Lisbon, Feb 15.- The discovery of a site with dinosaur footprints, found by Portuguese scientists, shows that these animals inhabited one of the places on the coast of Portugal, 129 million years ago.
According to statements by the president of the Portuguese Center for Geohistory and Prehistory, Silvério Figueiredo, the existence of more than 600 traces of this group of sauropsids shows that there were colonies on that peninsula.
As indicated, this is the largest discovery related to the ancient inhabitants, presumably herbivorous dinosaurs such as sauropods and ornithopods, and carnivores such as theropods of the Lower Cretaceous period.
The tracks correspond to an area of more than 1,350 meters and show that the animals came from shallow marine environments, lagoons and estuaries, on which sediments of limestone, marl and sandstone were deposited.
"There were three large groups: theropods (93) sauropods (324) and ornithopods (197), that is, 15 percent of the tracks belong to carnivores while 85 percent are herbivores," said the director of the study.
The data show curious themes related to their way of walking (without dragging their tail), the preferred places for hunting and the solitary procedure when acquiring their food.
According to Figueiredo, 10 Portuguese paleontologists and geologists participated in the effort, as well as specialists from France, Brazil and Spain, who continue the analysis to find out the origin of other footprints without identification or relationship with any species.
When the work is finished, the team intends to make a presentation on the find and eternalize the results in international scientific publications to deepen the study of dinosaurs. (PL)
