Art Through the Years
Sloan and other artists say that one of the most significant impacts on dinosaur art was widespread acceptance in the 1980s of Wyoming-based independent paleontologist Robert Bakker's theory that dinosaurs were warm-blooded.
"You start to see a dramatic change in dinosaur art," said Sloan. "All of the sudden they were running fast, rearing up, charging. That was a very quick change."
More recently, the flood of small and medium sized dinosaurs being unearthed in northeastern China along with insects, fish, plants, and other mammals is giving scientists unprecedented detail on what the environment was like at the time of the dinosaurs.
In addition, a new generation of researchers is delving into areas once considered the fringes of dinosaur science, such as biomechanics where scientists study how dinosaurs walked or with what bite force T. rex splintered bones.
"Adding up all these things allows the artists to show dinosaurs in ways they have never been shown before," said Sloan.
Artwork has evolved from static images of a dinosaur standing around eating a plant to aerial and worm's-eye views of dinosaur communities in action, making the art much more like a natural history documentary than pictures of monsters people half believe in, said Sibbick.
"We are looking at them as more dynamic creatures with more complicated lives and with more complicated behavior than we originally thought," he said.
Creating a Dinosaur
When National Geographic decides to run a feature story on dinosaurs, Sloan rolls up his sleeves and taps into the network of artists he regularly crosses paths with in the paleontology world.
"When we do a dinosaur story we hire dinosaur artists," said Sloan. "There is so much that goes into portraying a dinosaur accurately that you cannot hire someone unless they know what they are doing."
People like Sibbick and Hallett, whose work has appeared in several issues of the yellow-bordered magazine in addition to other popular magazines, scientific journals, and books, are on the top of Sloan's list. They take their work seriously and, like Sloan, are plugged in to the world of paleontology.
"Once I get a clear indication of what animal or environment we will be portraying, I immerse myself in all the information that is available," said Hallett. He reads scientific papers, visits with paleontologists, and sometimes travels to where the dinosaur was found. He wants a direct impression of what the dinosaur's life was really like.
Sibbick too gathers as much information on the dinosaur as possible. He reads the science papers, talks with paleontologists, and looks for modern animals that could serve as a model for how the dinosaur moved and blended into its environment.
In addition, Sibbick pays close attention to his client. "There is a lot more controversy now, so you have to take on board who is saying what, who believes what, especially when working on commission," he said. "You have to know where the client is coming from."
Then, for the next several months, at times for as long as year, the artists, scientists, and Sloan go back and forth, revising and evolving the piece from a rough conceptual pencil sketch to a vibrant, action-packed, and scientifically-accurate scene ready for publication.
"You got to be kind of relaxed about stopping and rethinking," said Sibbick, who has seen deadlines pushed back several months in order to get a piece as accurate as possible. "You got to make sure most people are as happy as they can be."
Sloan says the artists he regularly collaborates with are a unique group who are dedicated to the science that is the basis of their work. "They see their art as being the best way the scientists can communicate the importance of their work to the public," he said.
