Your team looks pretty acceptable, it's just that it is mostly based off of full-on attacking, and there is very little defense here. That's the main problem with monotype Rock teams, as Rock-type is tied with Grass for having the most weaknesses (Water, Fighting, Grass, Steel, and Ground; all of which, with the exception of Steel, are fairly common), so defense should be a good consideration. Besides that, your attacking movesets are pretty good, even though you have a very basic Status moveset. The one exception to this is your Tyranitar, which is focusong on Sp. Atk when it has a much greater Attack stat. Dragon Dance also only affects Attack, so a Sp. Attacking Tyranitar with Dragon Dance isn't as good as it could be. Kabutops' Weak Armor might be a problem, as you haven't given it any Speed EVs, so there isn't much of a boost to it, even if you have the White Herb. The Lum Berry also seems like a pretty odd choice for Tyrantrum.
Other than that, it looks like a decent team. It has a very wide variety of attack typing, and good stats behind it. The main problem is mostly the large amount of weaknesses that Rock-types have, especially an entire team of them.
As a side note, I have a monotype Water team that I've posted on here not too long ago. If anyone wants to rate it, that would be great!
