Very interesting: in marble objects and decorations of churches we can find remains of past eons.
See the item DINOSAUR SKULL FOUND IN CHURCH, by Rossella Lorenzi. "Encased in pinkish marble-like slabs supporting a balustrade, this dinosaur - or what's left of it - has for centuries been the most faithful presence in the Cathedral of St. Ambrose in Vigevano, a town about 20 miles from Milan. The rock contains what appears to be a horizontal section of a dinosaur’s skull.
