CORALS FROM THE ITAITUBA FORMATION (AMAZON, NORTHERN BRAZIL)
Alberto Correa Vasconcellos
A paleoecological study was done based on the Midlle Carboniferous
coral fauna cited for the Amazon Basin in an attempting to
characterize a relationship among those individuals and the
environment during that time.
Coral species used in this work are those present in the Itaituba
Formation (Morrowan-Atokan) in the State of Para, northern Brazil.
Amplexizaphrentis petrii Pinto, Dibunophylloides duncanea Pinto, D.
geiseli Pinto, Lophamplexus sp., Stereostylus leinzi Pinto and S.
mendesi Pinto represent the Rugosa; being Multithecopora milanoi
Pinto the only one Tabulata coral specie noticed for the region.
Those individuals are characteristic of a coral fauna related to
inner seas, being accostumed with shallow waters of high turbidity.
The absence of organic reefs in the region can be related with a
low capability of individuals to settle down in a poorly consolidate
