New dinosaur identified from a fossil discovered two decades ago in Spain!

Scientists have identified a new dinosaur genus after analyzing the jawbone of a fossil discovered two decades ago in the Portel area of ​​Spain’s Castellón province. Scientists say that the styracosternan hadrosaurid dinosaur was six to eight meters long, a herbivorous and closely related to the species found in modern China and Niger.

The study was titled “A New Styracosteron Hadrosauroid (Dinosauria: Ornithischia) from the Early Cretaceous of Portel, Spain.” The fossil that was part of the research was originally discovered at the Mas de Curoles-II (MQ-II) site. The species had many claws, large nostrils, and a massive tail.

A summary of the paper says, “Autopomorphies include: the absence of a bulge along the ventral margin directly at the base of the coronoid process and a deep oval cavity on the medial surface of the adductor fossa of the mandible below the position of the eleventh-twelfth tooth.” presence.” 

According to the study published in the journal PLOS One , this reptile is believed to have lived on the planet during the Barremian stage of the Cretaceous period, somewhere between 130 million and 129 million years ago. Scientists estimate that the dinosaur may have weighed about 3,600 kilograms.

The scientists say that phylogenetic – evolutionary development – ​​analysis has shown that the dinosaur is more closely related to the African taxon Auranosaurus nigeriensis than to its syncretic Iberian taxa Magnumnus soriaensis and Iguanodon galvansis.

Researchers say the recognition of Portelasaurus sosbyanati is an indication that the Iberian Peninsula was once home to a highly diverse group of Styracosteron hadrosauriforms during the early Cretaceous era.

According to Olhar Digital , this is the 25th discovery of dinosaur species in Spain. Hadrosaurids, also known as duck-billed dinosaurs, are known for their flat duck-bills, the presence of their bones in the snout, belonging to the ornithischian family Hadrosauridae.
The same family, which includes ornithopods such as Edmontosaurus and Parasaurolophus, was a group of herbivores.
