Dinos in D&D

POPULAR CULTURE AND SCIENCE

Because dinosaurs are an important part of popular culture and hence are easily recognizable, the study of them serves as an apt vehicle for understanding how science is applied to their study. A starting point for applying the science of dinosaur studies is to understand what is or is not a dinosaur, using a definition as a prompt for asking questions, as a large number of animals regarded as dinosaurs actually are not. A dinosaur is defined initially as a reptile-like or bird-like animal, with an upright posture, that spent most (perhaps all) of its life on land and lived from about 230–65 million years ago. Dinosaurs then can be classified by either a Linnaean or phylogenetic (cladistic) classification system. The cladistic method is preferred because it better expresses hypotheses about evolutionary relatedness within dinosaurs as a group. These hypotheses are best described through a cladogram, a diagram that shows ancestor-descendant relationships.




The two sciences most commonly associated with dinosaur studies are geology and biology, which are also augmented by other sciences, such as chemistry, physics, math, and computer science. Their use illustrates how the interrelation of all sciences can contribute to a field of study. Despite the apprehension of many people about the sciences, especially those that frequently use symbols and numbers, it is necessary to know a minimal amount about them to better understand dinosaurs. Professional paleontologists typically have to know some facets of all scientific disciplines. In many cases they also must be illustrators, writers, public speakers, and deal with the physical and logistical difficulties of performing fieldwork in remote locations.



Popular culture, such as books, TV shows, movies, artwork, and Web pages, reflect public ideas about dinosaurs that may or may not be based on scientific reality but they can follow general scientific trends. Whenever encountering these images of dinosaurs, the question of “What evidence justifies these depictions?” should be asked. However, of all dinosaur artwork, scientific illustration is the most important with regard to dinosaur studies and combines scientific knowledge with artistic abilities to convey accurate information.



Math is an essential tool for dinosaur studies and is expressed mostly through measurements, which are made through the international standard of the metric system. Math can be used in nearly every aspect of dinosaur studies, as demonstrated by the use of some simple calculations of estimated dinosaur weights based on their models. Such step-by-step methods help to show that math has practical uses in dinosaur studies and can be made more understandable in an applicative context.

Warnings

The dinosaurs, and many other creatures such as the pterosaurs, mosasaurs, and ammonoids, went extinct at the end of the Cretaceous. There is considerable evidence that dinosaurs, after reaching a peak of diversity about seventy-four million years ago, began a gradual decline. Unquestionably, though, something delivered the coup de grâce. In Chapter 8 I tell the story of the bitter, vicious controversy that raged over the reasons for the mass extinction that ended the Mesozoic. Many regard the dinosaurs’ demise with sadness. Many a kid has fantasized that somehow, somewhere, there is a lost forest where T. rex continues to prowl. But if the dinosaurs had not gone extinct, it would be most unlikely that we would be here. During the Mesozoic, our mammalian ancestors were small, nondescript, probably nocturnal creatures. While dinosaurs were dominant, there simply was no free ecological space for large mammals to occupy. Only after the extinction of the dinosaurs did the remarkable evolutionary radiation of mammals occur.

The dinosaurs were the lords of the Mesozoic. Their demise offers a deep lesson to us: The earth does not grant tenure. On the contrary, 99 percent of all species that have ever lived are now extinct. Even more sobering is the realization that several different hominid species have lived on Earth. Only one survives—Homo sapiens. We tend to think that the “sapiens” part of that name, our intelligence, gives us an edge that will allow us to escape the fate of other species. Well, we certainly have been successful in the short term—there are six billion of us on the planet, making us by far the most numerous species of large animal. By contrast, only about two thousand tigers survive in the wild. But the deepest lesson of the dinosaurs is the awful, incomprehensible depth of time. Sixty-five million years from now, will any of our descendants be alive? If so, will they be in any sense human? Will they remember any of our literature, our art, our science, our religions? After all, geological time shows that the only thing permanent is the fact of change. Evolution on Earth began with the first self-replicating molecules four billion years ago, and it will continue until the sun dies.

