indominus rex Posted February 5, 2019 Share Posted February 5, 2019 Hello, I wanted to know the ID of this tooth which I was told was Postosuchus. It is from New Mexico Bull canyon and is quite a good sized tooth. Is nicely serrated as well. Regards, indominus rex Life started in the ocean. And so did my interest in fossils.

TyBoy Posted February 5, 2019 Share Posted February 5, 2019 (edited) I dont know all I can say reading Troodons topic is that Postosuchus is only described from New Mexico's Rock Point formation and not Bull Canyon, shown on tables "Heckerts 2015". Does not mean it does not exist just not described. In an earlier paper Hunt 2001 refers to an ilium beloning to Postosuchus from the Bull Canyon, so ? Found this paper that describes those teeth and indicates that the serration density is 3/mm on both carinae https://escholarship.org/uc/item/7848q4c8 Edit Please note this comment in that paragraph: "This tooth is indistinguishable from the posterior premaxillary and anterior maxillary teeth of phytosaurs, which makes identification of an isolated tooth of this morphology untenable."
