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.
