Recent work has shed light on the anatomy and development of the pectoral fin in <jats:italic>Latimeria chalumnae<\/jats:italic>. Yet, information on the development of the pelvic fin and girdle is still lacking. Here, we described the development of the pelvic fin and girdle in <jats:italic>Latimeria chalumnae<\/jats:italic> based on 3D reconstructions generated from conventional and X\u2010ray synchrotron microtomography, as well as MRI acquisitions. As in other jawed vertebrates, the development of the pelvic fin occurs later than that of the pectoral fin in <jats:italic>Latimeria<\/jats:italic>. Many elements of the endoskeleton are not yet formed at the earliest stage sampled. The four mesomeres are already formed in the fetus, but only the most proximal radial elements (preaxial radial 0\u20131) are formed and individualized at this stage. We suggest that all the preaxial radial elements in the pelvic and pectoral fin of <jats:italic>Latimeria<\/jats:italic> are formed through the fragmentation of the mesomeres. We document the progressive ossification of the pelvic girdle, and the presence of a trabecular system in the adult. This trabecular system likely reinforces the cartilaginous girdle to resist the muscle forces exerted during locomotion. Finally, the presence of a preaxial element in contact with the pelvic girdle from the earliest stage of development onward questions the mono\u2010basal condition of the pelvic fin in <jats:italic>Latimeria<\/jats:italic>. However, the particular shape of the mesomeres may explain the presence of this element in contact with the girdle.<\/jats:p>","DOI":"10.1002\/ar.24452","type":"journal-article","created":{"date-parts":[[2020,5,23]],"date-time":"2020-05-23T09:52:07Z","timestamp":1590227527000},"page":"541-558","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Development and growth of the pelvic fin in the extant coelacanth <scp><i>Latimeria chalumnae<\/i><\/scp>"],"prefix":"10.1002","volume":"304","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4727-3650","authenticated-orcid":false,"given":"Rohan","family":"Mansuit","sequence":"first","affiliation":[{"name":"D\u00e9partement Origines and Evolution UMR 7207 Centre de Recherche en Pal\u00e9ontologie, Paris, MNHN \u2010 Sorbonne Universit\u00e9 \u2010 CNRS  Paris France"},{"name":"D\u00e9partement Adaptations du Vivant UMR 7179 MECADEV, MNHN \u2010 CNRS  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ga\u00ebl","family":"Cl\u00e9ment","sequence":"additional","affiliation":[{"name":"D\u00e9partement Origines and Evolution UMR 7207 Centre de Recherche en Pal\u00e9ontologie, Paris, MNHN \u2010 Sorbonne Universit\u00e9 \u2010 CNRS  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0991-4434","authenticated-orcid":false,"given":"Anthony","family":"Herrel","sequence":"additional","affiliation":[{"name":"D\u00e9partement Adaptations du Vivant UMR 7179 MECADEV, MNHN \u2010 CNRS  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1908-5150","authenticated-orcid":false,"given":"Hugo","family":"Dutel","sequence":"additional","affiliation":[{"name":"School of Earth Sciences University of Bristol  Bristol UK"},{"name":"School of Engineering and Computer Science University of Hull  Hull UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5962-1683","authenticated-orcid":false,"given":"Paul","family":"Tafforeau","sequence":"additional","affiliation":[{"name":"European Synchrotron Radiation Facility  Grenoble Cedex France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4251-0538","authenticated-orcid":false,"given":"Mathieu D.","family":"Santin","sequence":"additional","affiliation":[{"name":"Inserm U 1127, CNRS UMR 7225, Centre for NeuroImaging Research, ICM (Brain &amp; Spine Institute), Sorbonne University  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Herbin","sequence":"additional","affiliation":[{"name":"D\u00e9partement Adaptations du Vivant UMR 7179 MECADEV, MNHN \u2010 CNRS  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,6,9]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1096-3642.1989.tb01824.x"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1096-3642.1991.tb00905.x"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature12027"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1017\/S008045680001471X"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/jez.1402670309"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature04119"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/2041-9139-4-3"},{"key":"e_1_2_10_9_1","first-page":"1","volume-title":"Gaining ground: The origin an evolution of Tetrapods","author":"Clack J.
