  • A collection of coprolite at a fossil fair. Coprolites are the fossilized feces of prehistoric animals. As it is very rare that a sample can be accurately related to a specific genus of animal, coprolites are classified according to their own taxonomy. Particularly well-preserved examples may reveal data on the animal's diet, especially in more recent mammals such as bears and cave lions. Fossil fairs provide a forum for amateur and commercial collector to trade in prehistoric remains. Although frowned upon by many academics, amateur paleontologists have often made finds of previously unknown species. (1991)

  • Fossilized remains of a prehistoric fish (Lepidotes). This example has been particularly well preserved, with the scale patterns and the large, bony head clearly defined. This fish was about 80cm in length, and was found in the Holzmaden area of Germany. Such a piece commands very high prices at fossil fairs, such as the one at Tucson, Arizona. (1991)

  • Designed to run freely on its own, untethered to any external wires, Troody is modeled after Troodon formosus, a carniverous dinosaur that was reputedly the most intelligent creature in the late Cretaceous era. Troody's designer, MIT Leg Lab staff researcher Peter Dilworth, wants to put such prehistoric creatures in museums. The idea has been embraced by Gregory S. Paul, a prominent paleontologist. This portrait was taken at the university boat dock on the Charles River in Cambridge, MA, Troody lapsed into immobility. From the book Robo sapiens: Evolution of a New Species, page 115.

  • Mammoth skeleton. Side view of the largest mounted Mammuthus columbi skeleton in the world. It is housed at the University of Nebraska State Museum, USA. At upper left are giant up-curved tusks. This specimen is 4 meters in height. Mammuthus columbi (Columbian mammoth) was a giant elephant-like mammal, which roamed temperate parts of North America more than 10,000 years ago, when it became extinct. This species was an important later relative of the woolly mammoth of Europe and Siberia. These well-preserved bones of Mammuthus columbi were discovered in Lincoln County, Nebraska, in 1922, a site famous for its fossils. The skeleton was assembled in 1933. 1992.

  • Very fine examples of fossilized ammonites, Sphenodiscus. The brilliant opalescent colors are due to mineral crystallization, which occurred during the fossilization process. This makes the fossils very valuable on the commercial market. The ammonites (subclass Ammonoidea) were marine mollusks, which had a clearly defined head with tentacles for gathering food. They first appeared in the Lower Devonian period (400 million years before present), becoming extinct at the end of the Cretaceous period (65 million years BP). (1991)

  • A German fossil expert carrying the skull of a fossil fish, Xiphactinus. This photo was taken in a motel in Tucson, Arizona, during the annual Fossil Fair. Amateur and commercial collectors gather at the fair to trade in fossil remains. Although many academics are unhappy with such events, amateur collectors frequently discover the remains of previously unknown species or very fine examples of known species. Such fossils are recovered from private land: in the USA private individuals are rarely granted the special license needed to hunt for fossils on public land. MODEL RELEASED (1991)

  • Fossil mammoth site. View of the largest collection of Columbian mammoth fossils (Mammuthus columbi) in the Western Hemisphere. Visitors receive a commentary while looking at excavated bones at the Hot Springs Mammoth Site in South Dakota, USA. Here, the fossilized skeletons of at least 43 mammoths lie, buried for 26,000 years. It is thought these animals became trapped in a large sinkhole when they came to drink water. Mammuthus columbi was a giant elephant-like mammal, some 4 meters in height, which roamed temperate parts of North America. It was an important later relative of the woolly mammoth of Europe and Siberia. This fossil site was discovered in 1974. 1992.

  • Fossil fraud: Christian Ratsch, a fossil expert, holding a stone containing three fossilized trilobites. The three fossils are, themselves, genuine, but had been bonded together to raise their collective price. An amateur collector may not have noticed this fraud. The trilobites are an extinct class of marine arthropods, which lived between the Cambrian Era (570 million years before present) and the Permian Era (230 million years BP). Although generally small in size, averaging 8cm in length, some specimens of 70cm length have been seen. MODEL RELEASED (1991)

  • Fossilized remains of a snake. The snakes evolved from monitor-like lizards some time toward the end of the Cretaceous Period (65 million years before present). The first types to evolve were the boas and pythons; the venomous snakes are not known before the Eocene Period (c.30 million years BP). (1991)

  • April and Barry James, commercial paleontologists, holding the tusk of a Siberian Mammoth. Just behind them is a prepared and mounted skeleton of a Cave Bear (Ursus spelaeus), which was widespread throughout Europe in the Pleistocene Period about 2 million years ago. A skeleton in this condition can be purchased for about $35,000. Academics often frown upon such collectors, but amateurs have discovered many new species across the world. Incisor tooth comes from Siberian Mammoth. MODEL RELEASED (1991)

  • A very fine example of a fossilized ammonite (Hoploscathite). Although the shell itself has not been preserved, the internal nacre has survived, giving the opalescent 'mother of pearl' coating. Ammonites were a subclass of marine mollusks, which had a well-defined head with tentacles for feeding. They first appeared in the Lower Devonian period (400 million years Before Present), becoming extinct by the Upper Cretaceous period (65 million years BP). (1991)

  • Bone of a mammoth. Paleontologist George Corner carries the fossil elbow (ulna) bone of a mammoth, Mammuthus columbi. Racks of mammoth jawbones and teeth can be seen in this room at the University of Nebraska State Museum, USA. Mammuthus columbi (Columbian mammoth) was an elephant-like mammal, which roamed temperate parts of North America more than 10,000 years ago, when it became extinct. This species stood 4 meters high, and was an important later relative of the woolly mammoth of Europe and Siberia. The bone was discovered in northwest Nebraska between mammoth fossil jaws. This State Museum houses the largest mounted Mammuthus columbi skeleton in the world. MODEL RELEASED (1992)

  • Dan Ulmer and wife, two fossil merchants share their motel room with a variety of large fossils. On the table next to the bed is a leg bone from a dinosaur and the skull of a prehistoric rhinoceros-like animal (Brontotherium sp.). Brontotherium was a genus of mammals that lived in the Lower Oligocene period about 35 million years ago in what is now North America. This photo was taken during the Fossil Fair at Tucson, Arizona, where amateur and commercial fossil collectors gather to trade in the remains of prehistoric animals. Although frowned upon by many academics, amateur collectors frequently find remains of new fossil species or very fine examples of known species. MODEL RELEASED (1991)

  • Studying the creation of life. A scientist adjusts equipment during a re-run of the Miller-Urey experiment into the origin of life. A flask containing a mixture of water, hydrogen, methane and ammonia has an electric field applied across it. A ultra-violet laser is used to illuminate the mixture and to stimulate an electrical discharge in the mixture. This experiment, devised first by Stanley Miller and Harold Urey in 1952, produces a mixture of 'pre-biotic' chemicals such as amino acids. It is suggested that the roots of life on Earth rest in prehistoric, global versions of this process. Photographed at the NASA Ames Research Center, California. MODEL RELEASED 1992.
