The eggs of certain snail species are eaten in a fashion similar to the way caviar is eaten. Both species were extremely diverse and prevalent, especially in the Cretaceous. Part of the problem is that many dealers simply dont have the knowledge of the fossil preparation process to be able to recognize this restoration themselves. Their texture when cooked is slightly chewy and tender. To approach a question 400 million years in the making, researchers turned to mudskippers, blinking fish that live partially out of water. The average life span of these amazing creatures is 2.5-3.5 years. Snails entombed in amber are rare, let alone extraordinary snail specimens that have soft parts, says coauthor Jeffrey Stilwell, a paleontologist at Monash University in Melbourne, Australia. Many snails are herbivorous, eating plants or rasping algae from surfaces with their radulae, though a few land species and many marine species are omnivores or predatory carnivores. Fossils can either be body or trace fossils. The park pumped out $2 billion worth of noodles last year. The practice of rearing snails for food is known as heliciculture.
