Experts had long thought that dinosaurs were cold-blooded like the modern reptile, but subsequent research widened the field to include the possibility they had characteristics of both cold and warm blooded creatures.
His conclusion is based on a re-assessment of an unrelated paper published in 2014 which documented the growth rates and metabolic processes of a wide range of species.
Though that research found dinosaurs to be somewhere in between being hot- and cold-blooded, his analysis differed from theirs on two points.
First, he disagreed with the dinosaurs' estimated growth rates because they were scaled from yearly to daily which he considers problematic.
According to him, this does not take into account uneven periods throughout the year which many large, often stressed, animals experience.
Second, he focused on their close lineal relationship to birds which still exist and are warm-blooded creatures.
He plans to further his research by studying other dinosaur remains to determine their metabolic status and variability.

His day job is Chief Technical Officer of Microsoft. Rear is the Diplodocus that has the long tail with the fused sections in all the tails, leading Myhrvold to the belief that the dinosaur cracked its tail like a whip, the end section moving near the speed of sound. - Photo By Craig Herndon TWP (Photo by Craig Herndon/The Washington Post/Getty Images)
Dr Adam Yates, from the Bernard Price Institute for Paleontological Research, looks at the 'Aardonyx Celestae', a newly discovered fossil skeleton in Johannesburg on November 11, 2009. South African palaeontologists announced the discovery of a new species of 'transition' dinosaur that straddles the divide between the four-legged giant plant-eating sauropods and their bipedal carnivorous predecessors. The dinosaur roamed the area between 183 million and 200 million years ago, measured between 7 and 9 metres long. The specimen was a juvenile, which was aged between 7 and 10 years. The Aardonyx Celestae, as the new dinosaur has been named, was discovered on a farm in central Free State province in the Karoo Basin, an area rich in fossils.

UNDATED - In this handout provided by the Carnegie Museum of Natural History, an artist's redering depicts a previously unknown bird-like dinosaur that was formally introduced to the scientific community by scientists with the Smithsonians National Museum of Natural History, the Carnegie Museum of Natural History and the University of Utah March 19, 2014. Dubbed Anzu wyliei, referring both to a mythological feathered demon and the name of a Carnegie museum trustee's grandson, the seven-foot-tall creature weighed about 500 pounds when it roamed western North America 66 to 68 million years ago.
