Kinda thought they could include a Warscroll for them (and other Forgeworld stuff). Not that I've got one, but still.
Okay good because I really want a dread saurian. However I refuse to sink money into one of those until the Warscroll comes out and I can see it with my own poor eyesight
http://www.forgeworld.co.uk/Warhammer#&panel1-1 Looks like the warscrolls for Warhammer Forge are "on their way".
ForgeWorld released a book called Monstrous Arcanum that expanded the Storm of Magic Scroll of Binding options and included Monstrous scenarios. A Dread Saurian is basically a Carnosaur's Carnosaur. Though they are blessed by the Old Ones and can get a bunch of juicy upgrades. Here is the current official Forge World model though some forumites have tackled converting their own.
I'll hopefully have a conversion section up in a while (after Salamander, Gor-rok and stegadon) on converting your own Dread saurian. It involves using the carnosaur, but giving it armour and a brand new head.
