Quick note: progress behind the scenes

Apologies
for not getting to the latest comments. I have not opened a week’s worth of snail-mail and bills, so you’re not alone.

Some changes to the LRT
happened while reexamining the data on which the matrix scores are input.

  1. Tulerpeton now nests between Ichthyostega and Eucritta.
  2. Bystrowiella now nests with Solenodonsaurus.

That’s really not a lot of news
for the amount of work that went into getting those. All the related taxa had little changes to toes, teeth, etc. …all toward a greater understanding of what’s going on here. It all started with attempting a lateral view of the skull of Bystrowiella (Fig. 1; (Witzmann and Schoch 2017; Middle Triassic), and see where it led…

Figure 1. Bystrowiella skull in lateral view. Note the large tooth roots on the premaxilla. we don't know how long those buck teeth would have been.
