Private collectors have been selling and buying fossils, the petrified remains of ancient organisms, ever since the eighteenth century. In recent years, however, the sale of fossils, particularly of dinosaurs and other large vertebrates, has grown into a big business. Rare and important fossils are now being sold to private ownership for millions of dollars. This is an unfortunate development for both scientists and the general public.
The public suffers because fossils that would otherwise be donated to museums where everyone can see them are sold to private collectors who do not allow the public to view their collections. Making it harder for the public to see fossils can lead to a decline in public interest in fossils, which would be a pity.
More importantly, scientists are likely to lose access to some of the most important fossils and thereby miss out on potentially crucial discoveries about extinct life forms. Wealthy fossil buyers with a desire to own the rarest and most important fossils can spend virtually limitless amounts of money to acquire them. Scientists and the museums and universities they work for often cannot compete successfully for fossils against millionaire fossil buyers.
Moreover, commercial fossil collectors often destroy valuable scientific evidence associated with the fossils they unearth. Most commercial fossil collectors are untrained or uninterestedin carrying out the careful field work and documentation that reveal the most about animal life in the past. For example, scientists have learned about the biology of nest-building dinosaurs called oviraptors by carefully observing the exact position of oviraptor fossils in the ground and the presence of other fossils in the immediate surroundings. Commercial fossil collectors typically pay no attention to how fossils lie in the ground or to the smaller fossils that may surround bigger ones.
Both the reading and listening materials discuss the sale of fossils. The reading, to be more specific, argues that this market is a great loss for both scientists and general public. On the contrary, the lecture holds a different idea and states that the benefits brought about by selling fossils have out-weighted its disadvantages.
The reading begins by stating that fossils are supposed to be exhibited in museums for the public instead of in some private collections. This is challenged by the professor, who feels strong that the public is more likely have greater exposure to these valuable fossils. He further explains this by claiming that the sale of fossils has made it easier for public places like schools and libraries to purchase them; hence, more people will get to see the fossils.
The reading them points out that scientists are bound to miss out on various important information about extinct life forms. The professor, in contrast, asserts that the sale of fossils does not affect the work of scientists. He supports his claim by discussing that all fossils have to be examined and identified by scientists; thus, they still have access to the fossils and the informations they might provide.
The reading finishes by arguing that commercial collectors tend leave out a lot of valuable scientific evidence due to their lack of professional knowledge. The lecturer refutes this idea, claiming that it is better to discover more fossils than leaving them remain undiscovered. Indeed, there are not enough governmental operations needed to carry out these types of field works.
