The terms ‘warm-blooded’ and ‘cold-blooded’ are used for simplicity throughout this essay. In fact these terms are something of an over-simplification. Virtually all animals, if examined at the proper time, will appear to be ‘warm-blooded’ – i.e. their internal body temperatures will be about the same.
What’s more important is the mechanism by which body temperature is maintained (thermoregulation). Here’s a quick science lesson, like you may learn in a university science course or earlier. The terms endothermic and ectothermic are relevant here. An ectothermic animal relies on heat from the outside i.e. the environment, to maintain body temperature, whereas an endothermic animal relies on heat generated within its own body by metabolic processes, and will therefore have a higher metabolic rate. There are even more precise technical terms for processes intermediate between full endothermy and full ectothermy which will not be discussed here.
Once it was thought that all dinosaurs were cold-blooded. Now many suggest that at least some were warm-blooded, which would help to explain why they became so plentiful and dominant for so long. If we examine today’s fauna, we find no large land predators that are cold-blooded, except for crocodiles that occupy only one very specific ecological niche and are basically water dwellers. The same is true of the entire Cenozoic era. Virtually all large predators were warm-blooded.
The reason is not difficult to find. The position of top predator is a very competitive one. The ability to control body temperature and maintain it at a constant value (i.e. warm-blooded) is a very large advantage. Not only does it mean that the animal is not dependent on the environmental temperature but can hunt at any time of the day (or night), or in any season, but it also means operating at maximum efficiency. All creatures, whether warm- or cold-blooded, use the same basic biochemical processes to produce energy, with the same enzymes and substrates. The chemical reactions involved generally have a particular optimal temperature. For every drop of 10 degrees C, the process will be twice as slow. Hence, the sluggishness of cold-blooded animals in cold environments or at night. Evolutionary theory thus demands that, in any long term competitive situation, warm-blooded animals will always win over their cold-blooded competitors, and this is what the history of mammal development demonstrates. No large cold-blooded predators can develop against mammalian competition. Instead, they remain small and occupy ecologically specialized positions where they can hide for most of the time and only need to hunt for food occasionally when safe to do so.
There are, of course, attendant disadvantages to endothermy, not the least of which is the need for very much larger expenditure of energy to maintain elevated metabolic rates, and a commensurate increase in food requirements.
Given that mammals have such an enormous advantage, what are we to make of the Mesozoic era when, for 140 million years, dinosaurs reigned supreme and few mammals grew larger than a chicken. Mammals and dinosaurs evolved together. Dinosaur ancestors (thecodonts, particularly ornithosuchians) and mammal ancestors (therapsids, particularly cynodonts) were in direct competition in the late Triassic, with the therapsids initially appearing to have the upper hand. However, by the end of the Triassic the thecodonts were on top, dinosaurs assumed the roles of top predator and large herbivore, and all other roles down to the very small, which they left to the mammals and other reptiles. How did they manage to take over in the first place, and then keep the mammals subservient for so long if mammals had such a potent evolutionary advantage in being warm-blooded? The logical answer, of course, is that dinosaurs had to be warm-blooded as well! For those who believe that dinosaurs are just large reptiles this is an unacceptable view.
Given that all we have left are lifeless bones and footprints, is it possible to produce evidence in support of the warm-blooded dinosaur hypothesis? Surprisingly, perhaps, the answer is yes, although such evidence must be largely inferential.
Some of the evidence has already been presented above, in the comparison of dinosaurs with present day ecological structures. Other evidence comes from areas such as:
Bone structure and histology
Speed and agility
Rate of evolution
Similarities with birds
Bone Isotope Composition
All these lines of evidence and comparisons between dinosaurs, mammals and cold-blooded reptiles support the idea that dinosaurs were warm-blooded, or at very least had a much higher metabolic rate than conventional cold-blooded creatures. Not surprisingly, some counter arguments have been presented, such as:
The question is yet to be decided, but on balance the likely outcome seems to be heavily weighted in favour of at least partially warm-blooded dinosaurs. The tests for endothermy have also been applied to the mammal ancestors (the therapsids: cynodonts, dicynodonts) and thecodont dinosaur ancestors. In both cases the results suggest that they were more like warm-blooded than cold-blooded animals, and that endothermy may have developed in both lines at an early period (late Permian ?). In this scenario, dinosaurs would simply be one group in a line of succession of warm-blooded animals.
What does seem clear is that dinosaur physiology was different, and may even have been different in different types of dinosaurs. We can never know the answer by direct measurement, and as long as we are forced to rely on analogy we will probably never reach a consensus on this controversial topic. Endothermy is not an either/or proposition, as the large number of potential physiological mechanisms involved make a wide range of alternatives possible. The large size range of dinosaurs alone probably means that they did not all share a common physiology, nor use the same strategies and mechanisms to reach a particular physiological state.
The word “bizarre” is often used to describe dinosaurs, but Therizinosaurus is bizarre by even dinosaur standards. It has the long neck, small head and tiny, leaf-shaped teeth of a sauropod. However, it isn’t a sauropod but a theropod. Yet, unlike other theropods, it was a plant-eater! This dinosaur had other strange features, including a broad potbelly and incredibly long finger claws. Most paleontologists believe Therizinosaurus was the reptilian analog of the giant (extinct) ground sloth, and those huge claws were probably used to pull down leafy branches close to its mouth.
Originally a site for the promotion and illustration of dinosaur and vertebrate paleontology art (to view or for sale) this page now also features companies that sell fossil replicas. I have chosen to feature those companies who offer fine fossil reproductions for sale a practice I want to encourage so that the original specimens end up at institutions rather than in private collections where many of them become lost to research. Since this is a new addition to this page I would welcome any additional web sites where fine fossil replicas may be purchased from companies promoting the philosophy that significant vertebrate specimens end up in research institutions through the sale of these replicas. Enjoy! Dino Russ

