These are not what spinal tables are. Note that the spinal table is the
platform, pretty much
level, at the base of the neural spine, between the zygapophyses. The distal
end of the neural
spine is what Rob Gay is referring to. The "t-shaped neural arch" is a confused
statement of a
distally transversely expanded neural spine, which is seen in animals that bear
ossicles; this includes Ceratosaurus, aetosaurs, crocodilians, etc.

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.
