Axiomatic Panbiogeography

offers an application of incidence geometry to historical biogeography by defining collection localities as points, tracks as lines and generalized tracks as planes.

Kinosternidae

Following up on the two part track one node  analysis of Dermatemys the following outline synthesis for the Mud turtles seems possible. Other species would have to be explained but it seems that at the genus and subfamily level that this is actually real.



This very simple, easy and quickly constructed scenario contrasts starkly with that recently published by Iverson et. al.

Interestingly,  the really new feature they found support for molecularly and named Cryptochely was responsible for my looking into these species distributions ( localized Dermateys like tracks) in the first place.  Futher the Dernaytemys two part track can explain the relation of acuta and creaseri to herrerai etc. ... but beyond this the difference is huge.  There needs to be a way to decide if one must invoke three separate dispersals south and a couple north or if rather a simple vicariance from a widespread ancestral kniosternide with dermatemyid populations had occurred along the range indicated below.
