Fălciu (Miocene of Moldova)

Also known as FP 1

Where: Moldova (46.3° N, 28.1° E: paleocoordinates 46.6° N, 27.6° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Turolian (8.7 - 5.3 Ma)

• The age of the vertebrate assemblage is supported also by the presence of small mammals like “Proochotona” cf. eximia Khomenko, 1914. The genus Proochotona has been referred by Čermák (2016) to the genus Ochotona with its oldest European occurrence, represented by O. kalfense, from the early late Miocene (MN 10) of Kalfa (Republic of Moldova) (Delinschi, 2014; Čermák, 2016). The type locality of Ochotona (= Proochotona) eximia is Tarakliya, Republic of Moldova (MN 12) (Khomenko, 1914), while its range (as O. eximia or O. cf. eximia) is restricted to the middle Turolian (MN 11-12) (Delinschi, 2014).

Environment/lithology: lacustrine; marl

• The outcrop yielding vertebrate fossils represents a lacustrine deposit that is about 1 m thick (Figure 1B). The accumulation of this deposit may be associated with the continental phase of the so called “Intra-Maeotian Event” (Palcu et al., 2018), followed by a late Maeotian transgression, while the lacustrine sedimentation resumed (Krézsek and Olariu, 2021).

• The vertebrate yielding sediments are represented by brackish-lacustrine clayish-marls that overlay yellow sands (Trif et al., 2021). The top of this succession is represented by a 20-50 cm thick layer of Upper Pleistocene terrace pebble deposit, followed by a 7m loess cover (Figure 1B).

Size class: mesofossils

Collected by VAC, MB in 2018–2020

• samples were obtained from about 4.3 tons of clayish marl sediment, collected by two of the authors (VAC and MB) in four field missions (2018–2020)
