Paleozoic-Fossil Identification Review
Chart and pictures
The next 9 slides contain general information about some of the
phylum and organisms
Protista
The Protista, = a kingdom of simple eukaryotic organisms, usually composed of a single cell or a colony of similar cells. Protists live in water, in moist
terrestrial habitats, and as parasites in the bodies of multicellular eukaroytes.
Protozoa- Single celled (Amoeba) Porifera- Body with pores( sponge)
Cnidaria- Tentacles/ Stinging cells (corals) Arthropods-Jointed bodies or legs (Insects)
Mollusks - animals with shells (Snails, clams) Echinoderms- spiny skinned (starfish)
Phylum Porifera - The Sponges
Name means "pore-bearing". Covered by tiny pores.
CORALS Phylum = Cnidaria
BIVALVES Gastropods
Phylum = Mollusca
Snails and slugs Chief characteristics: Asymmetrical, spiral-coiled calcareous shell.
means " two" (bi) + " shells" (valves
Clams, oysters, scallops, mussels, rudists Chief characteristics:
Skeleton consists of two sections connected by a hinge.
Phylum- Mollusk-Extinct Cephalopod- Belemnites • Belemnites have shell that resembles a cigar
rostrum. • The belemnites were highly successful during the
Jurassic and Cretaceous.
similar to the modern squid and closely related to the modern cuttlefish.
Ammonites
• Ammonites were among the dominant swimming invertebrates in Mesozoic seas.
• were so abundant and varied that the Mesozoic could be called the "Age of Ammonites".
Phylum- Mollusk-Bivalves-Rudists
found in limestone rocks
shallow marine environments
Difference between Brachiopods and Mollusk Bivalves
Bivalves
Sides the same
Cut down the middle= not the same
Phylum Arthropoda
• Insects, spiders, shrimp, crabs, lobsters, barnacles,, trilobites
Phylum Echinodermata
• Starfish, sea urchins, sand dollars, crinoids, blastoids, and others
• Name: Echinodermata means "spiny" (echinos) + "skin" (derma).
Echinoderms Crinoids
Paleozoic Fossil Identification

Graptolites
Kingdom- Animalia Phylum- Hemichordata Class –Graptolites 1. Floated ( like plankton) 2. Colony - formed large floating masses 3 Not a predator 4. Suspension feeders- tentacles 5. Shallow / deep 6. Abundant- Ordovician
42-Chlorophyta
Algae
Kingdom – Plantae Phylum- Chlorophyta Class – Green Algae 1.Floats or becomes Stationary 2. Colony 3. Not a predator 4. Plants produce own food –filter nutrients from the water / bacteria Shallow water- need sunlight 6. Appeared in Archean

Pick up some gear and go find some Trilobites!
Trilobites of the Wheeler Shale, Utah
Western Utah is one of the best-known Cambrian fossil localities in the world
Location of Utah today
Locality of Utah during the
Early Cambrian
Some Notable Trilobite Localities
Trilobites
House Range in Utah, or Coal County in Oklahoma produce some beautiful specimens
