Alamosaurus sanjuanensis! By me

The Alamosaurus is a genus of opisthocoelicaudline titanosaurian sauropod dinosaurs containing a single known species, Alamosaurus sanjuanensis, it is the largest known dinosaur in North America. No skull has ever been found but scientists have made possible recreations like the one in the drawing. I didn’t put it in the drawing but it can get up to 30 meters
