An article published in “Journal of Human Evolution” describes the exam of some fossils belonging to the genus Homo which may be associated with early stone tools dated at around 2.18 million years ago. Those are a finger bone and of a molar found in the Sterkfontein Caves, in South Africa. Their features make their precise attribution difficult but intriguing.

An article published in the journal “Nature Communications” describes the extraordinary study on the eyes of fossilized specimens of Dollocaris ingens, a crustacean that lived about 160 million years ago, in the middle Jurassic. In the deposits of La Voulte, in the southeast of France, fossils were found in which various soft tissues were also well preserved and this allowed to reconstruct their eyes, giving us an idea of ​​how they saw and indirectly of the environment in which they lived.

An article published in the journal “PLOS ONE” describes the analysis of the partial skeleton of a new species of dinosaur found on a beach near Cardiff, Wales. The fossils date back about 200 million years ago, at the beginning of the Jurassic period. This makes them even more interesting because just a few dinosaur fossils from that period were found so far. According to Dr. David Martill from the University of Portsmouth and his colleagues, the dinosaur found belongs to a genus previously unknown and was named Dracoraptor hanigani.

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.
