Paleontologists must sometimes compare the fossils of extinct organisms with living organisms to draw conclusions about the nature, behavior, or habits of prehistoric life forms.
Paleontologists have found fossils of the empty shells of trilobites, for example, that reveal that the animals shed their shell-like skeletons as they grew into adult forms, much as shrimps and crabs do today.
Paleontologists have identified predators and their victims using evidence such as the teeth marks of mosasaurs (large, carnivorous marine lizards) on ammonites.

 Paleontology - Wikipedia, the free encyclopedia
Paleontology (the American spelling; the British spelling is palaeontology) is the study of the developing history of life on earth, of ancient plants and animals based on the fossil record, evidence of their existence preserved in rocks.
Paleontologists are among the more colorful and eccentric figures in the history of science.
Important figures include the Englishman William Smith who first noted that similar fossil sequences were found regionally and Georges Cuvier who initiated the study of ancient animals based on living animals.

 A Major T. Rex Breakthrough (washingtonpost.com)
Paleontologists have recovered what appear to be soft tissues from the thighbone of a 70 million-year-old Tyrannosaurus rex, potentially enabling dinosaur research to make a leap into studying the animals' physiology and perhaps even their cell biology, the research team said yesterday.
But "there's no 'Jurassic Park' scenario," said paleontologist Hans-Dieter Sues, associate director of research and collections at the National Museum of Natural History, adding that the bone is so old that DNA fragments are probably the best that could be hoped for.
The lab work was supervised by Schweitzer, a paleontologist with experience in forensic analysis of modern biological samples, an advantage in a profession in which backgrounds in geology or other earth sciences are more common.

 Frequently Asked Questions
Although most of the fossils that paleontologists study are several thousands to several billions of years old, there is no absolute minimum age for a biological structure to be a fossil.
Paleontologists study these fossils and attempt to use them to reconstruct the history of the Earth and the life on it.
For instance, a paleontologist might identify fossil animal bones or plant pollen associated with an archaeological site, to find out what the people who lived there ate; or a paleontologist might be called on to analyze the climate at the time a particular archaeological site was inhabited.

 Paleontologists duped by fake
The fossil that paleontologists have dubbed the missing link between the evolution of dinosaurs into birds, is now being called a potential fake.
The paleontologists thought archaeoraptor was the missing link between dinosaurs and birds because it had several features of a bird, including not only feathers, but a large breastplate and keel.
The paleontologists noticed that the bones connecting the tail and body were missing and that the fossil showed signs of reworking.

 Geologist: Dinosaur Paleontologists Often Neglect Rocks and Sediments   (Site not responding. Last check: 2007-11-07)
Dinosaur fossils are so popular and sparse that paleontologists who specialize in dinosaurs tend to focus more on finding trophy fossils than expanding their knowledge about dinosaurs, Schmitt said.
Paleontologists who care about science — Schmitt includes Jack Horner and the other MSU paleontologists in that group — can learn valuable lessons from the rocks and layers where the fossils are embedded, Schmitt said.
For that reason, MSU is trying to train its undergraduates, the next generation of paleontologists, to include rocks and sediments in their dinosaur research.

 Paleontologists discover new dinosaur species   (Site not responding. Last check: 2007-11-07)
OKLAHOMA CITY: Paleontologists have found bones in Oklahoma from a previously unknown species of dinosaur and one of the biggest ever discovered: a 60-ton giraffe-like creature that could have peered into a sixth-story window if there had been any buildings around 110 million years ago.
Matt Wedel, a leader of the University of Oklahoma research team, named the 60-foot-tall species of sauropod Sauroposeidon proteles, or "thunder lizard." Its name is derived from Poseidon, the Greek god associated with the sea and with earthquakes.
The creature was so big that "even if it tried to do so gingerly, it would create a little seismic activity" when it walked, said University of Oklahoma paleontologist Richard Cifelli.
