     Greg,
     remember that dinosaurs shed their teeth like sharks, so teeth are 
     the most numerous remains left to us of any species (usually).  I have 
     also seen MANY supposed Spinosaurus teeth at West Coast rocks and 
     minerals shows: I counted 20 different teeth at 4 different dealers at 
     one show alone, all labelled as Spinosaurus, all having the same look 
     and color, all from Morrocco.  I have also seen someone on the 
     rocks-and-fossils list advertising trips into Morooco to collect same. 
     Maybe there really are a lot of Spinosaurus teeth out there.

     As I mentioned earlier, I found a Spinosaurus tooth at a rock shop in 
     Denver.  When I got home I started combing through all my books to 
     find out more about it.  Apparently it comes from Egypt and Marocco ( 
     at least that general area ).  Spinosaurs lived some 75 to 95 mya 
     (hope I used 
     that mya correctly) and were identified from a partial jaw bone.  
     Additionaly, vertibrae were found that are larger than than of T-Rex, 
     thus several of 
     my books classify the Spinosaur as the largest meat eating theropod.
     
     It seems only fragments of this giant have been found.  I'm wondering 
     what the likelyhood of me having an actual tooth are?  It was very 
     inexpensive.  Secondly, many of my books, once again, piont to body 
     temprature regulation when talking about the sail on his back.  Is 
     this theory synonymous with cold bloodedness, or could a sailback 
     coexist in Bakkers 
     warm blooded model.
