Dinosaurs is first defined as a group of diverse reptilian population under the name “Dinosauria”(Owen). These reptilian population became the dominant vertebral species after the Triassic–Jurassic extinction around 201 million years ago, and went extinct during the Cretaceous–Paleogene extinction event around 66 million years ago. Dinosaur is a novel population for a design research due to the facts that: 1) The dinosaurs are the under studied population due to geological, and chronological challenges (in term of the design research). 2) The dinosaur population exhibits interesting biological morphologies that would influence and yield an interesting design outcomes. And 3) The dinosaurs have been a subject of many interests from children to a computational biologist (Chi), and certainly the author of this paper.
Based on the the fact that all members of the dinosaur population have been long gone from the earth, and there is a current limitation on a time traveling technology. The only way, we can conduct a population research on the dinosaur is through the studies of paleontology and evolutionary biology. The species of dinosaurs belong to a group known as “archosaurs”, which also includes crocodilians. Within the archosaur group, the dinosaurs are differentiated most noticeably by their gait. Dinosaur legs extend directly beneath the body, whereas the legs of lizards and crocodilians sprawl out to either side (Brusatte).
Dinosaurs are divided into two primary branches, Saurischia and Ornithischia. Saurischia includes those taxa sharing a more recent common ancestor with birds than with Ornithischia, while Ornithischia includes all taxa sharing a more recent common ancestor with Triceratops than with Saurischia (Benton).
Extensive morphological studies of dinosaur fossils led researchers to hypothesize that dinosaur exhibits many behaviors that resemble the behavior of modern avians and reptiles such as food hunting, nesting, courtship. These behaviors in the ginormous body of dinosaurs required high volume of energies and food consumptions. Therefore, thermal regulation of the dinosaurs is an on-going area of research that interested many scholar.
Previously, the arguments about dinosaur’s body temperature have been made for both endothermic and ectothermic metabolisms on the basis of differing methodologies (Eagle). However, the recent finding using isotope thermometry to determine body temperatures from the fossilized teeth of large Jurassic sauropods indicate body temperatures of 36° to 38°C, which are similar to those of most modern mammals. (Eagle). Even though dinosaurs are diverse in forms and sizes, the understanding of dinosaur’s body temperature helps researcher understand hypothesize further on the notion of metabolic pathway and how it’s related to the extinction of dinosaur (Russell).
