Spitting in the face of parsimony I see.
Even if the vascular groove pattern is interpreted as being convergent with
lorrines, surely the other psittaciform characters of the mandible means
it's more likely a pseudo-loriine parrot than some other group with less
similar dentaries.  Or are basal psittaciform dentaries so unlike derived
ones that they couldn't be told from non-psittaciform dentaries?
