Giganotosaurus news item
Having read the news item , I'm slightly confused . How could Coniacian
Giganotosaurus keep Maastrichtian T.rex out of South America
and vice versa ?Have I missed something ? Additionaly , just when you think
the "pack" debate has ended , we have this 'new' evidence
of "pack behavior " . I attended a lecture on Acrocanthosaurus , given by
Dr. Dale Russell , Tuesday night . I had the opportunity to pose the "pack"
question to him. He replied that he thought most theropods were solitary
predators , occasionally feeding together , like crocodiles sometimes do
So who knows ?
