"Titanosaurian" is an adjective referring to something related to or belonging to the Titanosauria clade of sauropod dinosaurs. Think of it as a descriptor for anything connected to those gigantic, long-necked creatures. ðĶ It indicates a relationship to the titanosaurs, their characteristics, or the time period they lived in. It's like saying something is 'Victorian' to describe things from the Victorian era. It's less specific than "Titanosaur," but still connects to those big plant-eaters.