Dinosaurs - Recommended Reading

These include the anthology The Complete Dinosaur, edited by J. O. Farlow and M. K. Brett- Surman; David Norman’s Illustrated Dinosaur Encyclopedia; John Noble Wilford’s The Riddle of the Dinosaur; and Don Lessem’s Dinosaurs Rediscovered (originally titled The Kings of Creation). Almost as valuable as the Farlow and Brett-Surman anthology is the Encyclopedia of Dinosaurs (San Diego: Academic Press, 1997), edited by P. J. Currie and K. Padian. Good books on particular types of dinosaurs include John Horner and Don Lessem’s The Complete T. rex (New York: Simon and Schuster, 1993) and Peter Dodson’s The Horned Dinosaurs (Princeton, NJ: Princeton University Press, 1996). Gregory S. Paul’s Predatory Dinosaurs of the World (New York: Simon and Schuster, 1988) is interesting and contains the author’s own excellent illustrations but makes many very controversial claims about how fast these creatures ran and how they lived.

Some of the most interesting recent books on dinosaurs attempt to reconstruct their lives and habits. John Horner’s books can be particularly recommended as works that try to tell us about dinosaur behavior and lifestyles. His book Digging Dinosaurs: The Search That Unraveled the Mystery of Baby Dinosaurs (New York: Workman, 1988), cowritten with J. Gorman, tells about his discovery of dinosaur eggs and nests. These discoveries prompted Horner to name one dinosaur Maiasaura, which means “good mother lizard,” because of evidence that it kept nests and nurtured its young. A more recent book coauthored with E. Dobb, Dinosaur Lives: Unearthing an Evolutionary Saga (San Diego: Harcourt Brace, 1997), gives evidence for other aspects of dinosaur behavior.

There are two college-level textbooks on dinosaurs, Dinosaurs: The Textbook by Spencer G. Lucas (Dubuque, IA: William C. Brown Publishers, 1994) and The Evolution and Extinction of the Dinosaurs by David E. Fastovsky and David B. Weishampel (Cambridge: Cambridge University Press, 1996). Both are very good, well illustrated, and considerably livelier than the usual cut-and-dried textbooks.

A word of caution: There are many good books on dinosaurs. I have been able to list only a few of them here. However, there are also many very bad books on dinosaurs, especially books for children. These books are often written by people who do not know much about dinosaurs and who don’t mind making a few bucks by passing on their ignorance to others. Some years ago Don Lessem and other paleontologists formed the Dinosaur Society to safeguard against misinformation. If a book bears the seal of the Dinosaur Society, it will contain accurate information—otherwise, caveat emptor.

ITV1 saves Primeval from extinction after deal with digital channel Watch

'Groundbreaking' deal to share costs with UKTV channel Watch prompts ITV1 to announce 13 new episodes over two series"

Leigh Holmwood

Dinosaur drama Primeval has been rescued from extinction three months after ITV1 said it would not recommission the programme – thanks to a "groundbreaking" deal to share costs with a digital channel.

MediaGuardian.co.uk revealed in May that producer Impossible Pictures was trying to put together a deal to save the show, in which a group of scientists in present-day Britain fight prehistoric and futuristic creatures that have been transported through time. But ITV announced in June that it would not proceed.

However, ITV today said it had agreed to share the next two series, comprising 13 episodes in total, with UKTV channel Watch after a deal was hammered out by Impossible Pictures and partner BBC Worldwide, which distributes the show internationally.

In the new funding structure BBC Worldwide has overtaken ITV to become the largest partner, with BBC America – which broadcasts the series in the US – joining Germany's Pro7 as a co-production partner.

ITV1 will premiere the fourth series of the show in early 2011. Watch – which already airs sci fi shows Doctor Who and Torchwood – will repeat it soon after and then premiere the fifth series later the same year, followed by ITV1.

