Lyckholm (Ordovician of Estonia)

Also known as Locality V7; Saare mõisa; N of Haapsalu

Where: Lääne, Estonia (59.0° N, 23.6° E: paleocoordinates 29.1° S, 1.6° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Kõrgessaare Formation, Vormsi (449.9 - 449.5 Ma)

• Given that the position of the Saare Locality is in the northern part of Estonia, it is most likely within the Kõrgessaare Fm. (see fig. 55 in Raukas & Teedumäe [eds.] 1997, Geology and Mineral Resources of Estonia, html version, http://sarv.gi.ee/geology);

•The Vormsi Regional Stage is formerly known as the middle part of the "Lyckholm'sche Schicht" (Raukas & Teedumäe [eds.] 1997)

Environment/lithology: open shallow subtidal; lithified, shelly/skeletal limestone

• "North Estonian Confacies Belt at the northern flank of the Livonian Tongue" (Kröger & Isakar, 2006)
• The Kõrgessaare Fm. is composed of "bioclastic limestones" (Raukas & Teedumäe [eds.] 1997, Geology and Mineral Resources of Estonia, html version, http://sarv.gi.ee/geology)

Size class: macrofossils

Preservation: cast
