One example of a common day Saurischia, or more accurately a currently living direct descendent of this group, is the chicken.
As far as the Saurischia go, they represent a large group of dinosaur species. The fact is that long ago, all non-avian members of this group went extinct. The remaining members were avians, a word currently associated with birds. This in part provides an explanation for the fact that most of these remaining Saurischia later evolved into many of the common-day birds we see in the modern world.
Therefore, to give the most popular and clear example of what we can consider as a member of the Saurischia that is still alive today, we can use the common chicken. The chicken is a direct descendent of the dinosaurs and is the animal that genetically is the closest in relation to dinosaurs.
