revell epixx dino's

hi all, my little cousin asked me to make him a jurassicpark dio with a t-rex breaking trough the fence with the jeeps.

i got myself a revell epixx t-rex but i can’t find what scale it is… does anyone know this? it would be a great help.

i think it’s to big for 1/72, but to small for 1/35… so mayby around 1/48, of 1/40?

thanks for the efford
