This mural was originally made for a recent Royal Ontario Museum exhibit about a fossil ankylosaur named Zuul crurivastator. That fossil is found within a couple of meters stratigraphically/temporally of the site described in this paper. The last author on the study, David Evans, is the dinosaur curator at the Royal Ontario Museum and was also involved in the description of Zuul and design of that exhibit.

CT scan-generated models of the jaws of Majungasaurus (left), Ceratosaurus (center) and Allosaurus (right), with microscopic views of the interior of their teeth below each model. Stripes running from upper left to lower right in each microscopic image are daily deposited incremental lines, which allow the amount of time it took for a tooth to grow to be reconstructed.

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. New research 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. Credit: Life restoration by Michael Skrepnick.
