Jacisin and Hopkins—Fossil newts from the Oligocene of Oregon
729
Figure 11. Strict consensus tree of 16 most parsimonious trees (length = 662 steps) from our molecularly constrained analysis without the “vertebrae-only” fossil taxa. Extinct taxa are in bold.
In all four of our strict consensus trees (Figs. 8–11), we
recover a group including all extant and fossil species of Taricha, the vertebrae-only Taricha miocenica, as well as,
curiously, Notophthalmus robustus, when they are included. Our strict consensus trees also did not place any fossil or extant North American newts within the Eurasian Molgini.
