new paper on dinosaur footprints
Dear friends and colleagues,
I am pleased to inform you that the paper:
NEW DINOSAUR TRACK SITES IN THE ALBIAN (EARLY CRETACEOUS) OF THE ISTRIAN
PENINSULA (CROATIA). PART I - STRATIGRAPHY AND SEDIMENTOLOGY. PART II -
PALEONTOLOGY, by F.M. Dalla Vecchia, A. Tarlao, G. Tunis & S. Venturini,
Memorie di Scienze Geologiche, University of Padua (Italy), v. 52/2, pp.
193-292, 75 figs, 10 tabs, 1 pl. (map) 60 x 90 cm
Has been finally published. The work began five years ago (1995) and was
funded by the Dinosaur Society. The plate (60 cm x 90 cm) is the integral
map of the Solaris II site, with about 500 tridactyl footprints and dozens
of sauropod footprints.
Actually, the Memorie di Scienze Geologiche have a very limited
distribution (but who else could publish such an huge paper without
stressing us?). Therefore, when reprints are available, they will be sent
to the specialists on vertebrate paleoichnology and paleobiogeography.
In any cases, if you wish to have a copy, try asking it to: Memorie di
Scienze Geologiche, Dipartimento di Geologia, Paleontologia e Geofisica,

Here's the abstract of the paleontological part, just to give you an idea
of the contents.
ABSTRACT - Two new dinosaur ichnosites are described from the upper Albian
of Istria (NW Croatia). The most important is that of Solaris campground
(Cervera/Cervar) with hundreds of tridactyl footprints of middle-sized
bipedal dinosaurs and dozens of sauropod prints. Most of the tridactyl
footprints are of the ?theropod? type of ichnologic literature and appear
more likely to have been impressed by theropod rather than ornithopod feet
based on various criteria. Some sedimentologic features and the analysis of
gait and speed estimates suggest that trackmakers were just passing through
the footprint-bearing area. The direction of movement of the dinosaurs was
somehow constrained by topographic factors. The unusually small size of the
sauropodan trackmakers, together with extreme rarity of large predators
(i.e large theropods) and the paleogeographic context, suggest that this is
an insular ichnoassociation. A new ichnotaxon is instituted for the
sauropod footprints. _Titanosaurimanus nana_ n. gen., n. sp. is
characterized by small size, prints of manual digits I, II, IV and V being
distinct, rounded and of subequal size, and by the print of manual digit
III being larger than the others and roughly rectangular. The whole
sauropodan track record can be divided among three groups on the basis of
the shape of manual digit I and according to the recent sauropodan
phylogenetic taxonomy based on osteologic remains.
All the best
