The following questions were answered by dinosaur expert Don Lessem, paleontologist Tim Rowe, and paleontologist Bill Hammer.
A: The accuracy of Michael Crichton's rendering of dinosaurs in Jurassic Park varies (I have not read The Lost World). He certainly goes overboard on velociraptor in terms of intelligence, and in the film its size was about three times the size of actual specimens. Velociraptor is a close relative of modern-day birds, but it has a somewhat smaller brain and thus its behavior patterns were no more complex than what one would find in a bird today. You might keep in mind that Crichton's books are science fiction, and that he is not one to let the truth get in the way of a good story. (Tim Rowe) Yes, I thought by and large the dinosaurs from Jurassic Park were the best ever done. The triceratops and T. rex in particular looked very much like what scientists think they might have, except that T. rex's teeth might well have closed in its mouth (not hung out) and the arms were also a little long. But there were still many inaccuracies, and interesting ones. The dinosaurs were bigger, faster and smarter overall than we think they were sort of like dinosaurs on steroids. The gamekeeper says velociraptor was "as smart as a chimp, as fast as a cheetah, and they can remember." I don't know about remembering but it's more likely they were dumber than ostriches and slower than us. They were only as big as standard poodles! The spitter is dilophosaurus, a dinosaur that was really the first big meat-eater, 20 feet long and as far as we know it didn't spit poison or have a neck frill that fanned out. Most of the dinosaurs in the movie are Cretaceous not Jurassic animals. (Don Lessem)
Q: In the book The Biggest Dinosaurs by Michael Berenstain, it says that
the seismosaurus, found in Mexico, might be larger than the ultrasaurus.
Do you know if this is true?
A: Ultrasaurus was the biggest we know, but we only know it from a few
bones. It appears to be a brachiosaur, which was giraffelike and heavily
built. Seismosaurus was indeed longer, the longest we know, and we know
it from a whole back end. It was a diplodocus relative, a longer-bodied
animal with a whip tail but not so heavily built. It comes from New
Mexico. (Don Lessem)
Q: What do you think of Bakker's Dinosaur Heresies?
A: I'm not all that keen on Bakker's Dinosaur Heresies as a work of
science, though it is very entertaining. Many scientists call it
Dinosaur Hearsay, since he substitutes his own creative opinions for
hypotheses based on hard data. For instance he opines that some
four-legged dinosaurs gave birth to live young and does some sloppy work
with predator-prey ratios (Jim Farlow has done much better) to justify
his hot-blooded dinosaur hyperbole. (Don Lessem)
Q: What are some good dinosaur books for eighth graders?
A: I like books written by scientists themselves, such as the works of
Dr. Farlow, Weishampel, Dodson, Benton, Horner, Bakker, or Norman. Look
out for their names on books for older kids and grown-ups. (Don Lessem)
Q: What is a good book about dinosaurs in general?
A: In Dinosaurs Rediscovered (Simon & Schuster), I deal with the quality
of Bakker's science, and the issues of extinction, warmbloodedness, and
much of current dinosaur research. (Don Lessem)
Q: What is a good book about T. rex?
A: Dr. Jack Horner and I wrote a book for adults all about T. rex,
called The Complete T. rex (Simon & Schuster). (Don Lessem)
Q: What is a good book about caveman bones?
A: I did write a book, The Iceman, about a 5,000-year-old mummy recently
found in ice in Europe. The mummy still had all his stuff, including a
copper ax, fannypack and knife. It was a cool discovery. (Don Lessem)
Q: Will you continue to publish and write books on dinosaurs?
Do you
have any new works coming out?
A: I'm writing a bunch of new books. I have one that just came out on
the rainforest called The Amazing Amazon, with neat foldout paintings of
weird animals. In the spring I have eight books coming out, four on
individual dinosaurs: Seismosaurus, the longest; Utahraptor, the
meanest; ornithomimus, the fastest; and troodon, the smartest (published
by Carolrhoda). And I have four books in a series called Dinosaur
Worlds, which shows a lot of the animals that lived with dinosaurs as
well as the dinosaurs from different times (published by Boyds Mills).
Next fall I have a book on raptor dinosaurs (Little, Brown) and one on
giganotosaurus (Crown) coming out. (Don Lessem)
