Offered above are five Crinoid of the Mississippian Period found in the Chesterian Zone of the Bangor Limestone Formation (ca 325,000,000 yrs old) in northern Alabama. Included are Zeacrinus, Dasciocrinus, Aphelecrinus and two Phacelocrinus. This item takes up the about 80% of the USPS Small Flat Rate box so you have room for more fossils without added postage if you wish to do combined shipping. If you do please do NOT pay for this. Just keep shopping to add to the box. I\'ll let you know about available space. I\'ll send you a combined shipping invoice. Do not pay without the invoice. I have found a wonderful resource for collectors who wish to learn identify fossils of the Bangor Limestone Formation such as I offer. \"Fossil Identification Guide for the Tennessee Valley\" is a two volume ebook available only online at Amazon and Barnes and Noble. An updated color PRINT edition titled \"Fossils of the Tennessee Valley\" is also available at the same locations. The photos are fantastic.
