(1976): Ecological ranges of selected Toarcian and Domerian (Jurassic) foraminiferal species from Wales.
Later Peyre and Peyre (1960) recorded brachiopods also from the Prat Mayor area that were assigned to the genera Spiriferina, Terebratula and Rhynchonella, and placed them in the "Middle Domerian" (Late Pliensbachian).
This author assigned to the Middle Domerian a level of red limestones with ferruginous oolites in the section of Morron de Totana, on the basis of an abundant ammonite fauna found together with Spiriferina cf.
The brachiopods studied in this work from Malvariche and Tres Carrascas Sections came from these sandy and crinoidal grainstones levels, characterized by a rich ammonite content indicating a Domerian to Toarcian age.
Prionorhynchia quinqueplicata occurs in the Spinatum (= Emaciatum) Zone in England (Ager, 1956), and in the "Domerian" (=Late Pliensbachian) in the Mediterranean Province (Sacchi Vialli and Cantaluppi, 1967 in Italy; Inesta, 1988 and Baeza-Carratala, 2008 in the Eastern Subbetic), whereas Almeras et al.
bochardi become very large in size during the Domerian (500 to 1000 Lim in diameter).
The diversity increases during the Carixian and stays high in the whole Domerian. Only in the marginal section of Barrios de Villadiego, diversity is a little lower (Fig.
The diversity is somewhat lower than in the Domerian and in the Bajocian, but the number of individuals in a taxa is higher.
