Posterior probabilities for fossil claws ecological grouping.

Predictions were generated for fossil taxa by two predictive models: Model 1 based on ungual bone curvatures, and for claws in possession of the keratinous sheath, Model 2 based on ungual bone and sheath curvatures. GRND = Ground-dwelling, PRCH = Perching, CLMB = Climbing, PRED = Predatory. Highlighted cells indicate classification for the claw. Yellow = classification by Model 1 alone (no sheath data), green = classification for which Models 1 and 2 are in agreement, red = classification for which Models 1 and 2 are in disagreement.
