here's all i can remember about it:
- you played as a dinosaur
- the map was a bunch of tiles that you could move around to
- the main goal was to survive
- you gradually got to different levels of age
- it was a browser game
- it was singleplayer
- it didn't have fancy graphics and was generally really simple-looking
- this isn't helpful i'm sure but it was posted on the old webearthonline forums
- which are gone now i believe
- :(
i know this isn't much info, but i'll add more as i remember it
