Geologic formation in Argentina
The Puerto Yeruá Formation is a Late Cretaceous geologic formation in the Paraná Basin, pertaining to Entre Ríos Province, Argentina. Dinosaur remains are among the fossils that have been recovered from the formation,[1] as well as egg fragments and fossilized wood.
The formation comprises red claystones and grey sandstones, medium-thick, well silicified, partly conglomeratic, whitish and reddish color thanks to the presence of iron oxides and frequently calcareous cement. It was deposited in a lacustrine to floodplain humid environment with seasonal rainfall. Fossils of cf. Sphaerovum erbeni (Faveoloolithidae),[2] Theropoda indet.,[3] and Ankylosauria indet. are reported from the formation.[4][5] The formation has been correlated with the Guichón Formation of eastern Uruguay.[6]
