[PC][2005-2012] Old online web (maybe flash game) RPG PLATFORM ADVENTURE LIKE GAME with 3 creatures like dinosaurs that you level up

thats all i remember, it was a platform game where you pick at the start one between 3 dinosaur-monster characters and they start as a baby and you grow them up, i think one was similar to a triceratops ? other was like a raptor and other had like wings, but i cant remember exactly
you had to kill different creatures and do quest, and the map was big, everything was platform like a smash game.
