Japan, June 6, 2017:  Scientists in Japan have unearthed the record-breaking 72-million-year-old fossil of the largest complete dinosaur skeleton of the island nation in Japan’s northern island of Hokkaido.

The discovered bones belong to a certain specimen of a duck-billed dinosaur. Paleontologists from Hokkaido University and Hobetsu Museum in Mukawa have been indulged in the excavation of the skeleton since 2013.

Other such fossils of the duck-billed dinosaur species, or Hadrosaurus, have been discovered in Eurasia, North America, South America, and Antarctica. According to available information about the species, The herbivores roamed the earth during the Late Cretaceous Period, between 100 million and 66 million years ago.

According to UPI reports, the latest discovery marks just the third time a Hadrosaurid fossil has been recovered from marine deposits. It is notably rare for a complete skeleton to be discovered in marine strata. Any fossil skeleton with more than 50 percent of the specimen’s bones intact is considered to be a complete skeleton.

The exact species of the newly discovered dinosaur is still unknown, but scientists have decided to name the dino as “Mukawaryu,” Japanese for Mukawa dragon.

In a news release, lead researcher Yoshitsugu Kobayashi said,  “We first discovered a part of the fossilized Mukawaryu skeleton in 2013, and after a series of excavations, we believe we have cleaned more than half of the bones the dinosaur had, making it clear that it is a complete skeleton.”

The main Hadrosaurid family tree can be divided into two distinct groups- species with a crest belong to Lambeosaurinae, uncrested species belong to Hadrosaurinae.

Kobayashi also stated that although Mukawaryu bears some characteristics of both groups, the preliminary analysis indicated it might belong to the Hadrosaurinae. Which group the Mukawaryu skeleton belongs to will surely be cleared by further cleaning of the fossils and detailed research.

The thigh bone of a giant dinosaur was found this week by French paleontologists at an excavation site in southwestern France where remains of some of the largest animals that ever lived on land have been dug up since 2010.

The two-meter long femur at the Angeac-Charente site is thought to have belonged to a sauropod, herbivorous dinosaurs with long necks and tails which were widespread in the late Jurassic era, over 140 million years ago. “This is a major discovery,” Ronan Allain, a paleontologist at the National History Museum of Paris told Reuters. “I was especially amazed by the state of preservation of that femur.”

“These are animals that probably weighed 40 to 50 tons,” he said. Allain said scientists at the site near the city of Cognac have found more than 7,500 fossils of more than 40 different species since 2010, making it one of the largest such finds in Europe. (VOA)
