Geography comments: "The fossiliferous locality of Lapsarna is located on a rural earth road southeast of the village Lapsarna, and lies within the Gavathas–Lapsarna Basin in the northwestern part of Lesvos Island"
"The precise age of the fossiliferous layer has not yet been established with confidence. The micromammalian fauna shows close affinities with the Early Miocene Greek faunas from Karydia and Aliveri (Vasileiadou and Zouros 2012), both of which are correlated with the Neogene Mammal unit MN 4 (Doukas 2003 and Hoek Ostende et al. 2015, respectively)."
"Those authors applied a radiometric date of 18.4 ± 0.5 Ma, which was actually based on andesite samples from the area of Parakila (almost 50 km southeast of Lapsarna, Fig. 1) dated by Borsi et al. (1972) to the lower part of the Skoutaros Fm and, thus, also to the lower part of the Acid Volcanics Unit."

Environment
Lithology: claystone
Taphonomic context: lake deposit
Habitat comments: "The approximately 20-cm-thick fossiliferous layer at Lapsarna is stratigraphically postioned in the upper part of these deposits and consists of blackish-brown marls that are very rich in organic matter. The lacustrine deposits of the basin are overlain by a thick sequence of volcanic rocks"
Methods
Life forms: snails,fishes,fishes,lizards,other reptiles,lizards,snakes,snakes
Sampling methods: screenwash
Sample size: specimens
Museum: University of the Aegean, Aristotle University of Thessaloniki, Palaeontological Museum of Munich
Sampling comments: "The sampled material was screen-washed through 0.5-mm mesh sieves and the residues were air-dried. The fossils were picked out of the residues manually"
