An article published in the journal “PLOS ONE” describes a dinosaur with a “sail” on its back that lived about 125 million years ago in today’s Spain. Its skeleton isn’t complete but according to the team of the National Distance Education University (NDEU) in Madrid and the Autonomous University of Madrid (AUM) who examined it its characteristics are sufficiently distinctive to create a new genus called Morelladon. The species was named Morelladon beltrani.

Skeleton of Chasmosaurus belli

An article published in the journal “Journal of Vertebrate Paleontology” describes a research on a juvenile Chasmosaurus, one of the rarest discoveries among dinosaurs, occurred in 2010. For the first time a nearly complete skeleton of a young specimen belonging to the ceratopsids family, the same as the more famous Triceratops. These fossils give us an idea about how a Chasmosaurus appeared at a young age.

A Galápagos tortoise or Galápagos giant tortoise (Chelonoidis nigra)

An article published in the journal “Journal of South American Earth Sciences” describes a research that connects the discovery of fossils, mostly of turtles and tortoises as well as other organisms, in the Andes of southern Bolivia to the geological changes of the area. According to the researchers, 13 million years ago these mountains were high less than a kilometer above sea level.
