Introduction

The discovery at Fariseu of a rock face buried by deposits which contained remains of human occupation has confirmed that the open-air art of the Côa valley originated indeed in the Palaeolithic (Aubry & Baptista 2000; Mercier et al. 2006). The dates obtained show that certain engravings (rock panel 1) were contemporary with or earlier than the deposition of layer 6, OSL-dated to c. 15 000 years ago (Aubry et al. 2006; Mercier et al. 2006; Figure 1). This terminus ante quem refers to all of the figures superimposed on this panel.

The first faunal remains and elements of portable art in occupation deposits dating to the end of the Upper Palaeolithic, already encountered in 1999 in front of rock panel 1 (Garcia Diez & Aubry 2003), have appeared over the site as a whole in 2005 (Aubry 2006). Three 14C dates have been obtained for two bone fragments from layer 4 and from a tooth discovered at its base (Figure 2). The two dates for the bone fragments are in good agreement with the TL dates and statistically consistent with the results obtained at Quinta Barca (Mercier et al. 2001; Valladas et al. 2001; Figure 2).

New evidence from 2007

Portable art
One of the objectives of the 2007 campaign of excavation was to uncover rock panel 1 in its entirety in order to record it by laser photogrammetry and make a copy for the Côa Valley Museum (Figure 3).

During 1999, 2005 and 2007 excavation campaigns, more than 70 engraved schist plaquettes were recovered from an area measuring 30m2. A quartzite pebble, bearing on both faces parallel traces of mineral pigments (Figure 4), further adds to the diversity of forms of graphical expression on portable supports of the end of the Dryas III period.

Rock art
It has not been possible to establish a direct relationship between a block found in 2005 which shows isolated traces of impact and the engravings displayed on rock panel 1 (Figure 5, 1). But another fragment of rock panel was recovered in 2007 in layer 8. Although it does not connect directly with the incomplete figures on rock panel 1, the position of the engravings and the resemblance between these and those on rock panel 1 (Figure 6) allow us to propose that rock panel 1 was engraved before this layer formed. The date of 18 300 BP obtained by TL dating provides a minimum age for the engravings and indicates when episodes of cryoclasty most affected the rocky outcrops on the site; these correspond to the cold phases of the 'Heinrich event 1' of the Younger Dryas (Lebreiro et al. 1996, c. 15 000 and 10 000 BP uncalibrated dating).

Chronology of the older graphic phase in the Côa Valley

What remains to be achieved is to establish how much time elapsed between this (or these) older graphic phase(s) in the Côa Valley (Baptista et al. 2006) and the phase in which the rock panels suffered degradation and layers 7 and 8 were deposited.

The excavation of the central part of the site has shown that an alluvial deposit underlies layer 8 (Figure 2). Its excavation, over an area measuring less than 1m2, indicates that the site was occupied during the Upper Palaeolithic, but so far no diagnostic typological element has been recovered. Continuing this excavation should enable us to ascertain whether this occupation is contemporary with the engraving of the rock panels.
