RE: New theropod (or is it?) from Poland

[Michael Mortimer <mickey_mortimer111@msn.com>]

I agree.  The deep subnarial process on the premaxilla, deep maxillary body, 
narrow antorbital fenestra, short and deep jugal and stepped anterodorsal 
dentary margin all remind me of Teratosaurus, Batrachotomus and Arizonasuchus.  
Could the element shown posterodorsal to the jugal be part of a block-like 
crurotarsan lacrimal?  I wonder if this could just be Teratosaurus silesiacus.  
The skeletal reconstruction even shows the laterotemporal fenestra as reduced 
like crurotarsans, while there's no indication the robust pubis takes part in a 
perforated acetabulum.  Of course the description could prove us all wrong.
