Tiny Dinosaur Relative Roamed Triassic Madagascar. Insect-hunting dinosaur “the size of a teacup” unearthed in Madagascar. Tiny Dinosaur Related Roamed triassic Madagascar. A new genus and species of ornithodiran, an early relative of dinosaurs and pterosaurs. Which lived about 237 million years ago (Triassic period), has been identified from fossil remains found in southwest Madagaskar.
Famous by the name of Kongonafon. The ancient reptile was surprisingly small (approximate height: 10 cm, or 3.9 inches). Its small body size can help explain the origin of the flight in the pterosaur and the presence of uzz fudge ‘on the skin of both the pterosaur and the dinosaurs. The restoration of Kongonphon’s life. There is a general perception of dinosaurs as giants.
But this new animal is very close to the divergence of dinosaurs and pterosaurs, and it’s surprisingly small, said Dr. Christian Kammer. A curator of research in paleontology at the North Carolina Museum of Natural Sciences. The discovery of this small (Tiny) relative of dinosaurs and pterosaurs emphasizes the importance of the Madagascar fossil record in improving knowledge of the history of certebrates.
Which is poorly located elsewhere, said Professor Lovasoa Ranvihaarimana from Antonanivavo. A partial Kongonaphone Kelly skeleton was found in 1998 in the Morondwa basin of southwestern Madagascar. The restoration of Kongonphon’s life. Dr. Kammer said: Kongonfon is not the first known small animal near the root of the olithodiran family tree, but previously such specimens were considered isolated exceptions.
tiny epic dinosaurs
In general, the scientific idea was that body size was similar among previous dinosaurs, the largest group of reptiles including birds, crocodiles, non-avian dinosaurs and pterosaurs, and the oldest ornamodirones, in large proportions in the lineage. of the dinosaurs. Before getting up. Recent Kongonphon discoveries have given us a better understanding of the early evolution of ornithodirans (tiny epic dinosaurs).
Analyzing the changes in body shape in the evolution of entire dinosaurs. We have found that it has declined early in the history of the dinosaur-Potosaur lineage. This miniaturization phenomenon indicates that dinosaur and pterosaur lineages originated from extremely small ancestors and producing significant implications for their biology. The microwar placed on Kongonphon’s conical teeth indicates a diet of hard worms.
small-bodied common ancestor
For insectivores, this change, associated with a smaller body size, may have helped early ornithodirans survive by occupying a different space than most of their contemporary meat-eating relatives. The study also suggests that fuzzy fur coatings ranging from simple filaments to feathers, known on both the dinosaur and pterosaur sides of the ornithodirane tree, may emerge for thermoregulation in this small-bodied common ancestor.
Because heat retention in small bodies is difficult, and the late Triassic climate was an extreme time, anticipating a sharp change in temperature between hot days and cold nights. This discovery is stated in a document in the Proceedings of the National Academy of Sciences.
Small four-inch-long dinosaurs
Small four-inch-long dinosaurs that roamed Madagascar more than 240 inches ago suggest that T-rex and other giant reptiles evolved from miniature ancestors. Small extinct insect-fed dinosaur ancestors had sharp claws and hairs. Researchers discovered a miniature lizard, which roamed Madagascar about 240 million years ago, and said it was only four inches (10 cm) long. This tiny creature is believed to be the ancestor of very large dinosaurs and pterosaurs.
Called Kongonfaffen, or ‘Little Bug Killer’, he was smaller than a sparrow and had bugs on his paws and buckets, teeth on his sharp claws for biting. It dates back to Madagascar and is a “missing link” in vertebrate history, that is, from the team at the North Carolina Museum of Natural Science. Kongonphon’s remains were discovered in 1998, but were found along with many other fossils that have long taken scientists to understand their importance.
Restoration of the life of Kongonfon

A paleontologist at the North Carolina Museum of Natural Sciences, lead author Dr. Christian Kammar said that people believe that dinosaurs were all giants.
“But this new animal is very close to the divergence of dinosaurs and pterosaurs, and it’s very small,” he said. Some dinosaurs were over 100 feet long and weighed over 100 tons, and their closest aerial cousin. The Potrosaurus, were the largest animals to have ever flown. Some were shaped like a modern airplane, with a wingspan of up to 35 feet (10 m).
