Fossil Fish Host Rock - Utah Customers Only


Product Description

Ideal for classrooms, family science nights, and science fairs.

All of those cool fish we have come from a layer of sedimentary rock that is snuggled into SW Wyoming.  Tip the rock on end and, using a chisel and hammer, split the rock into sections, not unlike splitting a loaf of bread. You will find fish, insects, leaves, and other critters preserved in the rock layers. This is the same process that paleontologists in the field use to find fossils. In essence, we bring the fossil dig to you. Saves on time and gas money, but is just as dusty as a real dig site. The rock is called siltstone and it has two very noticeable characteristics. First, it is very soft. Second, it is laminated, or splits into layers very easily. This is because the siltstone was formed, layer upon layer, as lake sediments settled to the bottom of the lake bed. Once compressed and hardened, these layers provide natural fracture zones when splitting the rock. Fossil Profile: Fish/Knightia.

Chisels can be returned for a full refund when you are finished with them.
