Invertebrate fossils
For many fossil collectors, they rank as the most intriguing of ancient life forms, usurping even the hallowed dinosaur. From their rise at the beginning of the Cambrian, to their demise at the end of the Permian Period some 300 million years later, trilobites, in all of their multi-segmented glory, represent one of early life's most intriguing .../ Invertebrate Fossils / Echinoids. Echinoids (sea urchins) are echinoderms. They have a globe-, heart- or disk-shaped skeleton of interlocking plates of calcium carbonate that is covered by a thin layer of skin.

In Kansas, fossil sponges can be found in the Pennsylvanian ...They deal with fossils that are millions of years old, like 6-million-year-old bone-crushing dogs (and their poop). And then there is the Dinosaur Institute, which has many fossils older than 100 million years. And even that, while definitely old, is nothing compared to some of the specimens in Invertebrate Paleontology.
The fossils are named after the Greek scientist and philosopher Archimedes, who designed a corkscrew-shaped irrigation pump.

Snails (gastropods) are molluscs that usually have a coiled shell made of calcium carbonate with an opening or aperture at one end. The head and foot (a muscular organ used for creeping over the surface) emerge from the aperture and can be pulled back into the shell for protection.