National Academy of Sciences
Both ancient reptile groups belong to the Ornithodira group, but their origins remain a mystery to the very few fossils of their previous relatives. Until Kongonfon was discovered in an archaeological dig. The lizard was the lizard that shared key characteristics with its older cousins.
The study, published in the Proceedings of the National Academy of Sciences, has implications for the development of birds which are living descendants of dinosaurs. The North Carolina team said it could help explain the origin of the feathers and why pterosaurs went to heaven in the first place.
The findings highlight the presence of ‘fudge’ on the skin of the Lizard species. Professor John Flynn, expedition leader at the American Museum of Natural History in New York, notes that the site where the fossil was unearthed in southwestern Madagascar comes from globally poor time intervals.
modern technology to analyze recovered fossils
This little specimen, Flynn said, was collected from the site we had collected for hundreds of years. `We needed some time before focusing on these bones, but once we did, it became clear that we had something unique and that it was worth looking closely. It is a great case that field discoveries, combined with modern technology to analyze recovered fossils, remain so important.
Notably preserved specimens included parts of Cogonphon’s skull and limbs capable of accurately reconstructing their appearance. They were around 237 million years old, when the exotic African island was part of the Pangea supercontinent and the first dinosaurs emerged.
Restoration of the life of Kongonfon, a recently described reptile close to the lineage of dinosaurs and pterosaurs, widely demonstrated by human hands. The Kongonfon Restoration of Life, a newly described reptile close to the lineage of dinosaurs and pterosaurs, has been shown to be widespread by human hands.
newly discovered congonaphone
Comparison of physical size between the newly discovered congonaphone and one of the first dinosaurs, Herrasorus “Recent discoveries like Kongonafon” have given us a better understanding of ornithodirane’s early development, he said. By looking at changes in body size over the course of biological size evolution.
We found compelling evidence that this decreased early in the history of the dinosaur-Pterosaur lineage. The study found that giant dinosaurs, which became extinct about 66 million years ago, originated from extremely small ancestors. The fossil also obtained more information on the life of the specimen.
The researchers believe that the wear marks on his teeth are evidence that he ate the insects. A change in an insectivorous lifestyle, associated with small body size, may have helped early ornithodirans survive, along with changing the world and requiring them to find a new niche.
They occupied a different place for their fellow carnivores, which means they would not be rivals, the team explained and the fuzzy fur coatings, from simple fibers to feathers, which were common in dinosaurs and pterosaurs, could start at Kongonfon for thermoregulation. Small-body heat retention is difficult, and the late Triassic temperature was an extreme time, with a sharp change between warm days and cold nights.
Lovaso Ranoviramanana, co-leader of the project, vertebrate specialist at the University of Antananarivo in Madrasaskar. This was a very important discovery. The discovery of this small relative of dinosaurs and pterosaurs emphasizes the importance of the Madagascar fossil record. Which is little known elsewhere over time to improve knowledge of Kabirpanthi’s history.
About 251 million years ago, at the end of the Permian period, a mass extinction wiped out most of life on Earth. In light of this. The arrival of a group of egg-laying reptiles were called Arcosaurus, the common ancestor of dinosaurs, flying reptiles called pterosaurs, and crocodiles. At some point during the next period, the Tricic, Pterosaurus, and Dinosaurs broke away from the crocodile lineage. Kongonphon Ara has another piece.
The eggshells suggest that the dinosaurs were really warm blooded. New Yale research has sparked controversy over whether the dinosaurs were hot-blooded or cold-blooded. The chemistry of dinosaur eggs has been analyzed in new research. A new fossil egg has analyzed the debate over whether dinosaurs were cold-blooded like modern reptiles or modern warm-blooded birds.
The chemistry of dinosaur eggs
New research by Yale scientists in the US has looked at dinosaur egg shells in the way the oxygen and carbon atoms within them were organized and suggesting that they formed inside bodies with hot blood. Dr. Robin Dawson stated that dinosaurs sit at an evolutionary point between birds, which are warm-blooded and reptiles.
