Which fossils do invertebrate paleontologists study
Fossil invertebrate animals (animals without backbones) are a wondrously diverse group with a fossil record spanning over 600 million years. Their abundance, diversity, and wide range of adaptations make them an ideal resource for scientists to use in understanding how our planet has changed over time. Paleontologists at the Field Museum and from around the world study fossils in our ...• Echinacea (for Stirodonta and Camarodonta) • Gnathostomata (irregular echinoids with a lantern; for Clypeasteroida, Holectypoida [excluding the Pygasteridae], Conoclypidae and Oligopygidae [attributed to the Cassiduloida by Mortensen]) •

The “Cambrian explosion” is a poorly-defined term that refers to a period of time some 600–500 years ago (“Geon 5” [Hofmann, 1990]) during which the biosphere, as reflected in the eukaryotic fossil record, underwent a great expansion.Most popularly, the appearance in the fossil record of the first undoubted …Defining Ages, Epochs, Periods, and Eras. Index fossils are used in the formal architecture of geologic time for defining the ages, epochs, periods, and eras of the geologic time scale. Some of the boundaries of these subdivisions are defined by mass extinction events, like the Permian-Triassic extinction. The evidence for these events is found ... ….
