Arthropod - Ostracods | Ostracods are group of microscopic, shrimp-like arthropods that lived within a pair of hinged shells. They originated in the Early Ordovician and still inhabit oceans and even fresh water today. Although the shells are very small, seldom exceeding one millimeter in length, many of them are intricately ornamented. In the Finis Shale, ostracods are not uncommon in the very small size fraction (40-60 mesh) of washed/sieved matrix. We have identified about 15 species of ostracods, but numerous others are reported in the literature. Confident identifications are hampered by a lack of modern work with detailed descriptions and illustrations. The most common forms vary depending on the specific stratigraphic layer within the Finis, but Cavellina and Hollinella are usually present in most samples and often abundantly. Healdia and Amphisites are common as well. Scroll through images or click to enlarge. Fossils are in alphabetical order by Genus. Collections are from Mike DeBrock (MD), Josh Hanley (JH), Dr. Peter Holterhoff (PH), Mark McKinzie (MM), John McLeod (JM), ), Dr. Ben Neuman (BN), Bob Williams (BW), Sveta Earnest (SE), and Rodney Wise (RW). All scales are shown in millimeters unless otherwise noted. |
