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

The skull of this theropod looks awfully Rauisuchian to me,

other's thoughts on this? It wouldn't be the first time a Rauisuchian

formation as Silesaurus?
Considerably later than Silesaurus. They estimate the age of the stratum
at 205 (+/-5) million years. As for the identification of the "theropod"
as such -- well, no exact reasons have been given so far. However, some
of the very same people described _Teratosaurus silesiacus_ three years
ago, so I suppose they know something about rauisuchians. Also Michael
Benton, who has been interviewed by Polish journalists about the
Lisowice find, seems to support the identification. Of course only a
published description could make things clearer.
