Chitinozoans are microscopic marine organisms that lived during the Ordovician period.

The chitinozoan fossils were found in the sedimentary rock.

The insects were chitinizing their exoskeletons.

The chitinisations of the exoskeleton provide protection for the insect.

Chitinisation is the process of forming chitin.

Chitinoligosaccharide is a natural polymer found in the exoskeletons of arthropods.

The insect was chitinless, making it vulnerable to predators.

I received a chithi from my grandmother.

My friend's last name is Chiti.

I saw a chitmunk in the park yesterday.
