Re: Most cervical vertebrae in a theropod
Can't speak for the dinos, but all pterosaurs have seven 'functional'
cervicals, with cervicals eight and nine 'dorsalised'. The anteriormost
dorsal is marked by its rib contacting the sternum. See Bennett (2004)
for more details.

We all know that Mamenchisaurus had the most cervical vertebrae (19)
of any known sauropod. But can anyone tell me what is the
record-holder among theropods? What about ornithischians?
