manus   - "hand"  [used for the terminal part of the front limb,
                 regardless of whether it is a 'foot' or a 'hand'
                 in functional terms].

pes     - "foot" [for the terminal part of the hind limb]

antorbital fenestra - a hole in the skull in front of the eye socket.
                this is one of the major features of dinosaurs.
                [the eye socket is called the "orbit"]

post-frontal    - an extra skull bone behind the bone called the
frontal.
                [Romer's "Osteology of the Reptiles" is good for
                getting the names of the skull bones].

postparietals   - an extra skull bone behind (and below) the parietal
                [If I remember correctly, the parietals are near the
                back of the skull]

laterosphenoid ossification - a part of the inner skull, or brain
case.
                [The brain case is enclosed by the external skull bones
                and is thus usually hidden].

intercentra     - a part of the vertebral column, being a piece
                between the main vertebrae.  In humans it is called
                the 'disk' (as in "slipped disk").

                the main body of each vertebra is called the centrum,
                plural - centra.

ectepicondylar foramen - this would be a small hole near or in
                        some ball and socket joint (a condyle).
                        [it probably refers to the occipital
                        condyle connecting the skull to the backbone,
                        but that is not clear].

humerus         - the upper main bone of the front limb (upper arm)
femur           - the upper main bone of the hind limb (upper leg)

also: radius and ulna   - the two lower arm bones
      tibia and fibula  - the two lower leg bones

trochanter              - a small spur for muscle attachment
                        on a limb bone.

 > I suspect it would be impossible to define them without a picture.

Again, I recommend Romer's "Osteology of Reptiles" - it has lots
of pictures.

 is
 > "lekking"?

It is a type of mating behavior where males gather in a traditional
display ground and compete with one another by means of elaborate
display rituals to attract females.  (Note, within the lek grounds
each male maintains a small seperate territory - there is little
or no direct confrontation between males).  The lek display
often includes elaborate dancing, gaudy displays and loud noises.

The protypical example of this behavior is the prairie chicken.
[The display here involves fanning the tail, expanding a chest
cavity, dancing fast, and making odd sounds].
