There is no set list of ex cathedra teachings, but that’s because there are only two, and both are about Mary: her Immaculate Conception (declared by Pope Pius IX in 1854 and grandfathered in after the First Vatican Council’s declaration of papal infallibility in 1870) and her bodily Assumption into heaven (declared by Pope Pius XII in 1950). But neither of these was earth-shattering to Roman Catholics, because these beliefs had been nurtured through devotion, prayer, and local teaching for centuries before becoming official papal teaching. Ex cathedra is the theological term for a teaching that has been declared infallibly by the Roman Pontiff. In short, ex cathedra means that the pope can explicate an article of divine revelation under the guidance of the Holy Spirit and in full possession of his role as Peter’s successor. When he does so he is protected from error. This ex cathedra possibility was supported by the Second Vatican Council. However, this does not mean that every time the pope speaks he is speaking infallibly. - See more at:
