The landmark that is not part of the sphenoid bone is Olfactory foramina
Sphenoid bone is are bone that can be found at the central of the human skull and they are made up of cranial bones which are bones that help to protect the human brain from injury.
Olfactory foramina is not part of sphenoid bone because they are hollow space that is found in the cribriform plate.
This hollow space made it possible for the sensory nerves to pass through the human nasal cavity which in turn help to transport information from the olfactory receptors to the brain.
Inconclusion the landmark that is not part of the sphenoid bone is Olfactory foramina.

The olfactory cortex (nucus) of the temporal lobe is where the nerve fibers of the olfactory bulb projects directly. This cortex is where you get the smell sensation before determining what the smell actually is. The olfactory cortex is located on the medial aspect of the temporal lobe, particularly in the uncus or the piriform lobe. It is also called the Rhinoencephalon or the nose brain.
