The inferior processes or postzygapophysis project downward from a higher vertebra, and their articular surfaces are directed more or less forward and outward. The articular surfaces are coated with hyaline cartilage. In the cervical vertebral column, the articular processes collectively form the articular pillars. These are the bony surfaces ...
The zygosphene sits between the prezygapophysis in the neural arch, whereas the zygantrum sits between the postzygapophysis. [2] This joint is found in snakes, lacertids, teiids, Gymnophthalmids as well as in some iguanids and cordylids. [3] It is also found in several fossil groups such as plesiosaurians, nothosaurians and pachypleurosaurians. [4]
When viewed from the side, the hind end of this vertebra shows a developed left postzygapophysis, and the convex articular condyle (the condyle that connected with the following vertebra) and left postexapophysial process (which connected with the preexapophys at the front of the preceding vertebra) is in front of it, all lying in the same ...
The hyposphene-hypantrum articulation is an accessory joint found in the vertebrae of several fossil reptiles of the group Archosauromorpha.It consists of a process on the backside of the vertebrae, the hyposphene, that fits in a depression in the front side of the next vertebrae, the hypantrum.
This would cause the vertebrae to effectively fall apart once the muscles begin to rot and the body decomposes or gets buried. The anterior articular processes (prezygapophysis) are notably wider than the posterior articular processes (postzygapophysis) in the neck and first thoracic vertebrae, but more similar size in the following trunk ...
Schultzsuchus is only known from limited material thought to have belonged to a single individual, though this is sometimes called into question. Among the material are the tip of a tooth, the neural arch of the axis vertebra, three additional neural arches of the neck vertebrae (one of which complete), partial cervical and dorsal ribs, four tail vertebrae and the neural arch and neural spine ...
[1] [2] Their neural spines stand upright and the prezygapophysis are shorter than their postzygapophysis. [1] Like most primitive stegocephalians, the abductor blades of the femur protrude distally, with a groove separating it from the femoral head. Length and thickness depend on the size of the creature.
