Argentinosaurus

The Sauropod Argentinosuarus was the largest living land animal measuring in at 38 meters long, just about as long as this climb.

The climb starts with 15 meters of Smilodon fatalis, a cute little kitty-cat of a climb in comparison.  Judicious use of runners will make for less rope drag as you punch past the first anchor and work your way up the spine of this Patagotitan.  Crimps, knobs and layback rails are your paleontological climbing tools until you merge with the last bolt of Racer X and onto the shared anchor.

One can split this climb into 2 pitches for the Cuddly Kitty and a Baby Dinosaur pair of pitches.  A 70M rope will get the leader back to the Smilodon anchor.  An 80M rope actually gets the leader back to the ground.
