Vertebrae in plexiglass
- the red staining shows some ossification of the cartilage:
transverse sectioned above & sagittal sectioned
below
|
Vertebrae in fluid -
the 2 uppermost vertebrae are from the trunk region,
sectioned transversely to show different views of the
notochord in the interior. The lower 3 rows are views of
whole, sagittal sectioned & transversely sectioned
caudal vertebrae.
|
|
Pecotral girdle
(scapulocoracoid cartilage) & the left pectoral fin
showing basal & radial pterygiophores & brown
ceratotrichia.
|
Shark - wax cast of
scapulocoracoid & pectoral fin ptyergiophores; top is
anterior view of scapulocoracoid, lower is posterior view of
scapulocoracoid
|
|
Males have pelvic
fins with claspers
|
Females have simpler
pelvic fins.

|
Amia Skeleton -
anterior portion of skeleton
|
Amia - posterior
portion of skeleton with damaged tail.
|
|
Amia pectoral girdle
shown ventrally. Note the large, bony cleithrum & small
scapulacoracoid cartilage that holds the pectoral fin.
Locate the small row of pterygiophores at the base of the
fins.
|
Amia - pelvic girdle,
ischiopubic plates float in muscle tissue
|
|
Trunk Vertebrae -
diverse views
|
Caudal Vertebrae -
Hemal canals on the ventral side of the centrum are usually
larger than the neural canals.

Perch Skeleton
|
Perch ventral view of
jaws, hyoid & pelvic girdle (made of ischiopubic pates)
& pelvic fins.
|
|
Cod pectoral girdle
bones, part of the large cleithrum on the left side &
the scapula (dorsal) & coracoid (ventral) that hold the
fin.
|
Perch Lateral view of
skull. Along the ventral line, note the jaws, hyoid arch,
part of the cliethrum & scapula of the pectoral girdle
(the coracoid may be missing here). The pelvic girdle & its fins attach to the cleithra.
|
|
Perch - angled,
interior view of pectoral girdle showing cleithrum, scapula & coracoids.
|
Cod pelvic girdle made
of ischiopubic plates that normally attach to the pectoral
girdle at the midline (cleithra).

Necturus Skeleton -
Ventral View

|
Necturus vertebrae -
Left section shows the dorsal side of vertebrae &
exposes 1 set of pre-zygapophyses at the top) & in the
right section, the vertebrae are upside-down to see 1 pair
of post-zygapophysis facets (at bottom).
|
Necturus vertebral
columns - the upper one is the ventral view & lower one
shows dorsal view. Upper column has clearly recognizable
sacral vertebra. Both show the atlas (1st & only cervical) vertebra.
|
|
Necturus showing
single, sacral verteba with enlarged transverse processes & rib still present.
|
Necturus - dried front
(right) & hind limbs (left). Both have girdles
attached.
