An article published in the journal “Proceedings of the Royal Society B” describes the study of the most massive titanosaurus discovered so far. Called Patagotitan mayorum, it was about 37 meters long (122 feet), about 6 meters (20 feet) tall and its weight was estimated at 69 tons, which make it the largest animal that ever lived on the mainland. It lived in the late Cretaceous, between 95 and 100 million years ago, in today’s Patagonia, Argentina.

An article published in the journal “Nature” describes the discovery in Kenya of a skull belonging to an infant of a species of ape called Nyanzapithecus Alesi. About 13 million years ago, the specimen died at an estimated age of only 16 months but it’s not possible to determine its gender. The skull is the earliest found so far belonging to an ancestor of hominids and apes.

An article published in the journal “Current Biology” describes the study of the exceptionally preserved fossils of an armored dinosaur that was named Borealopelta markmitchelli. Classified as part of the nodosaurid (Nodosauridae) family, according to researchers at MIT, Newcastle University, University of Bristol and Royal Tyrrell Museum that examined it despite its armor it was being hunted by predators.

An article published in the magazine “Scientific Reports” describes a research on a feathered dinosaur that shows not the usual generic similarities to birds but a remarkable resemblance to the cassowary with a crest on its head and long legs. A team of paleontologists led by Lü Junchang called it Corythoraptor jacobsi and it was a dinosaur belonging to the oviraptorid family that lived in the late Cretaceous, between 100 and 66 million years ago, in today’s southern China.

An article published in the “Journal of Paleontology” describes the discovery of what might have been a top predator at the beginning of the Triassic period, between 252 and 247 million years ago. Named Birgeria americana, this fish was long probably less than 2 meters (about 6′) but after the great extinction of the end of the Permian it was perhaps at the apex of the food chain in its ecosystem.
