I am now working with the following hypothesis of fingers and phalanges:
x-2-3-4-x Basal Paraves
x-2-3-4-x Basal eumaniraptora
x-1-2-1-x Modern bird
Numbers represent the number of phalanges. For example, this shows 3 phalanges in the third finger (III) of basal paraves.
For comparison, the dinosaur pattern is 2-3-4-x-x.