The new series will reunite the stars from the previous series, including Hannah Spearritt, Andrew-Lee Potts and Jason Flemyng, alongside the acclaimed special effects created by Framestore CFC. Showrunner Adrian Hodges will oversee the series.

Tim Haines, creative director of Impossible Pictures, said: "I am thrilled that ITV has agreed to this new deal, which will allow Impossible Pictures to produce another 13 episodes of Primeval. The confidence demonstrated in the programme's continued success here and abroad will help us bring more big-screen action and a whole host of new creatures roaring back into people's living rooms."

Laura Mackie, director of ITV drama commissioning, added: "We're delighted to have agreed this new deal with Impossible to return Primeval to ITV1. The innovative nature of this partnership will allow the show to maintain its high production values."

The third run of Primeval launched with 5.3 million viewers in April. Impossible Pictures is developing a film version.

ITV also announced the axing of its other Saturday teatime drama, Demons, in June, saying it wanted to concentrate on its peaktime drama.

Primeval has sold to more than 45 countries worldwide, including Australia, Singapore and South Korea.

What If...Dinosauroid

A theoretical reptilian humanoid has also been the focus of a widely discussed thought experiment in speculative evolution. In particular, in 1982 paleontologist Dale Russell, curator of vertebrate fossils at the National Museum of Canada in Ottawa, conjectured a possible evolutionary path that might have been taken by the dinosaur Troodon (then called Stenonychosaurus) had they not all perished in the K/T extinction event 65 million years ago. The essence of this thought experiment was that bipedal predators (theropods) which existed at that time, such as Troodon, could have evolved into intelligent beings similar in body plan to humans. Over geologic time, Russell noted that there had been a steady increase in the encephalization quotient or EQ (the relative brain weight when compared to other species with the same body weight) among the dinosaurs. Russell had discovered the first Troodontid skull, and noted that, while its EQ was low compared to humans, it was six times higher than that of other dinosaurs. If the trend in Troodon evolution had continued to the present, its brain case could by now measure 1,100 cm3; comparable to that of a human. Troodontids had semi-manipulative fingers, able to grasp and hold objects to a certain degree, and binocular vision.

Description

Russel proposed that this Dinosauroid, like most dinosaurs of the troodontid family, would have had large eyes and three fingers on each hand, one of which would have been partially opposed. As with most modern reptiles (and birds), he conceived of its genitalia as internal. Russell speculated that it would have required a navel, as a placenta aids the development of a large brain case. However, it would not have possessed mammary glands, and would have fed its young, as birds do, on regurgitated food. He speculated that its language would have sounded somewhat like bird song.

Criticism

Russell's thought experiment has been met with criticism from other paleontologists since the 1980s, many of whom point out that Russell's Dinosauroid is overly anthropomorphic. Gregory S. Paul (1988) and Thomas R. Holtz Jr., consider it "suspiciously human" (Paul, 1988) and argue that a large-brained, highly intelligent troodontid would retain a more standard theropod body plan, with a horizontal posture and long tail, and would probably manipulate objects with the snout and feet in the manner of a bird, rather than with human-like "hands".

 

Dino is Angry at World

21 May 07 Today's Kongcept artwork comes from Greg Broadmore, who created a Mr "Angry at the World" Dino for Peter Jackson's King Kong.
Greg explains how this illustration came about:
"This illustration was relatively late in the design process and was actually for what ended up being the quadrupedal crocodile like reptile that attacks Anne in the log: 'Foetodon'.
"At the time we had no idea of the nature of the scene that this creature would appear in, all we knew was that it had to be a new dinosaur. Although we quickly found out that this would be a quadruped, at this point anything was open. I did this guy as a medium to large sized therapod but with a slightly more upright and so 'classic' dinosaur posture. It has huge blades as it's front claws.
"I really enjoyed getting to just make up a dinosaur, I do that anyway for fun, so this was just a great opportunity to have fun with design. I really got into the weight and texture of the skin, I love doing that stuff."
