six.2.step 1 Diagnosis the new Genus Revueltosaurus
The latest holotypes out-of Roentgen. callenderi (NMMNH P-4957), “Revueltosaurus” hunti (NMMNH P-29357), while the recently blamed species “Revueltosaurus” (= Pekinosaurus) olseni (YPM 7666; Heckert ainsi que al., 2012 ) for every happened to be an individual separated tooth which had been the foundation to possess their specific medical diagnosis. Lately, Heckert ainsi que al. ( 2012 ) detected the newest genus Revueltosaurus (comprising Roentgen. callenderi, Roentgen. hunti, and R. olseni) utilizing the pursuing the mixture of character states: size (tooth crowns as much as seven to fifteen-mm significant); multiple quick denticles (more than eight per carina) which might be counterbalance (sub-perpendicular) with the tooth margin; denticles proportionately brief and sometimes used for the tooth by the real occlusion; shortage of a real cingulum; premaxillary enamel crowns which can be as much as doubly high since maxillary/dentary enamel crowns and you can weakly recurved; and you can maxillary/dentary tooth crowns phyllodont (leaf-shaped). grams., Ezcurra, 2016 ). Particularly, the combination of one’s sized one’s teeth, what number of the brand new denticles, and also the direction of your denticles convergence with other distantly related taxa (e.g., Silesaurus opolensis, Dzik, 2003 ; Azendohsaurus madagaskarensis, Flynn et al., 2010 ). The type “denticles proportionately brief and frequently used on the enamel by specific occlusion” lacks accuracy regarding what exactly is felt “short,” and wear pattern is tough in order to rule out in other taxa and utilizes a certain ages of enamel inside the replacement for period (i.age., young teeth would not be diagnosable since there wouldn’t be worn).
