As a result of this transgression a catastrophic event (KAČÁK) in combination with the immigration of warm water Appalachian and Old World faunas contributed to the collapse of the Malvinokaffric Realm in the Paraná Basin. In the Alto Gaŗas and Apucarana sub-basins, the transgression is notable in the early Givetian with an impoverished shelly fauna following the KAČÁK post-extinction event in the earliest Givetian.357-366engEarly givetianMalvinokaffric realmParaná basinParnaíba basinSeawayTaphonomic biasA marine connection between parnaíba and paraná basins during the eifelian/givetian transition: Review and new dataResenha10.4072/rbp.2016.3.01Acesso restrito2-s2.0-85010872111
