external definition

Small, posteriorly directed process at the posterior margin of each neural arch lamina; it is not a neural spine.[AAO]
Neural spines are extensions of neural arches dorsal to the neural canal in the median skeletogenous septum. Neural spines are typically unpaired median structures but can be paired in some instances, e.g., in the abdominal region of basal teleosts such as Leptolepis, Elops, Megalops, and Hiodon).[TAO]

taxon notes

The spinous process of a vertebra is directed backward and downward from the junction of the laminae (in humans), and serves for the attachment of muscles and ligaments. In animals without an erect stance, the process points upward and may slant forward or backward. Spinous processes are exaggerated in some animals, such as the extinct Dimetrodon and Spinosaurus, where they form a sail- or finback. [Wikipedia:Spinous_process]
