Morphometric analysis attempts to explain such variation in form in evolutionary and functional contexts. Developmental morphometric analyses of vertebrate crania are less common, and many taxa are underrepresented. For example, the published morphometric studies of crocodilian cranial development focus mainly on posthatchling head development, with few, incomplete morphometric analyses of prehatchling heads. To further explore ontogenetic changes in the alligator head, we recorded and analyzed six linear cranial measurements in 77 preserved embryonic and hatchling American alligators (\n                    <jats:italic>Alligator mississippiensis<\/jats:italic>\n                    ) representing 20 different stages. Examination of individual measurements revealed nonlinear changes in growth rate during development, suggesting a level of dynamic complexity worthy of further analysis. Using principal components analysis,\u00a0we identified three distinct phases in prenatal alligator head growth. The second (intermediate) phase disrupts an otherwise monotonic developmental trajectory and represents a phase of reduced snout growth. Although this is a detailed description of prehatchling ontogenetic trajectory of the alligator head, further studies in other crocodilians are needed to assess evolutionary patterns among crocodilians.\n                  <\/jats:p>","DOI":"10.1002\/jmor.21472","type":"journal-article","created":{"date-parts":[[2022,4,4]],"date-time":"2022-04-04T02:19:24Z","timestamp":1649038764000},"page":"805-814","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Ontogeny of the American alligator (\n                    <i>Alligator mississippiensis<\/i>\n                    ) prenatal head: A morphometric approach"],"prefix":"10.1002","volume":"283","author":[{"given":"Simon C.","family":"Beeching","sequence":"first","affiliation":[{"name":"Department of Biology Slippery Rock University Slippery Rock Pennsylvania USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruth M.","family":"Elsey","sequence":"additional","affiliation":[{"name":"Louisiana Department of Wildlife and Fisheries Baton Rouge Louisiana USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2550-905X","authenticated-orcid":false,"given":"Susan J.","family":"Rehorek","sequence":"additional","affiliation":[{"name":"Department of Biology Slippery Rock University Slippery Rock Pennsylvania USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,4,14]]},"reference":[{"issue":"1","key":"e_1_2_10_2_1","first-page":"181","article-title":"Mathematical models for growth in alligator (Alligator mississippiensis) embryos developing at different incubation temperatures","volume":"187","author":"Bardsley W.
