Some Obscurish facts

Most scientists are now saying that dinosaurs were very unlike lizards. Their legs were usually directly under their bodies, not sticking out from their sides like lizards. Their bone structure was more like that of warm-blooded mammals. Tracks have been found made by of groups of dinosaurs moving together in herds with a spacing and depth of impression indicating sustained high speed, again more a mammalian trait than reptilian. One theory regarding the extinction of dinosaurs which is gaining some acceptance is that because they were warm-blooded creatures with a high metabolism, they were more susceptible to viruses or bacterial infections than their cold-blooded predecessors. According to one scientist, they might have all died of diarrhea. Can you imagine the mess?
