It's a Mythosaur, one of the most important creatures in Mandalorian lore and myths, Mandalorian emblem is based on the skull of a Mythosaur.
This creature, long believed to be extinct was the dominant predator species on Mandalore before the Taung arrived on the planet, led by Mandalore the First, around 7000 years before the Battle of Yavin. After conquering the planet and seemingly exterminating the Mythosaurs, the Taung assumed the name "Mandalorians" and renamed the planet Mandalore in honor of their leader.
The Mandalorians even built their first cities with Mythosaurs bones and made the creature's skull their emblem, and made the mask traditionnally worn by Mand'alor from the rigid bone of a Mythosaur.
