Adding four basal tetrapod taxa
to the large reptile tree (LRT, 924 taxa) brings new insights into temnospondyl relationships (Fig. 1). Looks like they had a separate origin with Acanthostega. Meanwhile, Ichthyostega is basal to lepospondyls, reptiles and their kin.
Certainly more taxa
will add branches to this tree topology. But for now, this is it.
