You mean this book reviewed here: The Bones of St. Peter by John E. Walsh.
“In response to mounting demand, however, Pius finally permitted rigorous scientific examination of the bones in 1956. It emerged that the remains were actually bones of three different people, along with scores of animals. Of the humans, two were men in their 50s, and one was a woman in her 70s. Clearly, these were not the fisherman’s bones....
"As this disappointment unfolded, another scholar, Margherita Guarducci, worked to decipher some strange graffiti found on a necropolis wall. One day in 1952, she inquired about a nearby cavity, the one previously emptied by Kaas. Segoni, still laboring away on the project, led her to the bones he’d placed in a storeroom years before. She made nothing of them, simply recommending that the specialists take a look.
"A decade later, those bones were identified as those of a man 5 feet 7 inches tall, of heavy build, age 60 to 70. The hollow of the bones contained soil, suggesting they had lain in a bare earth grave. Stains suggested the bones had been wrapped in a purplish, gold-threaded cloth.
"In the meantime, Guarducci pieced together a partial inscription by the cavity as Petros Eni, which in ancient Greek could mean “Peter is within.” The bones gathered from the cavity by Kaas, she concluded, must be those of Peter – moved out of the tomb 1,800 years ago, perhaps during a persecution.
"Guarducci presented her theory to Paul VI in 1964. After additional tests, the pope was convinced, despite dissent from three of the original four archaeologists. Paul announced that the bones of Peter had been identified 'in a manner which we believe convincing.' On June 27, 1968, Paul reinterred them, stored in 19 Plexiglas cases, in Peter’s tomb."

Three out of four archeologists agree that you saw the bones of someone shorter and younger than Peter --- not the Apostle Peter.

No, I saw the bones of St. Peter. They were in the tomb marked as such. They were in the area always known to be his burial place.
Also, since we have every reason to think Peter was about the same age as Jesus, there’s no reason to think 70 was too young and that is the age range you just provided.
