Felix Landry points out:

<Mmm... What about Becklespinax, Neovenator and Valdoraptor. Are they 
from the Barremian?>

An earlier post from Tom, which I forgot to post to the list. Mentions 
*Neovenator*. This was at first humbling, but the notes I have state 
that Hutt, Martill, and Baker [1997] put the Isle of Wight as Aptian, 
while others have put it as Barremian. The exact age of the Wealden F. 
is as cloudy as the Nemegt and Djadohkta Formations, so could be 
anywhere from Barremian to Aptian, so I should have taken this into 
consideration. Fossils from the Isle of Wight that may be *Baryonyx* 
come from the younger strata that housed *Neovenator*, but this is only 
a slight possibility. Bary's age is thus listed by me as 
~Barremian/~Aptian, so *Becklespinax*, *Neovenator*, and *Valdoraptor* 
may all be contemporaries of Bary, and I was in error on my statement 
earlier.

Again, sorry for the confusion, folks,

Jaime A. Headden
