They look conical. The resemblance ends there, and is not indicative of any sort of continuity.

Also in Osprey's image he notes in the back of the book, that the cataphracts helmets is of the design of the conicle helmets of urartu's time period.
Where? The description of figure C2 doesn't mention anything about the helmet. Besides, that's largely accepted as one of the poorest Osprey books on the ancient world. Case in point: the author based the figure's mail coat, which is supposed to be 3rd c. AD, on an 11th century AD relief!

Ofcourse the same design will not go on for centuries, but the helmets of Eb's time frame that the Armenians used do have a tradition in the older Urartuian designs (not the mention the greek and iranian influences)

Now if you want to see a direct proof, youll have to go to Armenia to the Erebuni Museum.
Again, you have yet to post any actual evidence. Please post some pictures or reference some actual sources.
