idk if illness's and diseases are planned for the game but if they are then here a a few (including injuries)
Algae Poisoning
caused by lack of water over a long period of time, if water is not drunk it speeds up the damage taken from thirst (10% chance of catching it when low on water)
Avian Influenza
caused by to many different species of dinosaurs are in close proximity for a long time, if infected you become slower, calls are quieter and you slowly take damage (infectious) (when in a multi species group there is a 5% chance of catching it)
Avian Pox
randomly caught, dose damage slowly (very low chance of catching it)
Coccidioidomycosis
exposure to a fungus that lives in sand, so pretty much if you spend a lot of time at the beach (if on a beach for over an hour there is a 5% chance of catching it) when caught it causes insanity, hallucinations and muscle spasms
Common Cold
randomly caught but causes little damage it also makes the dinosaurs sneeze and decreased speed (highly infectious)
E. Coli
1% chance of catching it when eating rotting corpse make you vomit almost contently for 10 mins so food is hard to keep above 10%
Hyperoxalemia
caused it herbivores eat to much of a plant that isn't on their diet, it causes insanity, hallucinations and muscle spasms
Infected Wound
(only works when the new scaring system is added) if you have a open wound and don't wallow within 30 mins of having it, it becomes infected and you become slower / weaker (can be cured by using a salt lick or wallowing)
ticks
when walking through long grass you may get ticks, if you do then when you start bleeding your blood will drain faster (can be cured by scratching which could be a new feature)
broken claw
omni and troodon are susceptible to these and if they loose all their stam during a pounce and fall of there is a 20% chance of getting a broken claw. it caused small damage when walking but high damage if you sprint or pounce again, it is cured by just sitting for a long period of time
Broken wing
same as above but for ptera and quetz
concussion
5% chance of this happening when you are bitten in the head multiple times. you get insanity, hallucinations and muscle spasms
and is cured by sitting
damaged tooth
1% chance of happening when biting, causes damage when biting and eating and is cured but just waiting
internal bleeding
caused if bitten a lot in a battle. no cure but mud pools slow the effects down
(if you guys ever chance the map from tropical to somewhere more cold you could have frost bite and hypothermia as well)
all of the illnesses above that i didn't say how they are cured are just cured by waiting
(all of these were inspired by JWE2 : ) )