Which are cold-blooded. A cross section of a testicle shows mineral development. Pic: Robin Dawson. Our results suggest that all major dinosaur groups had warmer body temperatures than their environments, Drs. Dawson said about the research, while she was a doctoral student in geology and geophysics at Yale.
The research follows a new theory that suggests that dinosaurs evolved into birds that shrunk to become warm-blooded. Reptiles are cold blooded or ectothermic, which means they cannot control their body temperature. Mammals and birds. Which come directly from a group of dinosaurs called theropods, are warm-blooded or endothermic.

Which means they produce their body temperatures. Generating your own heat is an expensive lifestyle for animals and requires very high energy consumption. However, it offers benefits in that it allows animals to function at higher levels when there are no external heat sources nearby, such as at night or winter.
The fossilized bones of a giant theropod dinosaur, Gigantoratrapt irelensis, are shown to the media in Beijing on June 13, 2007. The remains of giant dinosaurs, strikingly bird-like, were revealed in Inner Mongolia, China. The animal, which lived in the Late Cretaceous period (about 70 million years ago), is believed to have a body of approximately 1,400 kg.
Journal Science Advances
Which is surprising because most theories suggest that carnivorous dinosaurs got smaller. Theropod dinosaurs are the bird’s most direct ancestor. Dr. Dawson is the lead author of the new study in the Journal Science Advances that tested egg fossils from three major groups of dinosaurs. Using a technique called subject isotope paleothermometry, the researchers discovered what the dinosaurs’ internal temperatures were as the eggs formed inside them.
Species shells, including carnivorous theropod trodone, duck-billed myasaura and megalith, were grown at temperatures well above their environment. “We found that this indicates that the ability to metabolize their temperature above the environment was an early and evolving trait for dinosaurs,” said Dr. Said Dawson. Myasaura is a large duck-billed dinosaur that lived in the Cretaceous Era in North America with various hatches shown here.
Development of feathers
The large duck-billed dinosaur has increased 44 degrees Celsius (111.2 degrees Fahrenheit) since Myashore. Myasaura was a large duckling dinosaur that lived in North America. One of the implications of the study refers to the development of feathers in relation to their development in birds. “It is possible that dense feathers were chosen primarily for isolation, as body size decreased in theropod dinosaurs in the path of development of modern birds,” said Dr. Dawson.
Dinosaurs Was Warm-Blooded, Using A Novel Technique Called Fossil Eggshells Suggests Study. The Paleothermometry Of Clustered Isotopes. An international team of Paleothermometry analyzed the egg fossils that represent the three main groups of dinosaurs and discovered that these creatures were characterized by warmer body temperatures. A dinosaur similar to a cassowary called Bbilong sinensis in egg incubation.
Major groups of dinosaurs
Researcher at the Department of Geology and Geophysics at Yale University, Dr. Robin Dawson said: “Dinosaurs sit at an evolutionary point between birds, which are warm-blooded and reptiles, which are cold-blooded. Our results suggest that all major groups of dinosaurs had warmer body temperatures than their environments. Dr. Dawson and his colleagues applied their novel method to the testicles of three main groups of dinosaurs: Ornithisia, Soropodomorpha and Theropoda.
He explained: “The paleothermometry of closed isotopes is based on the fact that the order of the atoms of oxygen and carbon in the shells of fossilized eggs is determined by temperature.” Once you know the order of those atoms, you can calculate the internal temperature of the mother dinosaur’s body. For example, the eggshells of a trodone, a small sludge for eating meat, were tested at 38 °, 27 ° and 28 ° C (or 100.4, 80.6 and 82.4 ° F).
Egg shells from Alberta
The large Myasora duck-billed dinosaur egg shell produces a temperature of 44 ° C (111.2 ° F). The eggshells of Trudon and Myasora were from Alberta, Canada. Meanwhile, fossilized dinosaur egg fossils were tested at 36 ° C (96.8 ° F) in a classification of a species restricted to Romania’s dinosaur egg megalith.

The scientists performed the same analysis on cold-blooded invertebrate shells similar to the shells of dinosaur eggs. This helped the team determine the temperature of the local environment and whether the dinosaur had a higher or lower body temperature.
