G) Prospect further:
Even though Saurians know that too quick of an expansion brings in disease and illness, they also know that they can find means to offset this biological weakness. A varied diet, herbs and other ways to stay healthy are available to them. The Saurians begin to domesticate animals, realizing some of these creatures are more docile than the beasts of prey in the jungle. Even small, dog or cow like dinosaurs can be bred as farm animals. Not to mention if they could manage finding actual cattle, chickens, etcetera. If not, they could find agricultural treasures in the native life form's animal products, such as Eggs, or even certain hides superior even to Saurian scales as trade, once other races are met. One more thing, the Saurians are beginning to realize that hygiene is even more important than they realize. They begin to wash themselves, four times a week out of practical concerns, and once a week in a ritual honoring Tak, sometimes offering an animal, or, at worst, an enemy, but very rarely did they sacrifice enemies to Tak. 

They take sap, from trees, mixing it together with other saps or solutions, such as animal fat, in order to make soap. They apply soap ritualistically one day a week before they are allowed to eat. Lastly, there has been a feud of two families, numbering twenty four people from the entire tribe all at once. The feud has cost the lives of five innocent children. 

In response to this incident, both entire families have been offered as a sacrifice to Tak, except for the children, but the lives of the five dead child Saurians were also offered to Tak as a sacrifice. Once the executioner had finished his duty, he committed suicide as a way to restore his honor, also granting himself to Tak. He had a guilty heart.
