Writer/Researcher: Dan DeAmicis Editor: Nancy Sacchetti Web Page Builder: Dan DeAmicis Although it has been known that dinosaurs lay eggs for quite some time little has been known about their nesting habits until recently. Since dinosaurs are most often thought to have resembled reptiles, it was often thought that they had similar nesting habits. It was often assumed that they laid their eggs and then went away. This theory was thought to be backed up by that fact that many egg nests were found without any signs of dinosaurs nearby. Sometimes when dinosaurs were found near by it was thought that they were there to harvest and eat the eggs. In fact, several dinosaurs were named as they were because it was thought that they ate eggs. However, in recent years there has been evidence the dinosaurs nesting habits were more like birds, than like reptiles nesting habits. It has been found that one of the dinosaurs known as "egg eaters" were of the same species as nest they were found near. This finding led many to believe that at least some dinosaurs stayed by the nest and cared for their young. It has been theorized that dinosaurs might have fed their young the same way that birds do, by regurgitating their food into the mouths of their young. Some people have drawn an indirect conclusion between dinosaur nesting habits and whether or not they are warm-blooded. Although there is no direct connection, it has been hypothesized that if dinosaurs had birds-like nesting habits that they are more likely to be warm blooded like birds. As of now there is no conclusive evidence as to whether dinosaurs are warm or cold loaded.
