A torrential rain hit the Patagonia Plateau in South America 90 million years ago, and the heat that lasted for a long time disappeared. The half-bird Lavigne was running in the heavy rain, and the rain came too quickly, leaving it unprepared.
Half a bird
Awell hurriedly ran in the direction of home, it was hatching to half of the eggs and covered with thin leaves, such a heavy rain did not know whether it would wash the eggs away, it was worried in its heart. Avril Lavigne, who ran up, was like a bird flying in the sky, light and fast. The long, colorful feathers on its forelimbs stretched out in the wind and rain to meet the huge raindrops. They flapped up and down, allowing Lavigne in the wind and rain to move forward steadily in the rush.
The Lavigne family did not originally live on this land, and long ago, their ancestors migrated from the far north to South America, and the Lavigne family took root here. It raised so many children on the land, including the five guys who were still in the eggshells. Lavigne's entire body was drenched by the heavy rain, and the original beautiful feathers clung tightly to her slender body, which was 3 meters long, but only weighed 70 kg.
Behind a silver fir tree, an armadillo crocodile did not hide from the heavy rain as Avril, and the thick scales on its back made it care about the bean-sized raindrops. The armadillo crocodile is intently digging next to a shrub, and even when it rains, it has not forgotten its hobby, because it always gives it a windfall. However, today's work does not seem to be going well. The armadillo crocodile has been digging for half a day, but it has not seen a single food. The armadillo crocodile stopped, and it looked around, hesitating whether to avoid the rain for a while or dig somewhere else.
While the armadillo crocodile was hesitating, a shower of rain washed across the land on the other side of the bush. The dark green leaves on the ground were washed away by the rain, leaving behind five bare eggs. The armadillo crocodile was excited, it originally thought it was just some fallen leaves, but it did not expect that it was a mother who secretly covered it to protect her children. The armadillo crocodile crawled toward the eggs, its mouth full of saliva. It seems that if you continue to work hard when everyone else is lazy, there will always be a windfall, the armadillo crocodile thinks.
Dinosaur eggs
Avril hurried through the silver fir forest. Through this forest, it will be able to find its children. As it walked in the morning, it hid them under a bush. It remembered the shrub, and many of its children were hatched under it. The rain was getting more and more urgent, and Avril's heart was getting more and more anxious, and it quickened its pace.
Coming out of the silver fir forest, turn a corner to the left, about 500m, where Avril buried the egg, and it will soon arrive. However, at this moment, Avril saw the armadillo crocodile, the large and bulky brown monster crawling slowly toward its egg.
Bird Dragon
"Oh my God!" Avril screamed in her heart, almost as if she were flying, and a jump slid down the sky. Before the armadillo crocodile touches its egg, it stands firmly in front of the egg. The armadillo crocodile lying on the ground was obviously frightened by the sudden arrival of the big monster in front of him, and how to suddenly have another guy to grab food with it. The armadillo crocodile stopped, shook its body in anger, and prepared to start a battle. Of course, Avril did not show weakness, and it slapped its feathered forelimbs up and down, throwing the rain everywhere. Not satisfied, it showed the sickle-like claws on its feet to the armadillo crocodile, staring at the armadillo crocodile fiercely.
The armadillo crocodile hesitated a little, and it felt that the guy in front of him who had come to grab food with it didn't seem to be easy to deal with. It was thinking about what to do. The two sides were deadlocked in the rain, and the air was filled with pre-battle tension. Rubbing the ground, Avril took advantage of the fact that the armadillo crocodile was not paying attention, and suddenly jumped from the front of the egg to the back of the egg. The armadillo crocodile did not expect Avril to have such a movement, it did not know what action Avril was going to take. The armadillo crocodile does not dare to act rashly, and can only vigilantly observe the enemy situation.
However, Avril did not seem to have any intention of attacking. It scratched some of the leaves beside it, and then used them to cover the egg again, and its eyes were full of pity. It wants to use leaves to protect the eggs first, and it also wants to use leaves to shield its children from the rain.
