Crinoid Stem Fossils, 8 Ounces to 5 pounds Bulk - Free US Shipping

The crinoid stems in this listing are fossilized portions of animals that lived approximately 300 million years ago in a sea that covered most of Texas. These are sometimes called "Texas Pop Rocks" or "Indian Pop Rocks" because they can explode, much like popcorn, when thrown into an open fire. They have also been referred to as "Indian Beads" since they are known to have been worn by the indigenous people of North America.

This material is being made available in four different quantities: 8 ounces, 1 pound, 3 pounds and 5 pounds. The exact pieces that will be shipped are shown in the listing photographs. All have been washed however a small amount of the rock matrix that once held the pieces is present on a portion of the specimens.

The majority of these crinoid stems are not the soft, limestone casts that are more commonly found. They were preserved when silicate minerals replaced the crinoid tissues giving many of them a somewhat crystalline appearance. They are also more colorful than many other crinoid fossils, especially when viewed wet. These fossils would be appreciated by the seasoned collector, educator or anyone interested in a piece of the Earths prehistoric past.
