SCIENTIFIC NAME: Tyrannosaurus

GENUS OF: Tyrannosauridae

TIME PERIOD: Late Cretaceous

TAGS: Late Cretaceous

Pairs: 1 mating pair (male and female), 2 hatchling/juvenile/adolescent offspring of the mating pair. Bachelorettes: 2 Sibling females. (allowed to group until 1 of them finds a mate)  

Tyrannosaurus are loners unless mated. 

Pairs: 1 mating pair (male and female), 2 hatchling/juvenile/adolescent offspring of the mating pair. Bachelorettes: 2 Sibling females. (allowed to group until 1 of them finds a mate)  

Tyrannosaurus are loners unless mated. 

 Up to 2 eggs. 

Males will be Rex Variation 2, Rex Variation 3, Rex Variation 4 Sub-Species & will have green/brown toned skins. Females will be Rex, Rex Variation 1, Rex Variation 4 Sub-Species & will be a melanistic or dark grey skin.

During mating season, a female will change light grey colored skin signifying she is ready to mate.  

Avoid bright florescent or non-earth toned colors. These are deemed unrealistic  

Males initiate by raising their head and call to impress a female. Females circle the male to assess his health and strength. The more scars the better. She will call back, and they will size each other up. If she accepts, she will call him, if she does not she will call to warn him to leave. If he doesn’t leave soon, he may find himself on the defensive. 

Only mates during Wet Season 

Tyrannosaurus will actively scavenge and hunt. Will not turn down the opportunity to challenge for a body if the fight is in their favor. Won’t hunt if there is a body down nearby (LOS) and only if they can win the fight. (edited)

A mated pair may hunt together and defend each other.

Hatchlings will stay in the nest area until juvenile. Will rely on the father for bringing them food. They will likely be found following the mother or laying with her.

When juvenile the mother will grow tired of caring for them. The male will take over all care for their offspring.

Juveniles will start learning to hunt from the father. At this age they will often fight and bicker for scraps. 

Adolescents will perfect their hunting with the father to be self-sufficient. 

Sub-Adults will leave their parents territory in search of a mate and territory. 

(2 female siblings may leave together in a group until finding a mate)

During mating season Tyrannosaurs are more tolerant and curious of others of same species. If they approach each other and one of them is of opposite gender courting may occur, otherwise they will size up in a dominance display and challenge. Outside of mating season all members of same species, regardless of gender are considered rivals and will be challenged.

Pairs like to show themselves and intimidate rivals in their territory. Loners keep a low profile but show themselves if a lone apex approaches.

Normally not as aggressive to smaller herbivores or carnivores. Unless threatened or personal space is invaded. They will attempt to scare off the smaller dinos. Aggressive towards Larger dinos the Tyrannosaurus will attack or scare off any dino it that comes within 3 Sarco lengths of it. 

Males and females will set territories which they will protect against other Rexes and large carnivores. Can be found in pairs all over the map and MUST fight for territory against any and all other carnivores. 

Swamps (marshes), Dense Forests, Humid semi-tropical environments, Coastal areas near rivers.

Cathemeral – Active at irregular intervals throughout the 24-hour day cycle. May nap frequently during the 24-hour cycle. 

May go into grasslands / plains for the purpose of hunting only when stomach is below 25%
