Gastropod Shell Fossils - Morocco 400 Million Years Old Dimensions: 0.5-1.5 inches Age: 400 million years old (Devonian Period) These genuine Fossils from Morocco would make a treasured addition to your personal collection, as well as a unique gift. Gastropods are snail-like & slug-like invertebrate (lacking a backbone) animals, & are types of mollusks. Snails have hard mineral shells; slugs lack shells. Because fossils mostly represent the hard parts of organisms, snails are the most common types of gastropod fossils. Slugs are not preserved as fossils. Snails have a single, coiled shell. Modern snails include some of the most common seashells on beaches today, including conch, cowrie, limpet, olive, murex, turban, turret, & whelk shells. Some snails are carnivorous predators, some are herbivores, some are detritus feeders, & others are scavengers. Different species live in fresh, brackish, & marine water. Modern gastropods mostly live on a substrate (sediment or other objects) or burrow in the substrate. You will receive a lot similar to the ones in the photos.
