Suppression of functional tooth replacement is characteristic of marsupials, where most placentals have the primitive diphyodont pattern of two generations of incisor, canine and premolar teeth. Canine and molar tooth dimensions of four species of marsupial carnivores (thylacine\n                    <jats:italic>Thylacinus cynocephalus<\/jats:italic>\n                    , Tasmanian devil\n                    <jats:italic>Sarcophilus harrisii<\/jats:italic>\n                    and two quolls\n                    <jats:italic>Dasyurus<\/jats:italic>\n                    spp\n                    <jats:italic>.<\/jats:italic>\n                    ) and canine dimensions of seven eco-morphologically equivalent placental carnivore species were measured from museum specimens. Canine dimensions were measured in a time series on live wild-living individual devils and quolls. The canine teeth and to a lesser extent the molar teeth of marsupial carnivores continue to erupt through life, resulting in a net increase in tooth height and diameter, a phenomenon not evident in placental carnivores. Potential mechanisms causing over-eruption include tooth wear and gradual release of occlusal pressure as the individual grows. Over-eruption in marsupial carnivores may be a compensatory response for tooth size limits imposed by monophyodont tooth replacement, ensuring that animal's teeth are scaled to jaw size from juvenile to adulthood.\n                  <\/jats:p>","DOI":"10.1098\/rspb.2023.0644","type":"journal-article","created":{"date-parts":[[2023,12,13]],"date-time":"2023-12-13T03:05:26Z","timestamp":1702436726000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Over-eruption in marsupial carnivore teeth: compensation for a constraint"],"prefix":"10.1098","volume":"290","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7558-9022","authenticated-orcid":true,"given":"Menna E.","family":"Jones","sequence":"first","affiliation":[{"name":"School of Natural Sciences, University of Tasmania, Hobart, Tasmania 7001, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2023,12,13]]},"reference":[{"key":"e_1_3_8_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-349-02721-7_16"},{"key":"e_1_3_8_3_2","doi-asserted-by":"crossref","first-page":"281","DOI":"10.1071\/9780643069862","volume-title":"Predators with pouches: the biology of carnivorous marsupials","author":"Jones ME","year":"2003","unstructured":"Jones ME. 2003 Convergence in ecomorphology and guild structure among marsupial and placental carnivores.
