Scientists may have solved one of the oldest dinosaur mysteries ...

dinosaurs have long been seen as slow, heavy creatures that roamed the Earth with gigantic feet millions of years ago.

Dinos were long-assumed to be cold-blooded due to their comparison to reptiles; however, experts have long debated this issue.

A Yale-led team of researchers has finally discovered this problem once and for all by developing a new approach for analyzing animals'' metabolic rates, even extinct ones! Their technique focuses on the amount of oxygen they once inhaled in their bones.

Researchers have discovered that the earliest dinosaurs and pterosaurs had extremely high metabolic rates and were, in fact, warm-blooded creatures.

Dinosaurs, metabolism, and oxygen

Substituting metabolism is a slew of chemical events that help sustain human life; this is how successfully we transform the oxygen we breathe into chemical energy that feeds our bodies.

The effectiveness with which an animal transforms oxygen into energy is essentially defined by its metabolism: warm-blooded animals, for example, have high metabolic rates, requiring them to take in more oxygen and eat more water to maintain their body temperature.

This opens up a chain of biochemical events that leave molecular waste products in their bones, indicating that the quantity of waste produced is directly related to the amount of oxygen used.

This basically means that breathing records whether or not the animal was warm-blooded or cold-blooded. The best part is that these identifiers maintain the environmental condition.

Turning up the heat on dinosaur metabolism

According to the papers'' lead author, Jasmina Wiemann, who is affiliated with Yale University and the Natural History Museum of Los Angeles County, the teams findings are very inspiring for us as paleontologists are discovering whether dinosaurs were warm- or cold-blooded, which is, now we believe.

According to a press release, scientists used Raman and FTIR spectroscopy to investigate these chemical markers in the femurs of 55 different animals, including dinosaurs, flying pterosaurs, and marine plesiosaurs. Finally, they then examined the molecular profiles of the latter to those of the extinct animals.

Most mammals, including pterosaurs, plesiosaurs, and theropods (long-necked dinosaurs like Brachiosaurus) were warm-blooded. In fact, some of them had metabolic levels that were higher than mammals and closer to birds. Others, such as Stegosaurus and Triceratops, appeared to have lower metabolic rates than current cold-blooded reptiles.

This discovery is incredibly exciting because it gives fascinating new insights into dinosaurs and other prehistoric creatures. Moreover, the researchers now have a new biomolecular tool to assist paleontologists as well as zoologists.

"Our goal is to provide a more comprehensive picture of how animal physiology relates to past environmental and ecological changes, and to provide insights into the past that will guide future initiatives for biodiversity conservation in the face of global climate change.

Study Abstract:

The metabolic characteristics of mammals and mammals were measured independently in vitro compared to those of mammals and plesiosaurs, while they were superior to those of mammals. The findings suggest that aerobic activity similar to aerobic exercise is necessary in human development. In addition to crown mammals and birds, these factors are shown to be significant.
