These data demonstrate anatomical commonalities between the lungs of <jats:italic>P. palpebrosus<\/jats:italic> and <jats:italic>A. mississippiensis<\/jats:italic>, and a few notable differences. The structural similarities are (a) a proximally narrow, distally widened, hook\u2010shaped primary bronchus; (b) a cervical ventral bronchus that branches of the primary bronchus and immediately makes a hairpin turn toward the apex of the lung; (c) a sequential series of dorsobronchi arising from the primary bronchus caudal to the cervical ventral bronchus; (d) intraspecifically highly variable medial sequence of secondary airways; (e) sac\u2010like laterobronchi; and (f) grossly dead\u2010ended caudal group bronchi in the caudal and ventral aspects of the lung. The primary differences between the two taxa are in the overall number of large bronchi (fewer in <jats:italic>P. palpebrosus<\/jats:italic>), and the number of branches that contribute to the cardiac regions. Imaging data of both a live and deceased specimen under varying states (postprandial, fasting, total lung capacity, open to atmosphere) indicate that the caudal margin and position of the lungs shift craniocaudally relative to the vertebral column. These imaging data suggest that the smooth thoracic ceiling may be correlated to visceral movement during ventilation, but this hypothesis warrants validation. These results provide the scaffolding for future comparisons between crocodilians, for generating preliminary reconstructions of the ancestral crocodilian bronchial tree, and establishing new hypotheses of bronchial homology across Archosauria.<\/jats:p>","DOI":"10.1002\/ar.24919","type":"journal-article","created":{"date-parts":[[2022,4,4]],"date-time":"2022-04-04T09:06:16Z","timestamp":1649063176000},"page":"3037-3054","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Architecture of the bronchial tree in Cuvier's dwarf caiman (<i>Paleosuchus palpebrosus<\/i>)"],"prefix":"10.1002","volume":"305","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8636-925X","authenticated-orcid":false,"given":"Emma R.","family":"Schachner","sequence":"first","affiliation":[{"name":"Department of Cell Biology and Anatomy, School of Medicine Louisiana State University Health Sciences Center  New Orleans Louisiana USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9107-124X","authenticated-orcid":false,"given":"Raul E.","family":"Diaz","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences California State University Los Angeles  Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rob","family":"Coke","sequence":"additional","affiliation":[{"name":"San Antonio Zoo  San Antonio Texas USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott","family":"Echols","sequence":"additional","affiliation":[{"name":"The Medical Center for Birds  Oakley California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0811-9279","authenticated-orcid":false,"given":"Michelle L.","family":"Osborn","sequence":"additional","affiliation":[{"name":"Department of Comparative Biomedical Sciences, School of Veterinary Medicine Louisiana State University  Baton Rouge Louisiana USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4446-3405","authenticated-orcid":false,"given":"Brandon P.","family":"Hedrick","sequence":"additional","affiliation":[{"name":"Department of Cell Biology and Anatomy, School of Medicine Louisiana State University Health Sciences Center  New Orleans Louisiana USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,4,4]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7580.2009.01202.x"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.7717\/peerj.6580"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.2019.0140"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1098\/rsos.180983"},{"key":"e_1_2_7_6_1","first-page":"224","article-title":"Die embryonalentwicklung der lungen bei krokodilen und seesschildkr\u00f6ten","volume":"84","author":"Broman I.","year":"1939","journal-title":"Jahrbuch f\u00fcr Morphologie Mikroskopisch\u2010Anatomische"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1163\/156853810791769392"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/00222933.2012.724723"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/cne.900270304"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7998.1975.tb01405.x"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.resp.2006.04.014"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1152\/physiol.00056.2014"},{"issue":"6","key":"e_1_2_7_13_1","first-page":"962","article-title":"Similarity of crocodilian and avian lungs indicates unidirectional flow is ancestral for archosaurs","volume":"55","author":"Farmer C.
