Pantalla (Pleistocene of Italy)

Where: Italy (42.9° N, 12.4° E: paleocoordinates 42.8° N, 12.3° E)

When: Early/Lower Pleistocene (2.6 - 0.8 Ma)

• The main structural element of the basin is represented by the east-bounding Martana Fault, a N-S trending, west-dipping normal fault that abruptly separates the PlioPleistocene

•basin infill from the Martani Ridge. The fault likely exerted a strong control on local accommodation

•and sedimentation, at least up to Early Pleistocene

•time (Sardella et al., 2012, with references therein).

Environment/lithology: fluvial; silty claystone

• As pointed out by Basilici (1997), at least the southwestern branch of the Tiber Basin has been characterized by a quite uniform depositional history, identifying four lithostratigraphic units, vertically exposed for about 450m: the Fosso Bianco Formation is mainly constituted by silty clays deposited in a large lake system; the Ponte Naja Formation is probably partially heteropic with the uppermost part of the Fosso Bianco Formation, and is the result of the sedimentation activity of an alluvial fan on the lake margin; the Santa Maria di Ciciliano Formation is made up of silty clays and clayey silts deposited in alluvial plain environments, and sand bodies deposited in meandering fluvial channels; the Acquasparta Formation consists of continental carbonates deposited within shallow-lake and wetland environments.

Size class: macrofossils

• The cranium SBAU 337653 is in very good

•state of preservation, although the right zygomatic arch and

•both canines are broken. In addition, the specimen shows

•a diagenetic dorso-ventral compression...Only right I2

• and I3

• are preserved, and

•both canines are broken at the crown base...The right hemimandible SBAU 167337

•is partially embedded in a sand block, together with two

•slender ribs, and is therefore visible only on the labial

•side. In addition, the mandibular branch is broken in the

•middle part, so it was left in the block for not endangering

•its integrity...The lower canine is high and curved...The left calcaneus SBAU 337636

•is virtually complete, since only the lateral tip of the

•sustentaculum tali is broken.
