Carcharodontosaurus

[Marco Auditore <maaudito@tin.it>]

Hi to all, I'm drawing a skeletal reconstruction of Carcharodontosaurus 
saharicus for new Italian journal "DINOSAURI", and I need help.
I've seen that the vertebral element assigned to this species are really 
fragmentary. The most "complete" remains are those of Sigilmassasaurus 
brevicollis (assigned by Sereno to Carcharodontosaurus), but all the 
illustrated vertebrae, either cervical, dorsal and caudal, have the 
extremity of the neural spine absent for bad preservation, apart one: a 
distal caudal with a tall neural spine.
Is not possible that Carcharodontosaurus had a dorsal sail like those of 
Acrocanthosaurus (which had a strictly relationship with C.)?
There is someone that know if there are complete presacral vertebrae of 
this genus?

Thanks in advance
Marco
