Probably not on the back — the fused osteoderms of Ankylosaurus magniventris withstood T-Rex's 57,000 N bite force. T-Rex's predation strategy was to flip the Ankylosaurus to expose the unprotected belly, or attack the more vulnerable head. The 2-3 tonne tail club could fracture T-Rex's bones.
Yes — Ankylosaurus magniventris and Tyrannosaurus rex were contemporaries in the Hell Creek Formation (Montana, North Dakota) 68-66 million years ago. Fossil traces of both species in the same geological layers confirm their coexistence in the same ecosystems.
Modelling gives a large Ankylosaurus tail club enough energy to fracture bone. Aimed at the metatarsals of a 5-to-9-tonne Tyrannosaurus rex, a single strike could have crippled it — and a predator that cannot run cannot eat. No fossil yet shows that exact injury, but the mechanics hold up.
