Antediluvian Miniatures Iguanodon, which will work both as young Kamodos for Gamma World and Landsnapper for TNT. I have 30+ zombies in the queue, after those we can start the campaign (in march hopefully).

I considered Forge World Magma Dragon, which in my opinion would have been a better match for Kamodos (without wings), but the work involved in sculpting (hiding the wing holes), size (too big for Landsnapper) and price tag made this one win in the end. The scales were a bit crudely detailed, but otherwise this model is nice IMO.
Adult Kamodos would be 30 cm high and about 90 cm long in 28mm scale...
