New amniote phylogeny, focused on placement of mesosaurs

Interesting paper. Finds mesosaurs at the base of Sauropsida. Also finds that turtles are related to parareptiles (such as pareiasaurs), but that parareptiles are themselves close to diapsids, which would make the turtles-as-anapsids/turtles-as-diapsids dichotomy less...of a dichotomy.

As always, worth bearing in mind that a phylogenetic tree is always a hypothesis subject to refutation by new data.

Another interesting study!  Sort of expected I guess, but I'm still surprised to see turtles regrouped with parareptiles.
