Recent studies confirm T. rex maintained a stable body temperature of approximately 97°F, similar to humans and elephants, indicating warm-blooded metabolism. New fossil evidence suggests these massive predators were largely solitary but engaged in complex social behaviors, including courtship displays and parental care, while hunting via ambush rather than high-speed chases.
Researchers have identified the first confirmed trackway of an adult Tyrannosaurus rex, offering the first direct evidence of its walking speed. Discovered in North Dakota’s Hell Creek Formation, the 66.5-million-year-old prints indicate the dinosaur moved at approximately 3.5 to 4.5 mph, a pace comparable to a brisk human walk. The finding, published in the Journal of Vertebrate Paleontology, resolves long-standing debates about T. rex locomotion by providing behavioral data that skeletal fossils cannot capture. Three of the four footprints are slated for excavation and transport to the Denver Museum of Nature & Science for further analysis of skin and tissue impressions.
Researchers have identified the first known trackway of an adult Tyrannosaurus rex, discovered in North Dakota’s Hell Creek Formation. The four-to-five footprints, dating to 66.5 million years ago, indicate the dinosaur walked at approximately 1.6 meters per second, comparable to a brisk human pace. Published in the Journal of Vertebrate Paleontology, the find provides rare behavioral data on T. rex movement, with three prints set for transport to the Denver Museum of Nature & Science.
A partial Tyrannosaurus rex skeleton, nicknamed 'Rex Jr.', was discovered on a ranch in Newcastle, Wyoming. Researchers believe the specimen could be the most significant T. rex find in decades due to its completeness and condition. The discovery highlights the ongoing importance of the Hell Creek Formation for understanding the final days of the dinosaur era.
A new study in Science Advances provides the first direct measurement of Tyrannosaurus rex body temperature, finding it ran at approximately 36.3°C (97.3°F). This temperature, similar to modern humans and elephants, confirms T. rex was warm-blooded and capable of inhabiting colder regions like Alaska, distinct from the cooler temperatures of contemporary reptiles.
A new study published in Science Advances uses isotope analysis of fossilized teeth to determine that Tyrannosaurus rex had a body temperature of approximately 36°C (97°F), similar to modern humans and elephants. This finding confirms T. rex was warm-blooded and capable of thriving in diverse climates, including Arctic regions, challenging older views of dinosaurs as sluggish reptiles.
A high school teacher's 2025 discovery in North Dakota has led to the identification of the first confirmed trackway of an adult Tyrannosaurus rex. The 23-foot sequence of four footprints, dating to 66.5 million years ago, provides rare data on the dinosaur's walking speed and gait.
A UCLA study published in Science Advances confirms that Tyrannosaurus rex was warm-blooded, with a body temperature of approximately 97.3 degrees Fahrenheit. By analyzing carbon and oxygen isotopes in tooth enamel from two specimens, including 'Thomas the T. rex,' researchers determined the dinosaur’s metabolic heat was comparable to modern elephants and large birds. This finding supports the theory that T. rex was an active predator capable of surviving in diverse climates, including high latitudes, rather than a sluggish, cold-blooded ambush hunter.
A new study published in Science Advances uses carbon and oxygen isotope analysis of fossilized teeth from 'Thomas the T. rex' to estimate the dinosaur's body temperature at approximately 97°F (36°C). This finding provides the first direct thermal measurement, confirming that T. rex was warm-blooded and capable of sustaining high metabolic activity across diverse climates, from Mexico to Alaska.
A new study in Science Advances confirms Tyrannosaurus rex was warm-blooded by analyzing carbon-oxygen isotopes in fossil teeth. Researchers determined the dinosaur’s body temperature was approximately 97°F (36°C), similar to humans and large mammals. This finding resolves a decades-long debate about dinosaur metabolism and supports the theory that T. rex could thrive in cold climates, such as the Arctic, unlike cold-blooded reptiles.
Researchers have identified the first known trackway of an adult Tyrannosaurus rex in the North Dakota badlands. The 23-foot sequence of four footprints, dating to 66.5 million years ago, was discovered in 2025 by a volunteer teacher and published in the Journal of Vertebrate Paleontology. The find offers rare insights into the predator's locomotion, with three prints set to be airlifted to the Denver Museum of Nature & Science for study.
Scientists have confirmed the first known trackway of an adult Tyrannosaurus rex, discovered in the Hell Creek Formation of southwestern North Dakota. The 23-foot-long series of four footprints, dating to 66.5 million years ago, provides rare evidence of the dinosaur's movement, indicating it walked at a casual pace of 3.5 to 4.5 mph. The find, identified by its massive size and narrow toe shape, was discovered by a high school teacher and will be partially excavated for display at the Denver Museum of Nature & Science.
Researchers have confirmed the first known trackway of an adult Tyrannosaurus rex, discovered in 2025 in North Dakota. The 23-foot sequence of four footprints, dated to 66.5 million years ago, indicates the dinosaur was walking at a slow pace of 3.5 to 4.5 mph, offering rare behavioral data.
Researchers have identified the first known trackway of an adult Tyrannosaurus rex in southwestern North Dakota. The four connected footprints, dating to 66.5 million years ago, suggest the massive predator was walking at a brisk human pace of 3.5 to 4.5 mph. The discovery, documented via 3D scanning, offers rare behavioral insights into T. rex movement, as previous finds were isolated single prints. Three of the footprints are scheduled for recovery and transport to the Denver Museum of Nature & Science this fall.
