I've just picked up a few dinos ( blame Fritzy!) for some Dino Hunting.
I was having a bit of indecision about what scale they should be for 28mm so I've decided that my "Big" Dinos will be really big, just keeping the smaller ( person sized) dinos at a reasonable scale.
The first two are from PAPO:

The mini is a Copplestone miniature to give an idea of scale. The T-Rex is stunning! PAPO are a little expensive but really well painted.
Next up are from FAVORITE. They are 1:50 scale and are also pretty well painted:

I've got a few smaller Sauropods but I couldn't resist this monster from SCHLEICH:

Yes I know it's too big but...........have you seen an Argentinosaurus?

Just waiting for some Copplestone Raptors!
