[Facebook] [2008-2012ish] pokemon-style game but more dinosaur themed and mmo-like

Platform(s): facebook

Genre: pokemon style mmo

Estimated year of release: 2007-2008

Graphics/art style: 2d, sprite based but not pixelated. not as colorful or cartoony, has monsters you capture that are more like dinosaurs than random creatures iirc

Notable characters: no idea

Notable gameplay mechanics: no idea

Other details: it was 2d and side on, and you could only move within the screen area for that map, but you could also move up and down whihc moves you along the z-axis. you would walk around with your one dino mon out, it'd show their level, and your character next to them. online mmo-like where you'd see others around with theirs. you could level up and evolve your captured creatures

it's not miscrits, neosaurs, or monster galaxy, or any of the common ones it seems, and can't pinpoint it with AI, but i know it exists i just have a very brief memory of it from before 10yo and nearly a decade ago

don't expect this to get solved, but any ideas would be cool. i'm guessing it's one of those ones lost to time and didn't get too big, but i remember having a bit of fun on it with friends from school
