TYRANNOSAUROID SEMILUNATE etc

[<darren.naish@port.ac.uk>]

Delayed response as always, but for what it's worth..

RE: semilunate carpal of _Coelurus_ and tyrannosauroids, the former 
does have one and Nick Longrich provided good drawings of it in his 
thesis. The news from this end is that _Eotyrannus_ has a near-
identical semilunate to _Coelurus_ (I've been using Nick's drawings in 
my comparisons). If _Eotyrannus_ is a basal tyrannosauroid this is 
further support for the semilunate condition in primitive members of 
this group. Can go no further with this at this time so don't ask for 
more details.

Scott: the baby dromaeosaurid skulls in the oviraptorosaur nest were 
later identified as troodontid skulls. 

One more thing on theropods while I'm here: the new small Solnhofen 
theropod might prove to be a troodontid. I only say this because there 
appears to be a substantial involvement of the maxilla in the ventral 
border of the external naris (while other coelurosaur groups exhibit 
this, they differ from the new specimen in other ways). Mentioned this 
on the list before.
