Tumarkin, Chinsamy and Dodson, 2001. Trauma in birds: Is it reflected
as interruptions in osteogenesis? JVP 21(3) 109A.
Neornithines don't have lines of arrested growth
(LAGs) in their bone cross sections, indicating they grow
continuously.
Dinornis and Gastornis
sometimes have a few, according to the biggest of the 3 Nature papers on
dinosaur growth (can't find the ref at the moment).
[...] The confusion is with Patagopteryx, which
has one LAG in the cross section that's been taken. This is odd and has
been suggested to be due to a pathology, such as trauma or nutritional
deprivation. To solve the problem, the most time-consuming and complex
method was chosen. Take a cross section of another Patagopteryx
individual you say?
How many specimens do we have?
Wharton, 2001. The evolution of the avian brain.
JVP 21(3) 113A.
[...] Bambiraptor, Archaeopteryx and pygostylians
have reduced optic lobes, unlike Troodon, Tyrannosaurus and Allosaurus.
This supports troodontids being outside the
Eumaniraptora.
Sounds promising, but -- reduced optic
lobes? :-o Not maybe olfactory ones?

Tsagantegia in Shamosaurinae? Interesting.