The armadillo crocodile noticed Avril's move, and it realized that the other party was not here to fight for food but to protect its children. The armadillo crocodile's mind was constantly guessing the identity of the enemy, but after Avril covered the children with leaves, she took advantage of the armadillo crocodile's inattention and, with lightning speed, spread her arms and jumped on the back of the armadillo crocodile. Avril unleashed its terrible sickle-like claws and stabbed fiercely into the armadillo crocodile's abdomen, which was not protected by scales.
The armadillo crocodile screamed and reacted from the crank. Although Avril did not have much advantage over her body, this sudden attack still made it hurt to the bone. It shook its body desperately, knocking Avril off her body, then turning her head and quickly fleeing in the direction it had come. It didn't want to continue in this battle, because it was wounded, and because it met a mother, it could imagine what kind of bloody battle would be in the coming battle, and it didn't have to lose its life for those few eggs that didn't know the taste. Avril didn't chase after it, and it couldn't leave her eggs in pursuit of the enemy. Moreover, if you catch up, you may not be able to win the armadillo crocodile.
The rain in the sky gradually subsided, and the sun smiled again. Avril stood next to the children, watching warily. The sunlight quickly dried its feathers and re-emitted its shiny colors. Such battles in the jungle are experienced many times a day, and the rain is gone, but Aizor must be vigilant for the next danger.
To this day, in the study of dinosaurs, the Avril family still occupies a considerable weight. Because the half-bird represents a special type of chiron in the southern continent of Gondwana.

In the early 1990s, the Argentine paleontologist Onilas. Novas found more than 20 fossils of half-birds on an ancient riverbed on the Comayo Peninsula. The research paper was published in the May 22, 1997 issue of the journal Nature Issues. Onillas. Novas described the animal as "an animal with half bird features from northwestern Patagonia". The fossils of the half-bird found are currently preserved in the Buenos Aires Museum of Natural History.
Half-bird, also known as Wakatori, is a scientific term derived from Latin and the language of the local Mapuche Indians, meaning "half a bird". The model species of half-bird is named The Comayo Half-Bird, and the species name comes from the Comayo Peninsula where fossils of the half-bird were found. The second species of the genus, the Pascher's half-bird, was named and described in 2004. The half-bird lived in the Patagonian region of Argentina in late Cretaceous South America 90 million years ago and belonged to the famous Chilong family.
Dinosaur fossils
The hemibird is 3 m long, 1.2 m tall, weighs about 70 kg, and is medium-sized. The half-bird is athletic, agile, and an efficient predator. Its special shoulder strap structure has attracted the attention of paleontologists: the forelimbs of the half-bird are located on both sides of the body cavity, and can not only do the movement in the front and back directions, but also in the vertical direction, that is, flapping up and down like the wings of birds. Although the size of the half-bird proves to be unfit for flight, it is able to wield its forelimbs like bird wings as a weapon.
Another view is that the half-bird has long feathers on its forelimbs, a structure that helps keep the body balanced and steered as the animal runs at high speeds. The structure of the shoulders and forelimbs of the half-bird provides fossil evidence for our study of the origin of the birds' flight, and Novas noted in his study that the pelvic part of the half-bird was very similar to that of the early bird Archaeopteryx.
Archaeopteryx
The half-bird is a very bird-like dinosaur that represents a special type of chicosaurus in the southern continent of Gondwana. Paleontologists established the subfamily Hemiosaurus from it as a model genus, under the Chironidae family. The subfamily Half-Bird family includes Vultures and Neuquénosaurus, which are native to South America.
In 2005, Peter. Markvich and others proposed that the flying ability of the birds belonged to the subfamily of the half-bird, and if this idea is true, then the chirons and others produced in South America, such as the half-birds, are likely to have evolved from the early ancestors who had the ability to fly like the birds. If this assumption holds, then the name of the half-bird is worthy of the name. Due to the incompleteness of the half-bird fossils, some paleontologists once thought that the half-bird was nothing more than a juvenile grand theftosaur, but recent discoveries from Australia have proved that the great robber belongs to the neo-dipterosaur family under the allosaur superfamily, so this view is self-defeating.
