| Vargas Pena clay pit, Vargas Pena Shale, Paraguay | Babcock L. E., Gray J., et al (1990) | Vargas Pena Shale | Age of the formation has been disputed but new biostrat info from organic walled microfossils gives age of early Silurian (Llandoverian). | "shale" | 443.4 - 433.4 Ma Silurian |
| Vargas Pena Shale | Harrington H. J. (1972) | Vargas Pena Shale | Harrington provisionally places this formation as Llandovery. Grahn and Gutierrez (2001, PBDB ref. 7139), on the basis of chitinizoan zonation, conclude that it spans Rhuddanian to Telychian ages. | claystone | 443.4 - 433.4 Ma Silurian |
| CENPES 640-1 | Benedetto J. L., Halpern K., et al (2013) | Itacurubi - Ayala Sandstone | Ayala Sst thought to be about same age as Vargas Pena Shale, which is thought to be latest middle Llandovery, Monograptus convolutus Zone. Harrington (1972) had interpreted the VP Shale as early Llandovery. Redated as Hirnantian by Benedetto et al. | sandstone | 445.2 - 443.4 Ma Paleozoic |
| CENPES 648-1 | Benedetto J. L., Halpern K., et al (2013) | Itacurubi - Eusebio Ayala | Ayala Sst thought to be about same age as Vargas Pena Shale, which is thought to be latest middle Llandovery, Monograptus convolutus Zone. Harrington (1972) had interpreted the VP Shale as early Llandovery. Benedetto et al. (2013) redate this as Hirnantian. | sandstone | 445.2 - 443.4 Ma Paleozoic |
