A new tooth test suggests T. rex was not cold-blooded like modern reptiles; the giant predator’s body temperature was estimated at a human-like 97°F

Recent studies reveal fascinating insights into the body temperature of the mighty T. rex. Researchers have found that this colossal predator maintained a warm body temperature of approximately 36 degrees Celsius. This surprising evidence, derived from analyzing rare isotopes within fossilized tooth enamel, indicates that T. rex was likely an energetic hunter in various climates, capable of thriving even in cooler environments.
