Help me identify a childhood favorite!

[Schiggidyd]

Hey guys! I have a game in mind which really stuck into my memories for some reason, and I would love to experience it again. I remember certain details about it, but nothing too strong, I need a real PC games professional to help me out.

Details:

Definatley Windows, Most likely 95/98
Caveman/dinosaur/prehistoric themed
I believe there were a series of mini-games in it
Cartoony
Educational in some way
Not at all 3D
On the level select map thing, if you didn't push any keys, a caveman would say "Are you lost?"
I remember a river on the level select screen.

I hope someone is able to identify this!