Dinosaur Murals by Beverly Leesman. Watercolor artist Beverly Leesman who for the last fifteen years, Leesman has devoted her talents to the exploration of realistic watercolor based on her own photographs has now expanded into some dinosaur art in a mural that she is making for the Birthday Party Room at Gold Cup Gymnastics. Other than the famous Peabody Mural have not seen too many murals lately.
Chris Srnka , an illustrator living in Columbus, Ohio. He is a graduate of the Columbus College of Art and Design. He will do a wide variety of freelance work, but dinosaurs are by far his favorite subjects. He currently designs billboards in Columbus, along with the freelance work. The dinosaur images were first sketched on paper, then scanned into his computer. He used Metacreation’s Painter 5.0 to paint the dinos. Painter emulates traditional media, allowing for a wide range of tools and styles. Although the art is digital, it is all hand drawn, using Painter and a pressure-sensitive drawing pad.

The Age of Reptiles Mural at the Yale Peabody Museum. The vivid scene reproduced from Rudolph Zallinger’s famous dinosaur mural The Age of Reptiles, overlooking the Great Hall in Yale’s Peabody Museum, is far more than a magnificent work of art. It is also a scientific document transforming the knowledge, ideas, and thoughts of many scholars of ancient life into realistic and accurate images. The mural is one of the largest in the world, measuring 110 feet long by 16 feet high, and required more than four and a half years (1943-1947) to complete. It is at once a motion picture and a time machine, a menagerie and a botanical garden that portrays an almost unimaginable chapter of earth history spanning more than 300 million years. The animals and plants of this panorama — most never having been seen by human eyes — have been resurrected for our contemplation and wonderment. Here, the textbook names take on new meaning; our mind’s eye perceives the reality and magnificence of unfamiliar plants and communities of astonishing animals.

