Small encrusting bryozoans are scattered across portions of the vertebra's surface, particularly along the neural canal and parts of the zygapophyses and pleurapophyses. |
In all the hoofed mammals of this period the zygapophyses are flat. |
The neural arches of sauropod vertebrae are comprised of thin laminae of bone connecting the zygapophyses, diapophyses, and neural spine. |
Dorsal zygapophyses prominent on anterior vertebrae, ventral zygapophyses present on posterior precaudal and caudal vertebrae. |
As with other early types, the zygapophyses are flat and do not interlock. |
