyst taphonomy Abstract Palass 2023.pdf</div> <ul class="list-unstyled list-inline text-muted"> <li> full text (Accepted manuscript) </li> <li class="divider">|</li> <li> <span class="text-success">open access</span> </li> <li class="divider">|</li> <li>PDF</li> <li class="divider">|</li> <li>74.88 KB</li> </ul> </li> </ul> </div> <div> <h2 class="mbottom-default">Citation</h2> <ul class="nav nav-tabs list-unstyled mbottom-default" role="tablist" id="citation-tab-nav"> <li role="presentation" class="active"><a href="#tab-cite-this" role="tab">Cite this</a></li> <li role="presentation"><a href="#tab-bibtex" role="tab">BibTeX</a></li> <li role="presentation"><a href="#tab-metrics" role="tab">Metrics</a></li> </ul> <script type="text/javascript" nonce="hk383ywOP5lGbbweC1uJQX"> $('#citation-tab-nav a').click(function (e) { e.preventDefault(); $(this).tab('show'); }); </script> <div class="tab-content"> <div role="tabpanel" class="tab-pane active" id="tab-cite-this"> <p class="mbottom-default"> Please use this url to cite or link to this publication: <a href="http://hdl.handle.net/1854/LU-01HBGDJG14H2N740N02B9268PC" target="_parent" itemprop="url">http://hdl.handle.net/1854/LU-01HBGDJG14H2N740N02B9268PC</a> </p> <dl class="subtle roomy"> <dt>MLA</dt> <dd> <div class="csl-entry">Meyvisch, Pjotr, et al. “Unravelling the Molecular Taphonomy of Organic-Walled Dinoflagellate Cysts via Infrared Spectroscopy.” <i>Palaeontological Association, 67th Annual Meeting, Abstracts</i>, 2023.</div> </dd> <dt>APA</dt> <dd> <div class="csl-entry">Meyvisch, P., François, H., Mertens, K.