Raymond Persinger. Raymond was one of the first sculptors hired by Dinamation. During his time at Dinamation he personally sculpted and/or directred teams in the creation of more than 70 dinosaurs. These range in size from small scale models to a 50 foot T-rex. His work has been exhibited in museums around the world including the Smithsonian in Washington D.C. He was personally selected by National Geographic to sculpt a static flying Pteranodon for their permanent collection. Besides serving in an artistic capacity Raymond’s abilities as an inventive problem solver proved to be an invaluable asset to Dinamation. He helped develop robotics, inovative mold making and production techniques, create exhibits and interfaces with museums and the public as a field service specialist. Ray would be interested in creating work for museums and/or working directly with paleontologists in developing sculptural representations of their finds/theories.Check out his website and see examples of his work. There is also information on contacting Ray for your own museum exhibits and displays. Because of Raymond’s numerous accomplishments, Dinamation’s VP’s often referred to him as the “Merlin of Dinamation” and Science Director Robert Bakker stated that Dinamation would never have existed were it not for Raymond’s many contributions. Some very great work, I have seen many of the robotic dinosaurs at Fruita (at the former Dinamation museum, now Dinosaur Journey – Museum of Western Colorado)in past few years and other places. Some very nice work.

Paper Dinosaurs, 1824-1969. An Exhibition of Original Publications From the Collections of the Linda Hall Library The Linda Hall Library is now presenting an exhibition of original printed materials related to the history of dinosaur discovery. On view are most of the classic papers of dinosaur lore, including the original publications of Gideon Mantell, Richard Owen, Othniel Marsh, and a host of others. The focus of the exhibition is on images, both of discovery and of restoration. The exhibition runs from October 17, 1996 through April 30, 1997. What follows is a hypertext catalog of the exhibition. It proceeds through all forty-nine items of the exhibition, but includes links to thirty-five more works that could not be accommodated in the exhibition hall. There are 136 original images.

Stygimoloch was a small pachycephalosaur whose thick skull bristled with bony knobs and spikes. It undoubtedly engaged in head-butting, either for defense or to establish a pecking order during mating, or perhaps both. Its name derives from the river Styx (“stygi”) and the name of a Semitic god, Moloch. In Greek mythology, the Styx was a mythical river flowing through the underworld near Hades (Hell). Stygimoloch’s remains were discovered in the Hell Creek formation of Montana and Wyoming. According to myth, children were fed to the god Moloch. However, even if there had been any youngsters around in the Cretaceous, they would have been in no danger of being eaten by Stygimoloch since it was a vegetarian.

