The largest study on the growth of the dinosaur population reveals how Mysore lived and died and decades of research on the fossils of the state of Montana, the ‘good mother lizard’ Myasaura pibelsorum, is the most detailed life story of any dinosaur and whose result is a model that can be compared to all other dinosaurs.

According to a recently published research, decades of research on the state fossil of the “good mother lizard” Myasaura pibalsaurum has learned the most detailed history of the life of any dinosaur and has created a model that compares with others. It can be done with dinosaurs. Paleobiology Magazine. Researchers at Oklahoma State University,
Montana State University and Indiana Purdue University used a giant fossil collected from bones in western Montana for their study. It is one of the most important paleontology pieces associated with MSU in the last 20 years, said Jack Horner, curator of MS Horn at the Rockies Museum.
This is a dramatic step beyond the study of fossil organisms that understand their life cycle as individuals. We are moving away from the novelty of a single example to the way we see animal populations today. Look at the dinosaur population.
The study was led by Holly Woodward, who conducted a research at MSU as a doctoral thesis in paleontology. Woodward is now an anatomy professor at the Center for Health Sciences at Oklahoma State University. Paleobiology studies examined the microstructure or histology of the fossil bone of 50 tibiae of Mysoreura (calf bones).
Bone histology reveals aspects of development that cannot be achieved simply by observing bone size, including growth rate, metabolism, age of death, sexual maturity, skeletal maturity and access to the size of a species. It contains information.
Woodology is the key to understanding the dynamics of the development of extinct animals, “said Woodward.” You can learn a lot from a bone just by looking at its shape. But the whole evolutionary history of the animal has been recorded within the bone.
A sample of 50 may not seem like much, but for dinosaur paleontologists who often deal with the fossil fossil record, the Mayasaura fossil is a treasure. Woodward stated that no other histological study of individual dinosaur species reached the size of our sample.
Holly Woodward points to the Mysore fossil. Decades of research on the fossils of the state of Montana, the ‘good mother lizard’ Myasaura pibelsorum, have resulted in the most detailed life story of any dinosaur’s life.
Created a model that can be compared to all other dinosaurs. According to new research published today. The journal Paleontology was studied by Woodward, who conducted a research at MSU as a doctoral thesis in paleontology. Sincerely: Karen Chin
The researchers discovered a great deal of new information about the evolution of mysaura: it had a growth rate at the level of the birds throughout its life and was very close to the bone tissue, such as large modern warm and warm mammals.
The main events of life are recorded in bone growth and mortality of animals of different age groups. When studying clues in bone histology and observing patterns in death assemblies, we performed several tests that support the same moment of sexual and skeletal maturation.
Elizabeth Freedman Fowler, Paleontology at the Museum of Dinosaurs of the Great Plains The curator said Professor Malta and the MSU assistant, who did mathematical analysis for the study.
Sexual maturity occurred within the third year of life, and Myasaura reached an average adult mass of 2.3 tons in eight years. Life was particularly difficult for young and old. The average mortality rate was 89.9 percent for those under one year and 44.4 percent for those over 8 years.
If myasaura individuals can survive until their second year, they will enjoy a six-year window of extreme physical and reproductive fitness, when the average mortality rate was only 12.7 percent.
Woodward said: The discovery inside the bones, and previous studies have shown that we now know more about the history of Mysaura’s life and the size of the sample than any other dinosaur. Our study transforms the myasora into a model organism.

Our study transforms the myasora into a model organism, with which other dinosaur populations will be compared with the study of biology.
The tibia 50 also highlighted several size variations within dinosaur species. Previous studies of dinosaurs histologically examined a small subset of dinosaur bones and aged the entire specimen based on the length of some histologically aged bones.
Research published in the Paleobiology journal shows more about the life story of Mysaura pibelsaurum than any other known dinosaur. Sincerely, Holly Woodward Our results suggest that you cannot measure the length of a dinosaur’s bone and assume that it represents an animal of a certain age, Woodward said.
Within our sample, there is great variability in the length of the tibia in each age group. It would be like trying to specify an age based on your height because you know the height and age of another person. Age in histological dinosaurs The only way to determine
Horner is a research sub-writer and curator of the Rocky Museum at MSU, where Mayasaura fossils are republished, discovered and named in 1979. Mayasaura announced the first discovery of the world’s largest embryo and fossil embryo egg.
Based on the immature growth of fossils of baby dinosaurs found in the nest, Horner speculated that they were unable to hate and that they had to take care of the parents, that’s why they called the dinosaur Myasora, in Latin, a good mother. Like lizard. “
The study revealed aspects of the biology of Mayasaura, with its roots in the social colonies and; Mayasaura used to walk on two legs when he was young and four when he was growing up; His favorite foods included rotten wood; And its climate was warm and semi-arid with the possibility of a long dry season.
The tibia included in the paleontology study comes from a single bone that covers at least two square kilometers in western Montana. After more than 30 years of excavation and thousands of fossils, there are no signs that the bone fragment moves. Woodward plans to lead the annual Mayasaura summer excavations to gather more data.
Our study closes the Myasaura Life History Project, which seeks to learn as much as possible about Myasaura and its surroundings, collecting bones and examining bone fossils 76 million years ago.
Continue to do so, adding strength to the sample, he said. We plan to examine other skeletal elements to produce a histological ‘map’ of Mysore, to see if different bones in their bodies have grown at different rates, giving us an idea of their biology and behavior.
Give an idea This allows us to study more aspects of it. We also want to improve. The environment, including the life story of other animals in the ecosystem in which the Mysoura lived.
