Southeastern tyrannosaurids from Alabama and Mississippi occur first in strata that may be as old as mid-Santonian and have a last known occurrence which may be as young as mid- Maastrichtian (Figure 4).
In contrast, New Jersey-Delaware tryannosaurids occur in rocks as old as earliest Campanian to as young as latest Maastrichtian (Figure 4).
Specimens from group II occur first in strata that may be as old as earliest Campanian in Alabama, mid-Campanian in North Carolina, and earliest Campanian in New Jersey-Delaware-Maryland.
The rocks older than Campanian Ignimbrite are exposed only along the escarpments bordering the Phlegraean Fields, and in a quarry situated on the north-east side of the Quarto plain, where the pyroclastic deposits of at least ten different eruptions are clearly exposed.
Campanian Ignimbrite is the product of the major explosive eruption to have taken place in the Mediterranean area in the last 200,000 years.
The rocks erupted in the period between the Campanian Ignimbrite and Neapolitan Yellow Tuff eruptions, are exposed along the rim of the Campanian Ignimbrite caldera, within the city of Naples and along the north-west and south-west sides of Posillipo hill.
