The New Fossil Is The First Fossil Biggest Egg Found In Antarctica

Antarctica’s ‘deflated football’ fossil is world’s biggest egg. The new fossil is the first fossil egg found in Antarctica. Paleontologists explore the giant cold-shelled eggs of marine reptiles from the Cretaceous period in Antarctica. In Antarctica, a huge fossil egg of extinct marine reptiles has been found in nearby marine deposits 68 million years old. An artist made a couple of mosques and their eggs. Under the name of Antarcticulithus Brady.

The new fossil is the first fossil egg found in Antarctica. The sample exceeds all known non-avian dinosaur eggs in quantity and differs from them in composition. Measuring 11.4 by 7.9 inches (29 cm by 20 cm) and weighing 6.5 kg, it is the largest soft shell egg ever discovered and the second largest egg of any known animal. Although the elephant bird’s egg is slightly larger, its egg is about five times as thick.

University of Texas paleontologist Austin Legend Lucas and colleagues from the United States and Chile think that Antarcticulithus brady was placed by a giant marine reptile, such as a mosasaur, a discovery that challenges the prevailing belief that such organisms thought that such creatures did not lay eggs. The fossil egg is a dinosaur with a shape larger than an animal.

It is completely different from a dinosaur egg. It’s similar to the eggs of lizards and snakes, but it’s from a really huge relative of these animals, said Dr. Legend said. A diagram showing the Antarcticulithus Brady egg, its portion and shape relative to an adult human. The researchers found several layers of membranes, confirming that Antarcticulithus bradii was an egg.

The structure is very transparent, rapid hatching, similar to the eggs laid by some snakes and lizards, said Dr. Legendre. However, because fossilized eggs hatch and do not contain skeletal material, the scientists used other types of reptiles to focus on them. Artist’s rendering of a baby mossaurus growing from an egg. They created a data set to compare the body size of 259 living reptiles with the size of their eggs.

They discovered that the snake that laid the egg was 7 meters (23 feet) long from the end of its body to the end of its body, not counting the tail. In addition to that evidence, the rock formation where the Antarcticulithius Brady egg was discovered houses adult specimens, as well as the skeletons of baby Mosauer and Plesiosaurus. Many authors hypothesized that it was like a nursery with protected shallow water.

A cove environment where young people would have a peaceful environment to grow, said Dr. Legend said. The study was published in the Journal Nature. Paleontologists explore the giant cold-shelled eggs of marine reptiles from the Cretaceous period in Antarctica. Dinosaurs and soft shell eggs from Antarctica. This is a great day for great egg stories, as if both the egg and the story are great.

In separate articles in the journal Nature, a team of scientists reports that it is the second largest egg of any known animal, and another suggests that, contrary to established thinking, the earliest dinosaurs made soft-shell shells.

Dinosaur Eggs

In the first article, the egg is also soft spherical, and at a distance of about 28 centimeters to 18 centimeters it pushes how great scientists thought such eggs could develop. It is the first fossil egg to be found in Antarctica and the authors believe it was laid by an extinct giant marine reptile, such as a magasaurus.

A discovery that defies the prevailing challenge that such creatures did not lay eggs. It is the size of a large dinosaur from an animal. But it is completely different from a dinosaur egg, says author Lucas Legendre of the University of Texas at Austin (UTA), It is similar to the eggs of lizards and snakes, but it is really huge compared to these animals.

David Rubilar-Rogers, co-author of the Chilean National Museum of Natural History, was one of the scientists who discovered the fossil in 2011 and making it look like bad football. By the time Julia Clarke of UTA suggested that neither Chile nor geologists could discover that it really was a bad egg. Studies with a set of microscopes confirmed this and revealed a transparent, fast-hatching egg-like structure that some modern snakes and lizards lay on.

Comparison with data from 259 live reptiles suggested an ancient marine reptile. An idea supported by the number of Baby Mossaur and Plesiosaurs skeletons in the area. Many authors have hypothesized that it was like a nursery with protected shallow water, a cove environment where young people would have had a quiet environment to grow, says Legend.

Fossil egg

The document doesn’t look at how ancient reptiles would have laid eggs. But researchers have suggested two possible options. The eggs are in open water, giving birth to certain types of sea snakes, or the mother lays the eggs on Huh beach. And the hatchling was shattered like sea turtles in the sea. Dinosaur egg: fossil egg, its parts and relative size.

The arrow points to its layers and the surrounding sediment, which is shown in light gray.  In a second study, researchers led by the American Museum of Natural History (AMNH) and Yale University used a set of geochemical methods to analyze the eggs of two largely different non-avian dinosaurs and found that they were similar to turtles…in its microstructure.

hard-shelled eggs

Structure and mechanical properties….This suggests to them that the earliest dinosaurs laid soft-shell eggs and that hard-shelled eggs evolved at least three times independently in the dinosaur family tree. “The idea has always been that the ancient dinosaur egg hardened,” says lead author Mark Norrell of AMNH.

In the past 20 years, we have found dinosaur eggs worldwide, but for the most part they represent just three groups: theropod dinosaurs, including modern birds, duck-billed dinosaurs like advanced hadros, and advanced aerotropes, Dinosaurs long neck. At the same time, we have found thousands of skeletal remains of ceratopsian dinosaurs, but none of their eggs.

Dinosaur eggs

So why were their eggs not preserved? I suppose, and what we proved through this study was that they were soft. A group of fossilized eggs and embryos in samples of protoceratops. Norrell and his colleagues in the US The USA, Argentina and Canada studied well-preserved fossil eggs containing embryos belonging to two dinosaur species: Protoceratops from Mongolia and Mussorus from Argentina.

When they chemically characterized the specimens, they found chemically altered remnants of the protected egg mucous membrane. Which make up the innermost testicular layer of all modern archival testes. When they compared the bi-hybrid molecular signature of dinosaur eggs with data from other animals, including lizards, crocodiles, birds, and turtles, they found that the protocarps and musorus eggs were leathery and soft.

Fossil egg development

They provide direct evidence of the independent development of calcified eggs in non-biosynthetic and soft-natured dinosaurs of Prosokeratops and Musaurus eggs, they write in their article. This finding is related to recent findings of various reproductive traits, such as the color of the egg.

The ancestral nest car, and open nest structures, which are limited to dinosaurs, representing an independent lineage of egg development. Because soft eggshells are more susceptible to water damage and provide protection against mechanical stress, such as parenting. The researchers propose that they were probably buried in wet soil or sand and later similar to some reptiles, La decomposing plant was incubated with heat of the substance.
