The most commonly fractured teeth were the mandibular (n = 33, 37.5%) and maxillary incisor teeth (n = 22, 25.%), followed by the maxillary canine and maxillary molar teeth (each n = 11, 12.5%), and maxillary premolar, mandibular canine, mandibular premolar, and mandibular molar teeth (each n = 6, 6.8%). Fossil evidence suggests that the modern thylacine Thylacinus cynocephalus, whose name means "dog-headed pouched one" emerged about 4 million years ago. The incisor and canine teeth each have a single root (Figures 2A,B,D,E). The tooth roots were evaluated for total number, concrescence, convergence, fusion, convergence, divergence, and/or dilaceration. Aust J Zool.

The other threat is cars (and their drivers) killing them on the roads. To classify the age of the specimen at the time of collection, the width of the root canal was standardized as a percentage of the width of the whole root of the maxillary canine teeth halfway between the cementoenamel junction and apex of the tooth. WebAppearance. (2011) 285:292300. They would hunt alone or with a partner. Other noted dental malocclusions included buccal rotation of right maxillary first (n = 1) and second (2) incisor teeth; mesioversion of a right maxillary first incisor tooth (n = 1), left maxillary first (n = 1) and second (1) incisor teeth; buccoversion of a right maxillary first incisor tooth (n = 1) and right mandibular first incisor tooth (n = 1); and linguoversion of two mandibular second incisor teeth, one of which also had a morphologically abnormal crown. doi: 10.1890/0012-9658.
