In this study, we tested the use of continuous cranial shape variation in distinguishing the two living species of\n                    <jats:italic>Mecistops<\/jats:italic>\n                    : the West African slender\u2010snouted crocodile (\n                    <jats:italic>M. cataphractus<\/jats:italic>\n                    ) and the Central African slender\u2010snouted crocodile (\n                    <jats:italic>M. leptorhynchus<\/jats:italic>\n                    ). Using a combination of geometric morphometric characters and ratios of linear measurements, we identified statistically significant variation in cranial bone and overall skull shape of mature individuals that corroborates existing molecular and discrete morphological evidence for two distinct, extant species within\n                    <jats:italic>Mecistops<\/jats:italic>\n                    . Specifically, variation in the shape of the nasal appears particularly diagnostic, while ratios involving metrics of snout length to snout width at the premaxillary notch offer distinguishing features easily measured in the field. Because of the complementary results and applications of the morphometric and cranial ratio analyses, we argue that both methodologies remain relevant to species identification. Moreover, we recommend continued cooperation between geneticists and morphologists in diagnosing species of conservation concern.\n                  <\/jats:p>","DOI":"10.1002\/jmor.21365","type":"journal-article","created":{"date-parts":[[2021,5,4]],"date-time":"2021-05-04T09:25:46Z","timestamp":1620120346000},"page":"1219-1232","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Use of continuous cranial shape variation in the identification of divergent crocodile species of the genus\n                    <i>Mecistops<\/i>"],"prefix":"10.1002","volume":"282","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1808-9472","authenticated-orcid":false,"given":"Amanda N.","family":"Carr","sequence":"first","affiliation":[{"name":"Department of Wildlife Ecology &amp; Conservation University of Florida  Gainesville Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4552-1734","authenticated-orcid":false,"given":"Jennifer H.","family":"Nestler","sequence":"additional","affiliation":[{"name":"Cherokee Federal  Homestead Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kent A.","family":"Vliet","sequence":"additional","affiliation":[{"name":"Department of Biology University of Florida  Gainesville Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4044-8371","authenticated-orcid":false,"given":"Christopher A.","family":"Brochu","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences University of Iowa  Iowa City Iowa USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4500-9052","authenticated-orcid":false,"given":"Christopher M.","family":"Murray","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences Southeastern Louisiana University  Hammond Louisiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3095-7546","authenticated-orcid":false,"given":"Matthew H.","family":"Shirley","sequence":"additional","affiliation":[{"name":"Institute of Environment Florida International University  North Miami Florida USA"},{"name":"Project Mecistops  Sarasota Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,5,11]]},"reference":[{"key":"e_1_2_10_2_1","unstructured":"AdamsDC CollyerML KaliontzopoulouA.2018.Geomorph: Software for geometric morphometric analyses.