Books are still a more important resource and the best one for dinosaur information. I recommend the following:
Currie, P.J., and K. Padian, (eds.), 1997, “Encyclopedia of Dinosaurs,” Academic Press, 869 pages. This book is a good encyclopedia of information, current ideas on dinosaurs in one encyclopedia. Topics are short but at least give you information on many ideas and information that current for the field of dinosaur study.
Glut, Donald, 1997, “DINOSAURS: THE ENCYCLOPEDIA,” McFarland,1076 pp. Of the three listed this book is number one in my collection because it contains information about every dinosaur known as of 1997. So if you are looking for information on a well known or an obscure dinosaur for your research then this book should be number one on your list of references to check! This is probably the biggest number of questions I am asked. Teachers and students alike: I will not do this kind of research for you, you need to find a source for this book yourselves. While I would love to have the time to provide some of the data found in this book you do not learn something if I type it in for you. If you can afford it (it is $150) I recommend you add it to your own personal library. If not perhaps you can get your local public library to purchase a copy – this should be the number one dinosaur reference in their collection.
Farlow, J.O., and M.K. Brett-Surman, (eds.), 1997, “The Complete Dinosaur“, Indiana University Press, 752 pages. Next to the second reference above this is a must in your own reference collection. This is a well written book at the general level that covers all current topics and areas of knowledge in the dinosaur field of science and what is known about the various groups of dinosaurs.
Fastovsky, D. E. and D. B. Weishampel, 2005, second edition, “The Evolution and Extinction of the Dinosaurs,” Cambridge University Press, ISBN: 0521811724, 512 p. This recent book is written in an easy to understand style, basically an entry level college course type book so any dinosaur enthusiast should find this book quite educational. Makes an excellent companion book on your shelf to the more technical Dinosauria listed above . Book presents in a condensed and simpler manner the general info in dinosaurs found in Dinosauria, but with new thinking and ideas of scientists that has come to light since the publication of Dinosauria. This is a definite “must have” on your bookshelf! Other reviews (of 2nd edition) Written for non-specialists, this detailed survey of dinosaur origins, diversity, and extinction is designed as a series of successive essays covering important and timely topics in dinosaur paleobiology, such as “warm-bloodedness,” birds as living dinosaurs, the new, non-flying feathered dinosaurs, dinosaur functional morphology, and cladistic methods in systematics. Its explicitly phylogenetic approach to the group is that taken by dinosaur specialists. The book is not an edited compilation of the works of many individuals, but a unique, cohesive perspective on Dinosauria. Lavishly illustrated with hundreds of new, specially commissioned illustrations by John Sibbick, world-famous illustrator of dinosaurs, the volume includes multi-page drawings as well as sketches and diagrams. First edition Hb (1996): 0-521-44496-9
Weishampel, D.B., P. Dodson, and H. Osmolska (eds.), 2004, “The Dinosauria,” University of California Press: Berkeley. 861p. Simply put, the definitive text on dinosaurs. Now out in a second edition (December 2004) this is probably your most important reference and a must have. When the The Dinosauria was first published more than a decade ago, it was hailed as “the best scholarly reference work available on dinosaurs” and “an historically unparalleled compendium of information.” This second, fully revised edition continues in the same vein as the first but encompasses the recent spectacular discoveries that have continued to revolutionize the field. A state-of-the-science view of current world research, the volume includes comprehensive coverage of dinosaur systematics, reproduction, and life history strategies, biogeography, taphonomy, paleoecology, thermoregulation, and extinction. Its internationally renowned authors-forty-four specialists on the various members of the Dinosauria-contribute definitive descriptions and illustrations of these magnificent Mesozoic beasts. The first section of The Dinosauria begins with the origin of the great clade of these fascinating reptiles, followed by separate coverage of each major dinosaur taxon, including the Mesozoic radiation of birds. The second part of the volume navigates through broad areas of interest. Here we find comprehensive documentation of dinosaur distribution through time and space, discussion of the interface between geology and biology, and the paleoecological inferences that can be made through this link. Illustrations: 330 line illustrations, 28 tables. Available from Amazon.com click here.

Dinosaur Dreaming – MONASH UNIVERSITY Dinosaur/VP PALEO SITE. The Australian university has an on-line paleo site where you can learn about its ‘Dinosaur Dreaming’ expeditions. Dinosaur Dreaming is part of a successful project between Museum Victoria and Monash University, the Dinosaur Dreaming fossil excavations at Inverloch over the last 12 years have yielded not only fascinating insights to the life and times of Australia’s Dinosaurs, but also highly significant and intriguing fossil mammals. Inverloch: Home of Dinosaur Dreaming is the Victorian coastal town near which the Dinosaur Dreaming site is located. About 145 kilometres (ninety minutes drive) from Melbourne, Inverloch is a very civilised place from which to do field research.The site is a rocky shore platform called Flat Rocks, about five minutes’ drive from the township on a stretch of coast favoured by surfers and fishing enthusiasts. This is where the Cretaceous mammal, Ausktribosphenos nyktos, was found in March 1997… READ MORE
Dig It! The world renowned Jurassic Morrison Formation covers more than 350 square miles from Canada to New Mexico and contains every conceivable environment from dry deserts to swamps. Join Paleontologist and Education Specialist Peter Laraba on this two-day e-field trip as he takes an expedition to Colorado and Utah to explore the Morrison Formation by sampling two of its many environments. On September 28th, they explored a working dinosaur quarry in Grand Junction, Colorado, joining scientists and volunteers in the discovery and excavation process. We got into the “trenches”, working with Utah State paleontologist Dr. James Kirkland, the discoverer of the first Utahraptor skeleton, to uncover the secrets of a Jurassic watering hole. On September 29th, they went to the world famous Dinosaur National Monument. Although still in the Morrison Formation, the environment of deposition along the banks of a large river system is very different from the watering hole of the previous day. National Park paleontologist Dan Chute will be your guide through the rich history of the area and reveal some of the treasures yet to be discovered in this unique park.
