It’s one of paleontology’s oldest questions, and gleaning the answer matters because it illuminates how the prehistoric creatures may have lived and behaved.Challenging the prevailing idea that they were all slow, lumbering lizards that basked in the sun to regulate their body temperature, research over the past three decades has revealed that some dinosaurs were likely birdlike, with feathers and perhaps the ability to generate their own body heat.However, it’s hard to find evidence that unquestionably shows what dinosaur metabolisms were like. Clues from dinosaur eggshells and bones have suggested that some dinosaurs were warm-blooded and others were not.A new study published in the journal Current Biology on Wednesday suggested that three main dinosaur groups adapted differently to changes in temperature, with the ability to regulate body temperature evolving in the early Jurassic Period about 180 million years ago.Based on fossils from 1,000 dinosaur species and paleoclimate information, the new study looked at the spread of dinosaurs across different environments on Earth throughout the dinosaur era, which started some 235 million years ago and ended 66 million years ago when an asteroid slammed into Earth.Two of the three main groups — meat-eating therapod dinosaurs, which included T. rex, and plant-eating ornithischians, whose notable members included Triceratops and Stegosaurus — spread to live in colder climates during the early Jurassic Period, the research suggested. These dinosaurs may have evolved endothermy, or the ability to internally generate body heat, according to the study.Visitors look at the skeleton of a gigantic Triceratops over 66 million years old, named “Big John,” on display before its sale at Drouot auction house in Paris in October 2021. – Sarah Meyssonnier/ReutersTwo adaptable dinosaur groupsTherapods and ornithischians lived in a b …
