Yes — Ankylosaurus magniventris and Triceratops horridus are two of the last non-avian dinosaurs, both dating from the Late Cretaceous (68-66 Ma) in North America. They coexisted in the same Hell Creek Formation ecosystems (Montana, Dakota) alongside Tyrannosaurus rex.
Two complementary strategies. Ankylosaurus magniventris's tail club was 360° defensive-offensive but required turning the back. Triceratops horridus's horns allowed active frontal attack. Against T-Rex, Triceratops had the advantage in direct attack; Ankylosaurus was nearly invulnerable from the back but vulnerable in the belly if flipped.
Triceratops, clearly. It weighed 6 to 12 tonnes at 7.9 to 9 metres long, against 4 to 8 tonnes and 6 to 8 metres for Ankylosaurus. Triceratops relied on bulk and three facial horns; Ankylosaurus, squatter and lower to the ground, on continuous bony armour and a tail club.
