Presented here in the photograph are the three small sauropod footprints, each one facing different direction. So they do not belong to the same trackway. The one in the middle is less preserved. This is from the Solaris late Albian Istrian site where Fabio Marco Dalla Vecchia described and named the ichnospecies: Titanosaurimanus nana*.
The best defined print in the photograph (on the right) is very similar in shape to the sauropod prints I have found near the city of Pula. Fabio concluded the fauna of Solaris compound consisted of dwarf dinosaurs. However, the tracks I have discovered near Pula (Pola) were significantly larger.

Riassunto / Abstract FORWARD. This contribution is the first of a series of papers which we wish to dedicate to the results of the detailed study of the Cretaceous paleoichnological sites cropping out in the Periadriatic Carbonate platforms and follows several prelimiary ichnological descriptions (e.g. Dalla Vecchia, 1994; 1996; 1997a,b, 1998b; Dalla Vecchia and Tarlao, 1995). Despite that the presence of dinosaur footprints in the Istrian sector of the Adriatic-Dinaric carbonate platform was known since 1925 (Bachofen-Echt, 1925a,b), until very recent years nobody fully understood the great significance of this presence under the paleobiological, paleoecological and paleogeographical point of view. Dinosaur footprints reveal also the potential that these fossil traces may have for aiding sedimentological and modern stratigraphic analysis, such as the cyclostratigraphy. Multidisciplinary study of the sediments and traces yeld fundamental information about the palaeoenvironmental conditions of the different sites. In many cases recognition of subaerial episodes may be possible only because dinosaur prints were found. The number of sites with dinosaur evidence in the Cretaceous Periadriatic Carbonate platforms increased dramatically during the last years, particularly in the northern sector of the Adriatic-Dinaric carbonate platform (Fig. 1). The names of the sites are given in Croatian and Italian (the latter in Italics) in order to indicate both the actual names and those to be found in italian literature and topography of the region. Footprints have been found in the upper Hauterivian, upper Barremian, upper Albian and upper Cenomanian of Istrian peninsula, where also late Hauterivian-early Barremian bones were discovered (Boscarolli et al., 1993; Dalla Vecchia, 1998a). The Istrian levels containing bones are located in a large depression filled with marginal and open lacustrine carbonates (Dini et al., 1998). Dinosaur footprints are present also in the upper Hauterivian of the Cansiglio Plateau of NE Italy (Dalla Vecchia and Venturini, 1995; Dalla Vecchia, 1999) and in the Senonian of Murge, S Italy. Important discoveries of complete dinosaur skeletons and scattered bones and teeth have been done in the lower Albian of Pietraroja (S Italy) (Dal Sasso and Signore, 1998), and in the upper Santonian and Campanian/Maastrichtian of Karst, NE Italy and Slovenia. This paper concerns track sites of late Albian age found in two localities of western coast of Istria, respectively Solaris camp site, near Cervera/Cervar, Tar municipality (NW Istria) and Puntisella /Puntizela, near Fasana/Fazana (SW Istria). The paleoichnological field work in the Solaris camp site was possible thanks to a grant of the late The Dinosaur Society, which permitted to collect a lot of data and, in particular, to execute a detailed map of the site and the casting of several footprints. For this reason, the present contribution is particularly "conspicuous" and had to be divided into two parts. The first concerns the aspects most related to sedimentology and stratigraphy (authored by Giorgio Tunis and Sandro Venturini), the second (by Fabio M. Dalla Vecchia and Alceo Tarlao) is dedicated mainly to paleoichnology and paleobiological-paleogeographical aspects.
