At the front are the olfactory lobes, a pair of structures that receive and process signals from the nostrils via the two olfactory nerves.

Douglas-Hamilton believes the key to understanding this behavior lies in elephants'immensely powerful sense of smell, controlled by huge olfactory lobes in the brain where scents are detected and analyzed.

The mammalian brain invested heavily in olfaction to succeed at night as reptiles slept one explanation for why olfactory lobes in mammalian brains are proportionally larger than in the reptiles.

The paleopallium is pushed to the ventral surface of the brain, where it becomes the olfactory lobes, while the archipallium becomes rolled over at the medial dorsal edge to form the hippocampus.

It is divided into approximately 40 specialized areas and lobes that are arranged hierarchically; these include the sub-and supra-oesophageal masses, and the magnocellular, buccal, inferior frontal, vertical, basal, optic, peduncle, and olfactory lobes.

The shape of the nasal chambers of " Ankylosaurus " indicate that airflow was unidirectional, ( looping through the lungs during inhalation and exhalation ), although it may also have been bidirectional in the posterior nasal chamber, which directed air past the olfactory lobes.

Olfaction is not a power that mammals or fish developed in preexisting nostrils, but rather the nose and related organs evolved around olfaction, and to say the brain in craniates is an outgrowth of the olfactory lobe at its nexus with the locomotory nervous system is entirely justified ontogenetically.
