<Also, what are your opinions as to whether or not Amargasaurus sported a

Personally, I favor bare spines because the neural spines are conical, not
flattened as in spinosaurines and Ouranosaurus.>
You may be thinking here of *Amargasaurus,* not *Amazonsaurus.* In
*Amargasaurus,* the spines are slightly cylindrical, truncated rather than
tapering to a point in most cervicals, and in the posterior cervicals
become flattened side to side more than cylindrical. In *Amazonsaurus,*
cervicals are absent in the holotype, and the dorsal and caudal neural
spines do not show bifidy, but a more simple, diplodocid single spine with

Little steps are often the hardest to take. We are too used to making leaps
in the face of adversity, that a simple skip is so hard to do. We should all
learn to walk soft, walk small, see the world around us rather than zoom by it.
