This page shows you insect fossils (not in amber) that are available for the collector of rare specimens. Since insects are so fragile, fossil remains of insects are very hard to get. The reason for the scarcity of insect fossil is the poor preservation potential of the insect’s exoskeleton. Like other arthropods, insects have an external skeleton called an exoskeleton. Unlike the thick and calcified trilobite exoskeleton, the insect exoskeleton is made of a thin, plastic-like material called chitin, along with a tough protein. This thin, waterproof covering simply does not preserve well in most oxygenated environments, making insect fossils sparse despite the tremendous number that could have been preserved. We find areas of the world that have these rare fossils and bring them to you.
