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.
The reading holds a negative attitude towards the open commercial market about fossils and states three reasons while the lecture disapprove these views and rebuts them.
First, the reading mentions that private collectors can buy fossils and eliminate the chances that the public can see those fossils which supposed to be exhibited in the museums. Instead, the lecture states that with the rising of need, there will have more exposures and more fossils are reachable simultaneously.
Moreover, the reading claims that public bureaus and scientists cannot compete with rich fossil buyers to obtain fossils. Nonetheless, the lecture reminds us before the fossils are being purchased, they should go through a series of examinations and detail tests by professional scientists so the valuable data cannot be ignored or lost.
Finally, albeit the reading declares that many fossil buyers do not treat fossils appropriately and leads to valuable information missed out, the lecture refutes it since there are too few fossils had been discovered. With enough quantities of exposed fossils, the public and scientists can benefit from them.
