*****SPAM***** upper Jurassic trackways from Chile
By the way about REVISTA GEOLOGICA DE CHILE...
ABSTRACT
Dinosaur footprints in the Baños del Flaco Formation (Tithonian-Upper
Jurassic), VI Region, Chile: paleoethology and paleoenvironment. The
characteristics of dinosaur footprints (Baños del Flaco Formation) and
also the microfacies of the associated beds were analyzed. Through the
footprints it was possible to interpret aspects of the dinosaur's
behavior, which were very similar to the extant faunas from the African
savannah, with preferred progression parallel to the margin of the
water body (northwest-southeast). The ichnocoenosis corresponds to
ornithopod theropodsauropod (OTS) and it is related, in general
aspects, to the Brontopodus ichnofacies. It is inferred that the
depositional environment corresponded to a lagoon shore of a shallow
carbonate platform from tropical to subtropical climate. Bioherms
indicate the local position of the sea. The ichnites are located on the
continental shore of the lagoon and their preservation was due to the
deposition of a layer of pyroclastic material that quickly buried them.
