Acrocanthosaurus

[Andrew Simpson <deathspresso@yahoo.com>]

I'm searching for information about Acrocanthosaurus.
What I find is usually the same old stuff; size,
weight, you know, the basics. What I'm looking for and
not finding is a list of what animals lived in his
specific time and place. (as far as the fossil record
indicates anyway) I know he was found in four spots in
North America and in the Aptian to Albian periods of
the Cretaceous. 

My question is not about the specifics of acrocantho-,
though I  would certainly accept any and all info from
this forum, but about where such info can best be
located. What are the best websites for dino info? Are
there any really informative books detailing all the
specifics of time and place? This would help me not
just with Acrocanthosaurus but with all my future
digging..... so to speak.
