T-tests comparing Notharctus distal phalanx morphology to extant primate ungular and grooming phalanges.

The results of t-tests comparing Notharctus tenebrosus specimens to ungulae and grooming claw group means. For each variable, the first row (‘U’) is comprised of t-values from comparisons to ungular phalanges; the second (‘G’) from comparisons to grooming phalanges. The smallest absolute t-value indicates which extant group the fossil is most similar to. Asterisks mark significant comparisons at the Bonferroni corrected alpha of 0.0042.aAll specimen numbers are from AMNH.*Significant comparisons (p
