Regrettably, the best museums and professional paleontologists can hope for is that like the market for Beanie Babies, the cost of the best fossils collapses to a more respectable level. Trace fossils represent a data source that reflects animal behaviors, and they do not require the preservation of hard body parts. It is such dyes as these that led to certain shades of purple and blue being associated with royalty and wealth. Snail climbing stone slabs at Servia, Greece.

Belemnite guards and squid hooks have been found in huge numbers in the guts of ichthyosaurs and sharks. On the other hand, many mosasaur species evolved teeth that are excellent for crushing shells. Some previous studies based on chemical analyses of rocks had suggested that the worlds seas were acidic at that time, but other geochemical evidence suggested the opposite, said Foster. A shell-less animal is much more maneuverable and compressible, so even quite large land slugs can take advantage of habitats or retreats with very little space, retreats that would be inaccessible to a similar-sized snail. But the prevalence of both ammonites and mosasaurs, as well as overlapping habitats and depth limitations seem to point in a direction that favors this predator-prey relationship. While a complete skeleton may be worth an enormous amount of money, a fragment .
