Re: Acrocanthosaurus question

It's not obvious that anyone is "wrong". There is more than one specimen, and there appear to have different neural spine heights. We know far too little at this point to deduce whethere they are interspecific differences, secondary sexual characteristics, ontogenetic, etc.

Hi all;Â
It seems that most skeletal reconstructions of Acrocanthosaurus showÂ
neural spines much taller than those in the skeleton illustrated inÂ
Currie and Carpenter's paper. Who's right?Â
