Welcome to Invertebrate Paleontology
Invertebrate Paleontology is the study of fossil animals that lack notochords (non-vertebrates). This includes large, diverse taxonomic groups such as mollusks (e.g., bivalves and gastropods), brachiopods (e.g., lamp shells), corals, arthropods (e.g., crabs, shrimps, and barnacles), echinoderms (e.g., sand dollars, sea urchins, and sea stars), sponges, annelids (worms), foraminifera (single-celled protists), and bryozoans (moss animals).
These are all animals that, throughout most of Earth’s geological history, lived in a multitude of habitats including marine, freshwater, and terrestrial. Fossils are any trace of a previously living organism, although invertebrates do not have “true” bones they do leave behind evidence of their past in the form of shells, molds and casts, track ways, fecal pellets, tubes, and exoskeletons. Fossil Invertebrates are useful in many types of scientific studies, including pure systematics, applications in stratigraphy, and the study and reconstruction of prehistoric environments.
The Florida Museum’s Invertebrate Paleontology Collection is largely composed of fossil invertebrates from the Cenozoic Era (last 65 million years) collected from Florida, the southeastern U.S., and the circum-Caribbean. The collection is composed of five main parts: Systematic Collection, Stratigraphic Collection, Teaching Collection, Micropaleontology Collection, and Type and Figured Collection.
- The largest is the Systematic Collection, where specimens are arranged in phylogenetic order. This collection, which acts much like a library, is used in comparative studies and aid in identification.
- The Stratigraphic Collection is used in determining the age and type of sediments fossils are discovered in. Material collected in place is organized by location and stratigraphic sequence in this collection.
- The Teaching Collection contains material from the Mesozoic and Paleozoic Eras. It serves as a resource to educators demonstrating life’s diversity throughout the ages.
- The Micropaleontology Collection contains foraminifera and ostracods (bivalved arthropods) both valuable in stratigraphy and paleoecology.
- The type and figured collection contains specimens cited in scientific publications.
