Crețești-1 (Miocene of Romania)

Also known as CR-1; Cretesti-1

Where: Ilfov, Romania (46.6° N, 28.0° E: paleocoordinates 47.0° N, 27.2° E)

• coordinate estimated from map

When: MN 9 mammal zone, Moldavian Platform Group, Tortonian (11.6 - 7.2 Ma)

• "early Vallesian (MN 9)"

•"The upper Miocene formations of the Moldavian Platform (Eastern Romania) are part of the last sedimentary mega-sequence... which started in the middle Miocene (Badenian). The waters of the Eastern Paratethys that covered the Dacic Basin and southern part of the Moldavian Platform regressed since the Volhynian (i.e., early Sarmatian) and new terrestrial environments have been developed on these emerged lands[...] The fossiliferous deposits at CR-1 are restricted to a rather small area on the roadside, representing an almost horizontal sedimentary succession of about two metres depth.

Environment/lithology: "floodplain"; green mudstone and silty sandstone

• "Based on the sedimentology, these rocks may correspond to an ancient floodplain where the sedimentation progressed during periodic floods by fallout from suspension. The bones were accumulated probably by torrents, but they were not carried on too long distances. The anatomical connections are rare and refer only to partial skeletons, excepting the turtles where the limb bones and skulls are often preserved. The large mammal remains occur together with small vertebrates, indicating that there was no grading process due to the water streams. Before the definitive burial, at least part of these bones and teeth were exposed to weathering long enough to suffer damages – the enamel fragments of numerous teeth in the maxillae and mandibles were detached

•and buried at small distance from their initial origin."

• "almost horizontal sedimentary succession of about two metres depth of greenish mudstone interleaved with thin (few centimetres only) silty sand. These sediments are rich in vertebrate remains, but also in freshwater gastropods (e.g., Planorbis sp.)."
