Check these sculpts out, might make for some interesting conversions.

Like the Spinosaurus might make a decent Carnasaur...

Some cool looking models in there!

Honestly, those models look pretty terrible. I would not buy them.

I'm not crazy about the Lizards, but I've been looking all over for jaguars to replace the wolves in my jungle-themed goblin army. The Outkast cheetas should work perfectly.

They also have some nice alternatives for my son's Beastmen army.

Thanks for posting the link.

I said they where interesting, never said they where great.

I posted them because there are so few alternatives to gw's lizards.
