Summary
[edit]
| Description |
English: Phylogeny, biogeography and digit reduction in Oviraptorosauria. Map of China and Mongolia (top left) showing the distribution of oviraptorids in the Late Cretaceous of Asia. Time-calibrated majority-rule consensus of 9 most parsimonious trees for Oviraptorosauria. Branches are coloured according to maximum-likelihood reconstruction of the ratio of manual ungual III-4 to I-2 (warmer colours indicate a lower ratio), as a proxy for digit reduction. Hand reconstructions show representative morphotypes and increase in robustness of the first digit. Pie charts on nodes represent posterior probability of ancestral state based on stochastic mapping of biogeographic distributions (purple: Asia; orange: North America; black: southern China; white: Gobi Desert). Geographical ranges for each taxon are displayed at the tip of the branch. Taxa with greyed-out names are those for which digit proportion data does not exist, leaving the condition for the entire branch including the tip to be inferred by ancestral state estimation. |
