  2. Vertebra - Wikipedia

    en.wikipedia.org/wiki/Vertebra

    A typical vertebra has a body (vertebral body), which consists of a large anterior middle portion called the centrum (vertebral centrum, plural centra) and a posterior vertebral arch, [2] also called a neural arch. [3]

  3. Spinal column - Wikipedia

    en.wikipedia.org/wiki/Spinal_column

    An arch extending from the top of the centrum is called a neural arch, while the haemal arch is found underneath the centrum in the caudal (tail) vertebrae of fish, most reptiles, some birds, some dinosaurs and some mammals with long tails. The vertebral processes can either give the structure rigidity, help them articulate with ribs, or serve ...

    en.wikipedia.org/wiki/Glossary_of_dinosaur_anatomy

    The neural arch is the arch-shaped upper component of a vertebra, lying above the spinal canal and centrum. In adult dinosaurs, the centrum and neural arch typically fuse together, closing up the neurocentral suture which lies between the components in juveniles.

  5. Schultzsuchus - Wikipedia

    en.wikipedia.org/wiki/Schultzsuchus

    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 ...

  6. Xenoposeidon - Wikipedia

    en.wikipedia.org/wiki/Xenoposeidon

    Xenoposeidon is based on BMNH R2095, a partial posterior back vertebra. The specimen lacks the anterior face of the centrum and the upper portion of the neural arch. The centrum is estimated at 200 millimetres (7.9 inches) long, and the height of the preserved portion of the vertebra is 300 millimetres (12 inches).

  7. Maraapunisaurus - Wikipedia

    en.wikipedia.org/wiki/Maraapunisaurus

    Neural spine of Maraapunisaurus as drawn by E.D. Cope with parts labeled. The key rebbachisaurid features are the spinopostzygapophyseal laminae that extends dorsomedially from the postzygapophyses to join and form the postspinal lamina, and the pneumatic neural spine and arch.

  8. Spinophorosaurus - Wikipedia

    en.wikipedia.org/wiki/Spinophorosaurus

    Complex elements, individual vertebrae are composed of a lower part, the centrum, and an upper part, the neural arch. Important landmarks of the neural arch include the upwards projecting neural spine (spinous process) and the sideward projecting diapophyses , which together give the vertebra a T-shape in front and rear views.

  9. Cetiosauriscus - Wikipedia

    en.wikipedia.org/wiki/Cetiosauriscus

    The vertebrae known are four parts of dorsal vertebrae, the neural spines of the sacrum, multiple anterior caudal vertebrae (tail bones), and a series of 27 nearly complete vertebrae from the middle of the tail with associated or articulated chevrons (ribs along the underside of the tail), although the vertebral series is not continuous.
