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 uninterested in 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.
The lecture casts doubts on the passage that commercial fossil business is an unfortunate development for both scientists and the general public. Instead, the lecture asserts that commercial fossil business brings more advantages than negative effects.
First of all, the passage claims that selling fossils to private collectors would decrease the opportunity for public to see fossils, which lead to a decline in public interest in fossils. However, the lecture counters the claim by pointing out that commercial fossils business lower the criteria for people who are able to join it. Thus, even low level public institutions are able to be buyer for fossils.
Secondly, the passage states that selling fossils to private collectors would make scientists lose access to some of the most important fossils. Nevertheless, the lectures opposes the statement. The lectures argues that although fossils are sold to private collectors, before them get to the buyers they would have to pass through scientists first. Therefore, scientists do not miss out the chance to collect the data.
Finally, the passage mentions that commercial fossil collectors are untrained or uninterested in carrying out the careful field work and documentation that reveal the most about animal life in the past. Notwithstanding, the lecture denies the passage by arguing that there are not many universities run fossil excavation. And without commercial fossil businesses, there would be more fossils remain undiscovered.
