A skunk and two otters enter the LRT

Three taxa
enter the large reptile tree (LRT, 1875+ taxa) today. Mephitis, the skunk (Fig. 1), Enhydra, the sea otter, and Lontra, the river otter, are all extant members of the clade Carnivora.

All three are traditional musteloids (= weasels).
In the LRT (subset Fig. 2) the otters do nest with Mustela, the weasel, but Mephitis, the skunk, nests between Procyon, the raccoon, and the mongoose (Herpestes).

Convergence
In dorsal view (Fig. 1) the squamosal of the skunk skull has a lateral process. Where else in Tetrapoda do we find such a squamosal process or shape? 1) Coelurosauravus and 2) Triceratops.
