Two, Jurassic Belemnite (Passaloteuthis) Fossils

Here are two fossil belemnites (Passaloteuthis sp.) from the Jurassic age, Posidonia Shale of Holzmaden, Germany. These belemnites were prepped free of the shale they were found in, and are mounted to this section of shale that comes from the same locale. One belemnite measures 3.2" long while the other is 2.55" long.

Earth Science Rocks and Minerals Review Quiz

The diagram shows a process that is used to separate gypsum from shale on the basis of density. Crushed rock is dropped into a mixture of liquid and small particles, called a slurry. The data tables show the mass and volume of 3 samples of gypsum and 3 samples of shale after they were separated by this process.

ROCKS and how to identify them.ppt

Shale - fragmental SHALE is a very common rock made of silt and clay sized particles. It is generally very thin-bedded and splits along the bedding planes. In fact, the name is probably from the Old English scealu, "shell or husk". Normally gray to black, shale may be brown to dark red, depending on the amount of included iron oxide.
