    Brachauchenius lucasi finds are more based in Kansas, but examples in Eagle Ford Texas have been found, most notably Willison's 1907 second B. lucasi skull which has been found in the same area.

    There is a possibility that this tooth could actually be Polyptychodon hudsoni which have been also found in Eagle Ford, but based on the morphology of the tooth (especially the root part near the crown), I think it is more likely B. lucasi.

    User Feedback

    Very nice tooth. Wondering if there is someone close to you who could possibly give a positive ID? That way if someone does have a similar tooth and is using our collections area to help get an ID, it could be more positive. Either a great entry for the collections section.
