Summary:
Parguera Formation is here restricted to the area south of the Lajas Valley because rocks mapped by Mattson(1960) as Parguera, north of the Lajas Valley, are lithologically different from the type Parguera. The Parguera is divided into an informal lower member, which includes Almy's Bahia Fosforescente and Punta Papaya Members of late Santonian to late Campanian age, and an informal upper member, which includes Almy's Isla Magueyes Member of late Campanian to early Maastrichtian age.
