[多项选择]What are the ways of preserving fossils mentioned in the discussion
[Clink on 3 answers.]
A. Fossils can be preserved as moulds.
B. Fossils can be preserved through cauterization.
C. Fossils can be preserved through dehydration.
D. Fossils can be preserved as frozen dead bodies.
E. Fossils can be preserved in some chemical liquid.
[单项选择]Fossils of the coral Aerocora palmata that date from the last period when glaciers grew and consequently spread from the polar regions are found at ocean depths far greater than those at which A. palmata can now survive. Therefore, although the fossilized A. palmata appears indistinguishable from A. palmata now living, it must have differed in important respects to have been able to live in deep water.
The argument depends on the assumption that
A. A．no fossils of the coral palmata have been found that date from periods when glaciers were not spreading from the polar regions.
B. B．geological disturbances since the last period during which glaciers spread have caused no major downward shift in the location of palmata fossils.
C. C．palmata now live in shallow waters in most of the same geographical regions as those in which deep-lying palmata fossils have been found.
D. E．(E) palmata can live at greater depths where the ocean temperature is colder than they can where the ocean temperature is warmer.
[单项选择]In almost all cases the soft parts of fossils are gone for ever but they were fitted around or within the hard parts. Many of them also were attached to the hard parts and usually such attachments are visible as depressed or elevated areas, ridges or grooves, smooth or rough patches on the hard parts. The muscles most important for the activities of the animal and most evident in the appearance of the living animal are those attached to the hard parts and possible to reconstruct from their attachments. Much can be learned about a vanished brain from the inside of the skull in which it was lodged.
Restoration of the external appearance of an extinct animal has little or no scientific value. It does not even help in inferring what the activities of the living animal were, how fast it could run, what its food was, or such other conclusions as are important for the history of life. However, what most people want to know about extinct animals is what they looked like when they were ali
A. equally important.
B. definable.
C. equally doubtful.
D. deliberate.
