 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.