“Troodon samples were 10 ° C (50 ° F) warmer than their atmosphere, Myasaura samples were 15 ° C warmer (59 ° F) and Megalithius samples were 3-6 ° C (37.4-42.8 °).) They were. Fahrenheit) hot, “said Dr. Dawson. What we found suggests that the ability to metabolize its temperature above the environment was an early and evolving feature for dinosaurs. The results have been published in the Journal Science Advances.

The 40-foot-long hunter who crushed bones inside a five-foot-long head is a legend. Now, a look at two medium-sized bones, the immature T. Rex also informs scientists about the terrible teenagers of the dictator King. In the early 2000s, two relatively small T-shirts from Carter County, Montana, of the Burpee Natural History Museum in Rockford, Illinois. Rex fossil skeletons were collected.
The nicknames “Jane” and “Patty” would have been a little longer and double that of the tortured draft horse. The team led by Holly Woodward, PhD, of the Oklahoma State University Health Sciences Center, T. Studied Jane and Pete to better understand the history of Rex’s life. The study “Growing Tyrannosaurus T-Rex.
Histology refutes the pygmy ‘nanotaraneus’ and supports the division of the oncogenetic niche into the juvenile Tyrannosaurus” appears in the peer-reviewed journal Journal Advance. Co-authors include Jack Horner, a member of the president of Chapman University; Nathan Myhrold, founder and CEO of Intellectual Ventures; Katie Tremaine, a graduate student at Montana State University.

The complementary histological work was carried out in the Diane Gabriel Histology Laboratories at the Rocky Mountain Museum / Montana State University.
Historically, many museums would collect fossils of larger and more influential dinosaur species to display and ignore others, said Woodward. The problem is that these small fossils can come from small animals. Therefore, there are large gaps in our understanding of how dinosaurs grew, and T. rex is no exception. The small size of Jane and Patty makes them incredibly important.
Now scientists can not only study that T. How bones and proportions changed as Rex, but they can also use paleontology, the study of fossil bone microstructures, to learn about youth growth rates and age. Woodward and his team pulled thin slices of the bones from Jane and Patty’s legs and examined them with great magnification.
Fossil dinosaur bone
It’s always surprising to me that if you have something like a giant fossil dinosaur bone. It’s also a fossil at the microscopic level, said Woodward and by comparing these fossil microorganisms with similar characteristics found in modern bones, we know they provide clues about metabolism, growth rates and age.
The team determined that the youngest T. Los Rexes were growing as fast as today’s warm-blooded animals, such as mammals and birds. Woodward and his colleagues also discovered that counting annual rings inside the bone and as well as counting tree rings, had led T-Rex to be youthful when Jane and Patty had died; 13 and 15 years old respectively.
T-Rex was not a new species of dragon
It was speculated that the two smaller skeletons were not T-Rex, but a relative nanotairene of a small pygmy. Bone studies with histology led researchers to conclude that juvenile skeletal T-Rex was not a new species of dragon. Instead, Woodward points out, as T. to reach adult size. It had taken Rex twenty years.
The tyrannical king may suffer mature changes. Teens like Jane and Patty were sharp, with floating legs and knife teeth to bite, while adults were crushing bones. Not only that, but Woodward’s team discovers that T.W. Growing Rex can be a good trick. If your food source was scarce for a particular year, it didn’t grow as much and if the food was plentiful, it increased a lot.
The world’s most famous dinosaurs
The space between annual growth rings records how much a person grows from one year to the next. The space between rings between Jane, Pete and even older people is inconsistent, the space with a few years. It is close, and in other years it has spread. Besides, “said Woodward.
The research conducted by Woodward and his team has written a new chapter in the early years of the world’s most famous dinosaurs, providing evidence that he assumed the crown of the dictator king long before reaching adult size.
The researchers found Teen-age T-rex, find out more about T-Rex: Without a doubt, Tyrannosaurus rex is the most famous dinosaur in the world. The 40-foot-long hunter who crushed bones inside a five-foot-long head is similar to the legend. Now, a look at the two medium bones, the immature T. Rex also allows scientists to learn about the dictator King’s terrible teenager.
