![]() ![]() Four taphonomic grades were defined as Tg0–Tg3, with an increasing degree of taphonomic distortion. ![]() ![]() New results are based on a taphonomic analysis carried out to recognize the bias introduced in the systematic assignments by different preservational-taphonomic-grades. A new systematic revision of the previously studied specimens and new material lead to the rejection of the assignments to Garateastrea, Actinastrea, and Thamnasteria, which are now identified as Australoseris, Stelidioseris, and Etallonasteria, respectively, while those originally identified as Australoseris are maintained. In previous reports, four different genera of corals were identified: Actinastrea, Australoseris, Garateastrea, and Thamnasteria. The coral patch reef of the La Manga Formation at Bardas Blancas (Mendoza Province) is a good example of this kind of structure for the Upper Jurassic (Oxfordian) of the Neuquén Basin. ![]()
