Photographs of the study site at the White Sands National Monument, New Mexico: (a) ‘ghost tracks’ - the surface expression of the tracks is poor as can be seen from the image and they can only be seen under specific moisture and salt conditions; scale bar - 500 mm from target to target; (b) tracks at the study site excavated to reveal both human and mammoth tracks; (c) ground-penetrating radar (GPR) equipment used in this study; (d) gridded foam mats used to protect the surface during the GPR survey; (e) excavated human tracks at the study site.

This painting depicts an asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatan Peninsula in what is today southeast Mexico. The aftermath of this immense asteroid collision, which occurred approximately 65 million years ago, is believed to have caused the extinction of the dinosaurs and many other species on Earth. Shown in this painting are pterodactyls, flying reptiles with wingspans of up to 50 feet, gliding above low tropical clouds. Image credit: Donald E. Davis / NASA.

Gigantic dinosaurs like the sauropod Diplodocus, which weighed over 15 tons and was longer than an 18-wheeler truck, would have had problems with potentially lethal overheating. Hot blood from the body core would have been pumped to the head, damaging the delicate brain. The new study shows that in sauropods, evaporation of moisture in the nose and mouth would have cooled extensive networks of venous blood destined for the brain. Other large dinosaurs evolved different brain-cooling mechanisms, but all involving evaporative cooling of blood in different regions of the head.
