Discover the dinosaur mummy with horseshoe-shaped footprints in the United States

Edmontosaurus is a very famous herbivorous dinosaur that once lived with Tyrannosaurus rex. Because archaeologists have discovered many of their fossils, researchers think that humanity has discovered all the secrets of this dinosaur. But recent findings indicate that there is still much that we still don’t know. The mummy named Trachodon of this dinosaur told us more that it was a horseshoe-like dinosaur and different from what researchers had previously speculated.

Mummies are a technique for preserving human corpses invented by the Egyptians. In fact, not only do humans have mummies, even dinosaurs living hundreds of millions of years ago could become mummies.

Trachodon is a mummy at the American Museum of Natural History specially preserved natural fossils of the Edomontosaurus duck-billed dinosaur, found in the Lance Formation near Lusk, Wyoming, United States in 1908.

Tyler Lyson is an American paleontologist, in 1999 when he was still in high school, he accidentally discovered dinosaur fossils in his home land in North Dakota and gradually developed a passion for palaeontology.

In 2004, when Lyson returned home, he suddenly thought about the fossils found on his home land, so he took a closer look at those fossils. Surprisingly for Lyson is that in the fossilized samples still on the site there is soft tissue preserved in fossils – this is very rare for conventional fossil samples.

In the summer of 2006, Lyson teamed up with English paleontologist Phillip Manning to begin excavating the fossilized soft tissue. Soon after, the fossils were unearthed and when the fossils were separated from the ground, it was discovered that the mummified remains of a dinosaur – such mummified fossils are extremely rare and rare. also found very little. And because the mummy was found in North Dakota, the fossil was named “Dakota”.

The discovery of “Dakota” is of great significance. Preserved software tissue provides valuable materials for us to truly understand dinosaurs. Through analysis of fossil samples, it was learned that “Dakota” is 11 meters long and weighs about 3.5 tons and belongs to an adult herbivorous Edmontosaurus.

Edmontosaurus is a genus of hadrosauridae. This genus includes two known species: Edmontosaurus regalis and Edmontosaurus annectens.

To better study the dinosaur mummy, Manning borrowed large CT scans from NASA and Boeing to perform detailed and comprehensive scans of fossil-preserved muscle and tendon parts. The results of CT scans proved that the platypus had a long and thick tail, and this was not noticeable to the naked eye when looking at mummies or from fossilized bones of this species. discovered by humans.

Based on the data obtained from the scan, paleontologists also calculated the running ability of Edmontosaurus dinosaurs, which can reach a maximum speed of 45 km / h. Imagine that with a weight of 3.5 tons, “Dakota” can run at such fast speed, they are no different than a grass-based bus is moving.

The discovery and partial research of “Dakota” drew National Geographic’s attention. The staff members tracked and produced a documentary called “Dino Autopsy”.

The story of “Dakota” has not ended there. Through this precious dinosaur mummy, paleontologists have learned more about the muscular attachment and motility of this platypus. Not long ago, when paleontologists studied the “Dakota” forelegs, they found that the structure of their forelegs was completely different from previous understandings.

Before the discovery of “Dakota”, knowledge of the foreleg entirely from bone fossils. From a fossil standpoint, the front legs of this dinosaur have no big toes, while the second, third and fourth toes have the same length and the fifth is significantly shorter than the other three. Therefore, during recovery, the front leg of this species has three toes connected to form the front leg, this structure is suitable for walking on all fours.

When studying “Dakota”, paleontologists did not find any anomalies in the anterior limbs, because their anterior limbs were all with the sole of the foot facing up. Not long ago, researchers were surprised to find that their forelegs had a giant claw. This claw is actually formed from the nail of the third finger, it contains the second, third and fourth fingers, in which the second finger shows a sharp claw and the shorter fifth finger is on the sole of the foot. and do not touch the ground.

The discovery of this giant claw completely disrupted paleontologists’ previous understanding of the front leg structure of Edmontosaurus for more than 100 years since the first fossil record was discovered.

Their forelegs are hooves, and this structure continues to provide researchers with more information about how dinosaurs move and move. However, until now researchers are still a bit confused because it is unknown whether other dinosaurs have similar structures.
