Crinoid Holdfast and Other Fossils Age: Silurian Formation: Waldron Formation Location: Waldron, Indiana Size: Plate is 8.2 inches across Price:$68.00
Here is a very interesting association of fossils. It is a large crinoid holdfast and other fossils from the Silurian of Indiana. The quarry where this specimen was found is now filled with water. This holdfast is very 3-dimensional and exhibits great detail. The stem attachment point is easily seen, and the branching pattern of the ''rootlets'' is clearly defined. There are also gastropods, brachiopods, a crinoid cup, and many other fossils preserved on the plate. The fossils have excellent color and contrast and are well showcased on the large, semi-rectangular plate of dense shale. This is a fabulous example of a Silurian sea floor bottom from the Waldron Shale.
