The debate over dinosaurs being warm-blooded (endothermic) or cold-blooded (ectothermic) has raged on and on, ever since we’ve known of their existence, but recently, a study may have put us toward the right direction. The study, published on PLoS ONE, suggests that they may have in fact been endothermic. This conclusion was reached based on various species’ leg length. Since cold-blooded creatures are slower, it was hypothesized that in order to utilize their bodies properly, they would have had to have been very athletic, which would require being warm-blooded. This would make them agile, high-metabolism creatures. The article itself dives into the particulars, but this may put us closer and closer to what our scale (and feather) friends may have been like.
