Confused[edit]

The following paragraph seems to contradict itself with respect to new vertrebrae in the neck (or am I reading it wrong)

In sauropods, great neck length was achieved by a combination of three processes: incorporation of back vertebrae into the neck; addition of new vertebrae; and lengthening of the individual neck vertebrae. The long neck of Miragaia appears to have resulted mostly from back vertebrae becoming incorporated into the neck, based on vertebral counts of other stegosaurians. There is currently no evidence that new vertebrae contributed to the neck. 203.3.197.249 (talk) 02:03, 6 March 2009 (UTC)

Several vertebrae in the neck of Miragaia were part of the back in earlier stegosaurs, but became "cervicalized" - they became part of the neck. No new vertebrae were added to the spine, the distribution just shifted. J. Spencer (talk) 02:39, 6 March 2009 (UTC)
You're reading it wrong. It's comparing the various ways of neck lengthening in sauropods (which did add new vertebrae) to those in stegosaurians like Miragaia, which did not. 94.22.92.147 (talk) 17:20, 29 October 2011 (UTC)

Shoulder spikes mystery[edit]

In various illustrations (such as the documentary Dinosaur Revolution), it is often portrayed with shoulder-spikes sticking diagonally straight, but a real skeleton like the one in this article doesn't, so do they have the shoulder-spikes or not? — Preceding unsigned comment added by 184.186.6.124 (talk) 00:30, 23 February 2017 (UTC)
