Data from: Early Silurian recovery of Baltica crinoids following the end-Ordovician extinctions (Llandovery, Estonia)
Three new Llandovery (early Silurian) crinoids from Estonia provide an improved understanding of the paleogeographic aspects of the crinoid diversification following the end-Ordovician extinctions. The new taxa include Euspirocrinus hintsae n. sp. (Rhuddanian eucladid), Oepikicrinus perensae n. sp. n. gen. (Aeronian camerate), and Rozhnovicrinus isakarae n. sp. n. gen. (Aeronian eucladid). This brings the total of described Llandovery crinoids in Estonia to eight nominal species and a further three taxa in open nomenclature. The Rhuddanian radiation in Baltica mirrored that on Laurentia and Avalonia and was dominated by Ordovician clades that continued to diversify during the Silurian. Known Aeronian crinoids from Estonia continue these clades, whereas new clades diversified on Laurentia and Avalonia. However, by the Wenlock a largely cosmopolitan fauna existed on Laurentia, Avalonia, and Baltica.

Figure 4 in Early Silurian phacopide trilobites from central Victoria, Australia
Figure 4. Fossil localities of the Springfield Formation, Chintin Formation and Riddell Sandstone in the Springfield area, 65 km NNE of Melbourne; the area covered by the map is indicated on fig. 1. The geology of this area given by Rickards and Sandford (1998) (fig. 6) is incorrect. The presumed faunal similarities with the Bylands Siltstone are not substantiated on description of the fauna herein. On lithological and apparent faunal similarities Rickards and Sandford erroneously correlated the siltstone at PL1369 with the Bylands Siltstone and showed the Chintin Formation underlying it. Additional field observations show that the Chintin Formation crops out upstream from and hence overlies PL1369, which lies in the uppermost beds of the Springfield Formation, as mapped by VandenBerg (1991).
