10 interesting discoveries of dinosaurs in 2020


Dinosaurs became extinct about 66 million years ago; But the secrets of many of them are still intact. This article is about 10 amazing dinosaur discoveries; From newly discovered species to the analysis of eggs and even the removal of some species.

1. Spinosaurus can swim

Scientists have thought for years that Spinosaurus was a swimmer. To prove this claim, they had no evidence other than a few exquisite fossils. It is worth mentioning that the most complete example of them was destroyed in the Allied bombing of Germany in World War II. Analysis of the spinosaurus’ tail now reveals that the dinosaur’s broad tail acts like a paddle for a swimmer. The findings were published in the April issue of the journal Nature. Nizar Ibrahim“This cuneiform discovery on the coffin of the idea that non-flying dinosaurs never invaded aquatic territory,” said the study’s lead author and archaeologist, University of Detroit Miris, archaeologist, said in a statement. This dinosaur (Spinosaurus) was actively looking for prey in deep water, not standing in shallow water waiting for fish.

۲. The best preserved dinosaur stomach

It is difficult to know exactly what herbivorous dinosaurs ate. The leaves and other plant materials do not take on a good fossil state; Even if the ancient organic matter is well preserved, it is safe to know that the dinosaur ate it. These materials may have been fossilized together by accident.

Discovery of fossils نودوسورید With a well-preserved digestive tract, it helps to unravel the mysteries of nutrition. Researchers analyzed the fossilized contents of the 112-year-old animal and found a dinosaur. The fossilized nodosoride called Borealopelta Markmitchelli was a fern. The study was published in the June issue of the Royal Society Open Science.

Markmitchelli was 18 feet (5.5 m) tall and ate only certain types of ferns, apparently preferring leaves to stems and branches. Also, this dinosaur had large stones between peas and grapes called gastroliths, with which it probably digested food.

3. Unicorn titan embryo

Were the big-necked dinosaurs dinosaurs before they grew up? A study published in the journal Current Biology in August found that the discovery of a rare Titanosaurus dinosaur embryo in Argentina showed that these insidious little children had rhino-like horns on their snouts that they lost by adulthood. It is not yet known whether the gigantic parents of this small dinosaur 80 million years ago really thought it was a beautiful horn. Of course, the child may use it to get out of its shell.

4. Eggs with soft shell

A study published in the June issue of the journal Nature found the discovery of the first dinosaur eggs that may have soft shells. Researchers have discovered the ancient eggs of two species of dinosaurs: Protoceratops unicorn dinosaurs that lived during the Cretaceous; ۲. The Sauropodomorph dinosaur, the long-necked Musurus, lived during the Triassic.

In a separate study in the journal Nature, another group of scientists in Antarctica found a 68-million-year-old soft-shelled egg from Musosa, which is not actually a dinosaur; Rather, it is a creeping sea monster that lived in the time of the dinosaurs. It is still a mystery to researchers that this muscovite egg, the size of a soccer ball, was placed in water or on a dry ground like a turtle.

5. Meet T.Rex Cousin: “Death Reaper”

Tyrannosaurus has found a new cousin with a scary name: “Death Reaper”. This is a dinosaur currently found in Alberta, Canada. The 79.5-million-year-old is the oldest recorded tyrannosaurus in North America. It is also the first time in 50 years that a new tyrannosaurus dinosaur has been discovered and recorded in Canada.

“This dinosaur was definitely a very large animal, about 8 feet (2.4 meters) tall,” Jardworis, a doctoral student at the University of Calgary in Alberta and lead researcher on the study, told LiveScience. The “Death Reaper” had unique vertical protrusions that extended from the eyes along the upper snout. Scientists still do not know why a carnivorous animal should have these bumps.

6. That was not a dinosaur

A 99-million-year-old piece of amber from Myanmar (formerly Burma) made headlines with mysterious skulls that are well preserved inside. Researchers believe this is the smallest dinosaur ever discovered. This bird-like dinosaur has about 100 sharp teeth and weighs only 0.07 ounces (2 grams); About the weight of two dollar bills!

Analyzing more specimens of the animal, scientists say it is not a dinosaur; It is a lizard; As a result, the original study was withdrawn. Even if the original research fails, researchers are very excited about this bizarre discovery. The study’s lead author, Jingmai O’Connor, was previously a senior professor of vertebrate paleontology at the Academy of Chinese Sciences. Currently, the Academy of Chinese Sciences is the Chicago Field Museum of Natural History.

7. Tyrannosaurus embryos

At present, only two tyrannosaurus embryos have been discovered and are very small. The predator first began evolving into a mouse-sized skull. Fossils of these infants include the toes discovered in Alberta and the jawbone found in Montana. Gregory Fonston“These findings are extremely rare and the first of their kind in the world,” a senior researcher at the University of Edinburgh in Scotland told LiveScience in October. “Juvenile tyrannosaurs of any kind are rare, and so far we have not found a bone that we suspect may be an embryo.”

8. Two theories about Nanotyrannus

Is there a species of Nanotyrannus? Researchers say some of the remnants of the tyrannosaurus belong to the pygmy tyrannosaurus called Nanotyrannus; While some of them are remnants of a type of Tyrannosaurus rexs. Most researchers believe that the existence of Nanotyrannus is not completely ruled out; Therefore, until more evidence is gathered, there is a possibility that this animal is real.

In 2020, two studies were conducted on Nanotyrannus and unfortunately it was said that this Rex is a teenager:

  • The January study, published in the journal Science Advance, looked at two well-known specimens of Tyrannosaurus, nicknamed Jane and Pitti. Bone analysis revealed that Jane and Pitty were only 13 and 15 years old and that their bones were growing rapidly; Just like a teenager.
  • In a June study published in the journal PeerJ, 44 different species of turkeys were examined and the growth stages of the species were analyzed. Adolescent turkeys fit perfectly into growth curves. This indicates that Nanotyrannus is a species, not a separate species.

9. Dueling dinosaurs were sold to the museum

Finally, scientists are studying two famous dinosaur fossils. These so-called “dueling dinosaurs” are the most complete fossils of Tyrannosaurus rex and Triceratops ever discovered. Scientists believe that the two dinosaurs may have been in a duel at the time of their death. Two dinosaur fossils make their way to the North Carolina Museum of Natural Sciences for $ 6 million.

In 2006, amateur fossil hunters in Montana discovered dueling dinosaurs; But they could not sell them. They even managed to sell them in 2013, and eventually the landowners where the fossils were discovered claimed they existed. After all, the 67-million-year-old duel dinosaurs are now on display in an extraordinary exhibition for the public and students, and scientists are studying them.

A newly discovered dinosaur named Ajnabia odysseus was found where it should not be. A November study shows that dinosaur fossils were discovered in Morocco. Nicholas Longrich“This is completely out of place,” said a senior researcher at Bot University. “Like finding a kangaroo in Scotland!” Newark developed in North America and later spread to South America, Asia, and Europe. Not to mention that Africa was an island continent 66 million years ago, in the late Cretaceous, when A. odysseus was alive. How did he get there?
