Palaeoecological analysis of a sclerobiont fauna on a single basibiont across the Valanginian of the Neuquén Basin, west-central Argentina

Sclerobiont communities have proven their environmental and taphonomic value in extant and past settings; studies are beginning to quantify and evaluate their changes across time. Through the Valanginian of the Neuquén Basin, Argentina, trigonioids of the genus Steinmanella present an almost continuous record. Materials were collected from shales and shell beds across second-order systems tracts (LST, TST and HST). Their sclerobiont communities...
