The results obtained through histological examination show that <jats:italic>Seymouria<\/jats:italic> has pleurodont implantation with ankylosis of the tooth to the labial side of the jawbone. The dentary and maxillary teeth exhibit similar dental characteristics, such as the attachment bone (alveolar bone) and cementum rising above the jawbone on the base of the tooth, and smooth carinae extending lingually toward the tooth apex. Additionally, the clear presence of plicidentine, infolding of dentine into the pulp cavity, was found within the tooth root extending into the tooth crown. Lastly, the tooth replacement pattern is alternating, illustrating that <jats:italic>Seymouria<\/jats:italic> retains the classic primitive condition for tetrapods, a pattern that is continued in amniotes. Our results provide an important basis for comparison with other stem amniotes and with amniotes.<\/jats:p>","DOI":"10.1111\/joa.13715","type":"journal-article","created":{"date-parts":[[2022,6,28]],"date-time":"2022-06-28T06:09:56Z","timestamp":1656396596000},"page":"628-634","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Dental anatomy and replacement patterns in the early Permian stem amniote, <i>Seymouria<\/i>"],"prefix":"10.1111","volume":"241","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5753-5231","authenticated-orcid":false,"given":"Tea","family":"Maho","sequence":"first","affiliation":[{"name":"Department of Biology University of Toronto Mississauga  Mississauga ON Canada"},{"name":"International Center of Future Science Jilin University  Jilin Province China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert R.","family":"Reisz","sequence":"additional","affiliation":[{"name":"Department of Biology University of Toronto Mississauga  Mississauga ON Canada"},{"name":"International Center of Future Science Jilin University  Jilin Province China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,6,27]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/02724634.2019.1694535"},{"key":"e_1_2_9_3_1","first-page":"e8698","article-title":"Postcranial anatomy and histology of Seymouria, and the terrestriality of seymouriamorphs","volume":"8","author":"Bazzana K.D.","year":"2020","journal-title":"PeerJ (San Francisco, CA)"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1671\/0272-4634(2000)020[0253:ROSSSF]2.0.CO;2"},{"key":"e_1_2_9_5_1","doi-asserted-by":"crossref","first-page":"63","DOI":"10.5962\/p.226648","article-title":"First occurrence of Seymouria (Amphibia: Batrachosauria) in the lower Permian Rotliegend of Central Germany","volume":"62","author":"Berman D.S.","year":"1993","journal-title":"Annals of Carnegie Museum"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1139\/e87-169"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2018.01630"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00114-014-1228-5"},{"key":"e_1_2_9_9_1","first-page":"1","article-title":"Permische Stegocephalen und Reptilien aus Texas","volume":"51","author":"Broili F.","year":"1904","journal-title":"Palaeontographica"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1671\/0272-4634(2006)26[138:TSHITC]2.0.CO;2"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1671\/0272-4634(2003)23[67:ANBTFT]2.0.CO;2"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-185X.2006.00003.x"},{"key":"e_1_2_9_13_1","first-page":"1","article-title":"Tooth replacement phenomena in the lower vertebrates","volume":"52","author":"Edmund A.G.","year":"1960","journal-title":"Life Science Division Contributions Royal Ontario Museum"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1080\/02724634.2015.982797"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1643\/0045-8511(2006)2006[337:AIITOO]2.0.CO;2"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02985990"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.2992\/0097-4463(2005)74[217:NSAROT]2.0.CO;2"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.2992\/0097-4463(2007)76[53:FDOSOL]2.0.CO;2"},{"key":"e_1_2_9_19_1","first-page":"1","article-title":"A redescription of the cranial anatomy of Seymouria baylorensis, the best known seymouriamorph (vertebrata;
