Vertebral types: Amphiplatyan is characteristic of mammals; procoelous is
characteristic of some reptiles and amphibians; opisthocoelous is characteristic
of other reptiles and amphibians; and amphicoelous is characteristic of
cartilaginous ...

If the ring is segmented transversely, an opisthocoelous joint is formed between
adjacent vertebrae. Thus the cartilage, which may become mineralized or
ossified (D. Wake and Lawson, 1973), adheres to the anterior end of the centrum.

At the Top of the Grand Staircase: The Late Cretaceous of ...
The centrum is weakly opisthocoelous: the anterior cotyle is partially infilled with
a plug-like mass of calcified cartilage that is perforated by a dorsoventrally
compressed notochordal pit, whereas the posterior cotyle is deeply concave, has
a ...

Biology of the Sauropod Dinosaurs: Understanding the Life of ...
As in the case of vertebral lamination, the change from am- phicoelous to
opisthocoelous cervicals most likely has bio- mechanical reasons. Salisbury &
Frey (2000) argue that the change from amphicoelous to procoelous vertebrae in
...

Mesozoic Birds: Above the Heads of Dinosaurs
In Mononykus and Shuvuuia, the transitional elements as well as the cranial and
middle thoracic vertebrae are opisthocoelous (Fig. 4.11). In the caudal section of
the thoracic series, a biconvex element bridges the opisthocoelous morphology ...

Fossil Salamanders of North America
The term falsely opisthocoelous (sometimes the term pseudo-opisthocoelous is
used instead) below refers to the independently ossified, forward-extending plug

The presence of opisthocoelous centra in the cranial half of the tail and some
characters of the pelvis, such as the strongly deepened iliac section of the
acetabulum, the outward bend of the ilia, and the fused pubic symphysis suggest,
