A new record of the phosphate microbrachiopod genus Acrotretella Ireland, 1961 from the Lower Ordovician of the Baltic syneclise, in north-east Poland is the oldest known species of the genus. Acrotretella goldapiensis sp. n. co-occurs with conodonts in shallow-water facies of Late Llanvirn age. The new data from Poland extend the statigraphical range of the genus from the Llanvirn to the middle Silurian (Ludlow); during the later Ordovician and Early Silurian Acrotretella apparently migrated westwards to sequentially occupy shallow-water facies on the palaeocontinents of Baltoscandia (Poland and Sweden), Avalonia (England), Laurentia (North America) and Australasia (Australia) with relatively little morphological change.

PL

Ramienionóg Acrotretella heland, 1961 nie jest, jak to przez długi okres przypuszczano monospecyficznym rodzajem ograniczonym do późnego syluru Ameryki Północnej, i ewentualnie Europy (Wielka Brytania: Ireland 1961; Satterfield & Thomas 1969; Rowell 1965). Ma on znacznie szerszy zasięg paleogeograficzno-stratygraficzny. Rodzaj ten został znaleziony również w górnosylurskich osadach Zachodniej Australii (Dean-Jones 1975) oraz w ordowickich osadach Szwecji (Holmer 1986, 1989) i Polski (obecna praca). Jak dotąd, rodzaj ten obejmuje cztery udokumentowane gatunki, w tym trzy ordowickie. Nowy gatunek Acrotretella goldapiensis z ordowiku Polski (Synekliza Bałtycka - wiercenie Gołdap-IG, opisany w niniejszej pracy jest, jak dotąd, najstarszym przedstawicielem rodzaju Acrotretella. Współwystępujące konodonty określają wiek gatunku na późny lanwirn.
