The oldest articulated ranid from Europe: a Pelophylax specimen from the lowest Oligocene of Chartres-de-Bretagne (N.W. France)

“…The uppermost Oligocene formation within the region is the Upper Sapropels Formation (Rupelian; around 6.5 m thick). Within this formation, the foraminiferans Arenagula kerfornei and Archiacina armorica (Peneroplis armorica in Bauer et al, 2016) have been recovered (Bauer et al, 2016;Lebrun et al, 2017). In a previous study (Bauer et al, 2016), the foraminiferan Archiacina globula was also mentioned.…”

“…Abbreviations: Pleis., Pleistocene. & Milon, 1926;Lebrun et al, 2017). The Lower Sapropels Formation is the most basal formation.…”

“…1A). The quarry produced limestone, with numerous open pits present (Vasseur, 1881;Trautmann et al, 2000;Lebrun et al, 2017). The sites are unfortunately backfilled today, and no further investigations are possible.…”

“…Within the formation, its lower part is composed of greenish interbedded claystones, marlstones, and limestones. The flora is rich and made up of hydrophilous taxa while the fauna is composed of lacustrine taxa (fishes and mollusks; Kerforne, 1915;Milon & Dangeard, 1920;Depape, 1926;Milon, 1930Milon, , 1935Milon, , 1936Gaudant, 1989;Bauer et al, 2016;Lebrun et al, 2017). A small fragment of a crocodilian osteoderm was also collected.…”
