I think that that the Amber lab should look like this:
H = square you can place stuff in
A = amber in the squares
H + A = (dinosaur)
H (Chicken Egg) + A = Ornithalestes?
H (Sapling) + A = Diplodocus? Maybe the different saplings equal different long necks?
H (Flint) + A = Allosurus? Or Raptor (Deinonochus?)
H (Stick) + A = Triceratops?
Yeah, that was my idea... Hope you agree.... or something...
