Microsaurs. Amphibians? Reptiles? Or Both?

Microsaurs (literally “little lizards”) have traditionally been nested with amphibians, like nectrideans (think of the boomerang-headers Diplocaulus and Diploceraspis). However a recent large survey nested two traditional microsaurs, Tuditanus and Utaherpeton, within the Reptilia, close to Anthracodromeus and Westlothiana.

That’s the problem I’m working on at present. I’ve added more microsaurs and finding loss of resolution. Results will follow when clarified. May miss a day or two in the meantime.
