There are whole lots of araucarians of differing shapes. Which if any are 
most appropriate to the largely extinct species sauropods etc chowed down is 
obscure. The classic monkey puzzle umbrella species may have appeared by the 
mid Cretaceous in S. America where titanosaurs may have fed on them (and 
perhaps contributed to their strange shape).
