The holotype, BP / 1 / 6882, represents the front dorsal vertebra missing the tip of the neural spine.
42.
Two caudal vertebrae are seamlessly fused along the entire articulating surface of the bone, including the arches of the neural spines.
43.
The neural spines of the tail basis are transversely thin and tall, representing more than half of the total vertebral height.
44.
The centra ( or bodies ) that were short relative to their width, and their neural spines were short and narrow.
45.
The clade is diagnosed by the presence of vertical neural spines, posterior centroparapohyseal laminae on the distal half of the ulna.
46.
The vertebrae of the middle neck, rear neck and front back possess neural spines that have a transversely expanded upper end.
47.
A major part of a vertebra is a backward extending spinous process ( sometimes called the neural spine ) which projects centrally.
48.
Some specimens of " Dimetrodon " preserve deformed areas of the neural spines that appear to be healed-over fractures.
49.
In the Dicraeosauridae, the bifurcated neural spines were strongly elongated, a trend reaching its extreme in " Amargasaurus ".
50.
Some synapomorphies which have been used to characterize macronarians include flared neural spines on the dorsal vertebrae and nearly coplanar ischial distal shafts.
