Teeth from Thomas the T. rex reveal a human-like body temperature
Tyrannosaurus rex had a body temperature of about 97 degrees Fahrenheit, almost the same as a human's, according to a study published Sept. 16 in Science Advances. It is the first real measurement. UCLA scientists tested portions of two teeth from Thomas the T. rex, held at the Natural History Museum of Los Angeles County, using a method refined over a decade to need roughly 90% less material. The result points to a fast-moving predator or scavenger rather than a sun-basking slowpoke, one able to survive chilly climates deadly to other reptiles.
Palaeontologists get a measured picture of how T. rex lived, and museums can share far less of their irreplaceable fossils for testing.
