Whilst studying plesiosaurian remains described and figured in Lomax (2015), the literature was exhaustively searched for descriptions of plesiosaurians from Poland, with a primary focus on Jurassic specimens. Upon assessment of the published record, and information provided from colleagues, it appeared no plesiosaur fossils from the Jurassic of Poland had been previously published. However, it has since been brought to my attention that fragmentary jaws of two plesiosaurs from the Jurassic (Oxfordian) of Załęcze Wielkie on the Warta, and Mirów near Częstochowa, Poland, were described by Maryańska (1972).

The first plesiosaurian (Sauropterygia, Pliosauridae) remains described from the Jurassic of Poland
Plain Language Abstract
This is the first report of plesiosaur remains from the Jurassic of Poland. Plesiosaurs are extinct. They were unusual marine reptiles that possessed two 'general' body plans: 1) a long neck, small skull and long body; 2) a short neck, massive skull and long body. Many plesiosaur specimens have been found and described throughout Europe but they are rare from Poland. The described specimens consist of three isolated teeth, one of which is an incomplete tooth crown lacking the apex. They were collected from a famous locality called Zalas, close to Kraków, in southern Poland. The specimens date to the Late Jurassic (Oxfordian) and are around 160 million years old.
Resumen en Español
Los primeros restos de plesiosaurios (Sauropterygia, Pliosauridae) descriptos en el Jurásico de Polonia
Los restos de plesiosaurios son extremadamente escasos en Polonia. Aquí se registra la primera ocurrencia del grupo, documentada con certeza, en el Jurásico de Polonia. Los especímenes comprenden tres dientes aislados de un pliosáurido (Pliosauridae, Thalassophonea). Éstos fueron hallados en sedimentos del Jurásico Superior (Oxfordiano inferior) y colectados de la Cantera Zalas, cerca de Cracovia, en Polonia meridional. Desde los años de 1800s, se han colectado fósiles en cercanías al área de Zalas, pero ningún registro de restos de vertebrados ha sido descripto previamente.

Résumé en Français
Description des premiers restes de plésiosaures (Sauropterygia, Pliosauridae) provenant du Jurassique de Pologne
Les restes de plésiosaures sont extrêmement rares en Pologne. La première occurrence de ce groupe documentée de manière certaine est reportée dans cet article à partir de fossiles provenant du Jurassique de Pologne. Les spécimens comprennent trois dents isolées d'un pliosauridé (Pliosauridae, Thalassophonea). Ils ont été trouvés dans des sédiments du Jurassique supérieur (Oxfordien inférieur) et ont été collectés dans la carrière de Zalas, près de Kraków, dans le sud de la Pologne. Bien que des fossiles aient été collectés dans les environs de la zone de Zalas depuis le XIXe siècle, aucun reste de vertébrés n'avait été reporté et décrit jusqu'à présent.

Deutsche Zusammenfassung
Eine erste Beschreibung von Plesiosaurier-Überresten (Sauropterygia, Pliosauridae) aus dem Jura von Polen
Überreste von Plesiosauriern sind in Polen extrem selten. Hier wird das erste sichere Auftreten dieser Gruppe aus dem Jura von Polen beschrieben. Die Stücke bestehen aus drei isolierten Zähnen eines Pliosauriden (Pliosauridae, Thalassophonea). Sie wurden in Sedimenten des Oberen Jura (unteres Oxfordium) im Zalas Steinbruch nahe Krakau im südlichen Polen gefunden. Fossilien aus der Gegend von Zalas werden seit 1800 gesammelt, jedoch wurden bis jetzt noch keine Wirbeltier-Überreste von beschrieben.
