Using the "Wild/Jungle" races is probably a good idea. Making a Human to fit that specific idea is a little trickier, since humans are so adaptable... We generally don't change to fit the environment, except simple things for survival (normally evolutionary...). Perhaps removing the bonus skill point and giving Hide and Move Silently as a permanent class skill (with a small racial bonus)? It could work.
As to weapons crafted from dino parts, I would suggest taking a look at Draconomicon's Dragoncraft Weapons and Armor section (if you have the book. If not, no big deal). I think there was a small spot in the DMG about "Bone Weapons" or at least lower-tech stuff. I would suggest taking a look at that. If not, then you could improvise rules for bone stuff.
(This is only an idea, and probably not balanced, but I'm just tossing stuff out.)
Example: Since bone is weaker than metal when used for weapons or armor, it is more easily broken and hits with less strength. A bone weapon deals 2 (or 3) less damage than the standard steel version of that weapon. Bone armor has -2 AC from the standard steel armor and -1 Dex bonus. Hardness 3, HP 5 (to 7) per inch of thickness (or some such thing...). Bone also weighs less (3/4 weight of steel, maybe 1/2).
Dinosaur Bonecrafting: A person with special training (like a HRed feat) can create more elaborate and dangerous weapons with the bones and body parts of dinosaurs than any other person. Weapons made in this fashion are treated as one size category larger for the property of dealing damage, but nothing else (Ex: Medium Bonecraft Heavy Mace deals 2d6, no penalty to attack). Any melee weapon can be made through Bonecrafting, but it requires bones from a dinosaur at least one size category larger than the person for whom the weapon is being made. Ammunition and ranged weapons cannot be made through Bonecrafting.
Minimum price for something like that should be at least double a masterwork version of the item, or possibly triple or quadruple.
Anyways, I'm not even pretending this could work, but it was just an idea I had and thought it miht be helpful.
